Understanding the basic mechanics behind the operation of a pen is essential before troubleshooting its issues.

Before we delve into the frustrating world of pen malfunctions, let’s establish a foundational understanding. Knowing how these everyday writing instruments actually function is the first step in diagnosing why they sometimes fail us at the most inopportune moments. Whether you’re a seasoned writer or just jotting down a quick note, a little knowledge about the inner workings of your pen can go a long way.

Fundamental Principles of Pen Operation

Pens, in their various forms, all share a common goal: to deposit ink onto a writing surface. The magic, however, lies in the ingenious mechanisms that make this seemingly simple task possible.Ballpoint pens, the workhorses of the writing world, rely on a small rotating ball bearing at the tip. As the ball rolls across the paper, it picks up ink from the reservoir and transfers it.

Gravity plays a crucial role here, as it helps the ink flow down from the reservoir to the ball. The viscosity of the ink is carefully calibrated to prevent it from flowing out too quickly (causing blobs) or drying out too slowly (leading to smudging).Gel pens take a slightly different approach. They use a water-based ink that is thicker than ballpoint ink.

This thicker ink flows more smoothly, producing bolder lines and a more vibrant color. The gel ink is held in a reservoir and, similar to ballpoints, is delivered to the paper via a ball bearing. The difference lies in the ink’s composition; gel inks dry quickly, reducing the chance of smearing.Fountain pens, on the other hand, are the epitome of writing elegance.

They use a reservoir filled with liquid ink, and the ink is fed to the nib (the writing tip) through a complex capillary system. This system relies on the principles of capillary action and gravity. Capillary action allows the ink to travel from the reservoir to the nib, even against gravity. The nib is typically made of metal and has a slit that regulates the flow of ink.

Pressure, exerted by the writer’s hand, also influences the ink flow, making fountain pens capable of producing varying line widths.

This intricate balance between gravity, capillary action, and pressure is what allows fountain pens to deliver a smooth and consistent writing experience.

Rollerball pens, a hybrid of ballpoint and fountain pens, combine the convenience of ballpoint pens with the smooth writing experience of fountain pens. They use water-based or gel-based ink and a ball bearing to deliver the ink to the paper. The ink flow is generally smoother than a ballpoint pen, but it can be more prone to drying out if the pen is left uncapped for extended periods.

The ink reservoir is often refillable, allowing for extended use.

Detailed Comparison of Pen Types

Understanding the differences between various pen types helps in choosing the right pen for a particular task and anticipating potential problems. Here’s a comparison:

Pen Type	Ink Type	Tip Material	Writing Experience	Common Failure Points
Ballpoint	Oil-based	Tungsten carbide ball	Consistent, reliable, can be scratchy	Ink drying out, ball clogging, ink flow issues due to pressure changes
Gel	Water-based gel	Tungsten carbide ball	Smooth, vibrant, bold lines	Ink drying out, ball clogging, skipping, smearing if not dried properly
Fountain	Water-based ink	Iridium-tipped nib (typically stainless steel or gold)	Smooth, expressive, variable line width	Ink flow issues, nib damage, leaks, requires more care and maintenance
Rollerball	Water-based or gel-based	Tungsten carbide ball	Smooth, wet, similar to fountain pen	Ink drying out, skipping, leaks, can be prone to smudging

Typical Internal Components of a Ballpoint Pen

The seemingly simple ballpoint pen is a marvel of engineering, comprising several key components working in harmony.

The ball is a tiny sphere, usually made of tungsten carbide, located at the tip of the pen. Its primary function is to transfer ink from the reservoir to the writing surface. The ball rotates freely as it rolls across the paper, picking up ink and depositing it. The size of the ball (e.g., 0.7mm, 1.0mm) influences the line width produced by the pen.
The ink reservoir is a tube that holds the ink. It can be made of various materials, including plastic or metal. The reservoir’s capacity determines how long the pen can write before running out of ink. The ink itself is usually oil-based and designed to dry quickly to prevent smudging.
The tip housing is the structure that encases the ball and the ink reservoir. It protects the ball and allows it to rotate freely. The tip housing also helps to regulate the flow of ink. The tip’s design can vary, with some pens having a more conical shape and others having a more cylindrical shape.

Identifying the type of pen you are using can help determine the potential causes for its failure to write.

Knowing the type of pen in your hand is the first crucial step in diagnosing why it refuses to cooperate. Different pen types have distinct mechanisms and, consequently, different failure points. Recognizing these differences will significantly streamline the troubleshooting process, allowing you to focus your efforts where they’ll be most effective. This proactive approach saves time and reduces frustration.

Differentiating Pen Types: Visual Characteristics and User Experiences

The world of pens is diverse, but understanding the core types—ballpoint, gel, and fountain pens—is key. Each type presents a unique visual signature and a characteristic writing experience.

Ballpoint Pens: These are the workhorses of the writing world. Their tips are typically a small ball bearing that rolls to dispense oil-based ink. Visually, the tip is often metal, and the ink cartridges are usually cylindrical. The writing experience is generally smooth, though some users might find it slightly scratchy. The ink dries quickly, making them suitable for everyday use.

A common experience is ink skipping, especially if the pen is held at an awkward angle or if the ball bearing is damaged.
Gel Pens: Gel pens use water-based ink that is thicker and more vibrant than ballpoint ink. The tips are similar to ballpoints but often feature a finer point. The ink flows smoothly, and the colors are often more saturated. They’re popular for their bold lines and artistic capabilities. The primary complaint is that the ink can smudge, especially on certain paper types, and they may run out of ink faster than ballpoint pens.
Fountain Pens: Fountain pens are the most sophisticated. They feature a nib, a split tip that delivers ink from an internal reservoir. The nib’s shape and material (often gold or iridium) influence the writing experience. They offer a luxurious feel and a unique writing style. Fountain pens require more maintenance, including cleaning and refilling.

They can be susceptible to ink flow problems if not stored correctly or if the ink dries out. They are often valued for their elegant writing style and the variety of ink colors available.

Methods for Identifying Pen Type

Several methods can quickly identify the type of pen you’re dealing with.

Checking the Tip: Examine the tip closely. A ballpoint pen will have a small ball bearing. Gel pens also have a ball bearing, but the tip may be more delicate. Fountain pens have a distinctive nib.
Ink Color and Flow: Ballpoint inks are generally oil-based and have a consistent flow. Gel inks are often more vibrant and can have a thicker flow. Fountain pens offer the widest range of ink colors and flow characteristics, dependent on the nib and ink.
Writing Characteristics: Ballpoint pens provide a relatively consistent line width. Gel pens often have a bolder, more saturated line. Fountain pens offer a variety of line widths depending on the nib. The writing experience varies significantly: ballpoints can feel scratchy, gel pens are generally smooth, and fountain pens offer the smoothest writing experience.

The ink inside your pen is the lifeblood of its functionality, a carefully crafted concoction that allows words and ideas to flow onto the page. Understanding the various types of ink, their unique compositions, and the quirks that can lead to a frustrating non-writing experience is crucial. Let’s dive into the fascinating world of pen inks and uncover the secrets behind their performance.

Ink Types and Their Characteristics

Let’s explore the different ink types that populate the pen world, each with its own personality and potential pitfalls.Ballpoint ink is perhaps the most ubiquitous, found in the everyday pens that populate our desks and pockets. This ink is typically oil-based, composed of pigments suspended in a viscous solvent. The viscosity, or thickness, of ballpoint ink is a key characteristic.

A high viscosity helps the ink adhere to the ballpoint and prevents it from leaking, while also enabling the formation of a clear line on the paper. However, this thickness can also be a source of problems. If the ink becomes too thick due to drying or exposure to extreme temperatures, it may not flow properly to the ball, resulting in skips or a complete failure to write.Gel ink, on the other hand, presents a different experience.

Gel inks are water-based and contain pigment particles suspended in a gel-like substance. This unique composition allows for vibrant colors and a smooth writing experience. The gel also makes the ink less prone to bleeding or feathering on paper. The formulation of gel inks is critical. They can be susceptible to drying out if the pen is left uncapped for too long.

Furthermore, the gel can sometimes solidify or clump, particularly if the pen is exposed to significant temperature fluctuations.Fountain pen ink offers a touch of elegance and a wider range of ink choices. Fountain pen inks are generally water-based, and they are designed to flow freely through the pen’s nib and feed system. They are often less viscous than ballpoint inks, allowing for a more expressive writing style.

The composition varies widely, with some inks using dyes and others using pigments. The choice of ink can affect the performance. Certain inks can clog the delicate feed system if they contain too much sediment or dry out too quickly. Regular cleaning and maintenance are often required to ensure optimal performance. A fountain pen’s performance also relies on the paper used.

Using a paper with a rough surface can cause the nib to drag, while using absorbent paper can lead to feathering.

Factors Affecting Ink Flow

Several factors can conspire to disrupt the smooth flow of ink from your pen. Understanding these factors can help you troubleshoot and revive a reluctant writer.The following list highlights some of the most common culprits:

Ink Viscosity: As mentioned, the thickness of the ink plays a critical role. Too thick, and it won’t flow; too thin, and it might leak or bleed. Environmental conditions, such as extreme temperatures, can affect ink viscosity.
Air Bubbles: Air bubbles trapped within the ink reservoir can block the ink’s flow, preventing it from reaching the tip. These bubbles can form due to changes in pressure or the pen’s position.
Tip Obstruction: Debris, dried ink, or even tiny paper fibers can clog the pen’s tip, hindering ink delivery. This is more common in pens with finer tips.
Environmental Conditions: Temperature and humidity can significantly impact ink performance. High temperatures can cause ink to dry out or become too thick, while low temperatures can sometimes cause it to thicken and become difficult to flow.
Ink Composition: The specific formulation of the ink, including the type of pigments, solvents, and additives, can influence its flow characteristics. Some inks are more prone to drying out or clogging than others.
Pen Design: The design of the pen, including the feed system and the ballpoint mechanism, can also affect ink flow. Poorly designed pens may have issues with ink delivery.

Assessing Ink Flow: A Step-by-Step Process

When your pen refuses to cooperate, a systematic approach is needed to diagnose the problem. Here’s a simple process to assess ink flow:

Check the Ink Level: The most obvious step is to determine if the pen has any ink left. If the ink reservoir is empty, you’ve found your answer.
Observe the Tip: Carefully examine the pen’s tip. Look for any visible obstructions, dried ink, or damage to the ballpoint or nib.
Test on Paper: Try writing with the pen on a piece of paper. Start with light pressure and gradually increase it. Observe the line quality. Does the ink flow consistently, or are there skips or breaks?
Rotate and Tap: Sometimes, a simple adjustment can help. Try rotating the pen while writing, as this can help dislodge air bubbles. Gently tap the pen against a hard surface to encourage ink flow.
Warm the Pen (Optional): In some cases, gently warming the pen (e.g., by holding it in your hands) can help thin the ink and improve flow. Avoid excessive heat.
Clean the Tip (Optional): If you suspect a clog, you can try cleaning the tip. For ballpoint pens, you can sometimes use a soft cloth or a cotton swab to gently remove dried ink. For fountain pens, consult the manufacturer’s instructions for cleaning the nib and feed.

The environment where the pen is stored or used may affect its ability to write.

Ever wonder why your trusty pen sometimes betrays you, refusing to put ink to paper? The environment plays a surprisingly significant role in your pen’s performance, influencing everything from ink flow to the longevity of your writing instrument. Let’s delve into the environmental factors that can wreak havoc on your pens.

Environmental Factors and Pen Performance

Temperature, humidity, and altitude can all conspire against a pen’s smooth operation. Extreme temperatures, whether scorching heat or freezing cold, can alter the ink’s viscosity. Heat can thin the ink, leading to leaks or smudging, while cold can thicken it, making it difficult to flow. High humidity introduces moisture, which can dilute the ink, causing feathering or blotting. Conversely, low humidity can dry out the ink, leading to clogging.

Altitude also matters; changes in air pressure at higher altitudes can affect ink flow, potentially causing leaks or making it harder to start the pen. Think of the experience of trying to write on a plane versus at sea level – the difference is real!

Ideal Storage Conditions for Different Pen Types, Why won’t my pen hit

Proper storage is crucial for maintaining your pens. Here’s a guide to help you preserve your writing companions:

Ballpoint Pens: Store at room temperature (around 20°C or 68°F) and moderate humidity (40-60%). Keep them capped to prevent ink drying. Orientation doesn’t usually matter, but storing them horizontally is generally recommended.

Gel Pens: Similar to ballpoints, gel pens prefer room temperature and moderate humidity. Store them horizontally or with the tip pointing down to keep the ink flowing. Avoid extreme temperatures.

Fountain Pens: Fountain pens are more sensitive. Store them in a cool, dry place, away from direct sunlight. Ideal temperature is around 15-20°C (59-68°F) and humidity around 40-50%. Store them horizontally or nib-up to prevent leaks and ink evaporation.

Rollerball Pens: Like gel pens, rollerball pens benefit from horizontal storage or tip-down storage. Maintain a moderate temperature and humidity level to preserve ink quality.

Troubleshooting a Pen Affected by Environmental Factors

If your pen is acting up due to environmental issues, follow these steps:

Assess the Situation: Consider where you’re writing or storing the pen. Is it excessively hot, cold, humid, or dry?
Relocate the Pen: Move the pen to a more favorable environment. For example, bring a pen that has been stored in a cold car into a room at a comfortable temperature.
Wait: Allow the pen to acclimate to the new environment for a few hours. This allows the ink to adjust.
Try Writing: Attempt to write with the pen. If the issue was temperature or humidity-related, the pen should now function properly.
Clean the Tip (if needed): If the pen still isn’t writing, gently wipe the pen’s tip with a soft, lint-free cloth. This removes any dried ink that might be obstructing the flow.
If Problems Persist: If these steps don’t resolve the issue, other factors, such as ink type or pen mechanics, may be involved. In such cases, further troubleshooting might be necessary.

Physical damage to the pen, such as a clogged tip or a damaged ball, can stop it from writing.

Let’s face it, we’ve all been there. That trusty pen, the one you reach for without a second thought, suddenly decides to stage a silent protest, refusing to leave its mark on the page. While ink type and environmental factors play their roles, sometimes the culprit is simply a case of physical wear and tear. Pens, like any tool, are susceptible to damage, and understanding these common issues is key to getting back to smooth writing.

Common Physical Problems

Pens, in their simplicity, are marvels of engineering. But this very simplicity makes them vulnerable to various forms of physical damage. These issues can range from minor inconveniences to complete writing failure. The most frequent offenders include a blocked tip, a damaged ballpoint, or a cracked ink cartridge.Aclogged tip* is perhaps the most common ailment. Ink, especially in gel or thicker formulations, can dry and harden at the tip, forming a barrier that prevents fresh ink from flowing.

This can manifest as skipping, inconsistent lines, or a complete lack of ink delivery. Think of it like a tiny, ink-based dam.Adamaged ballpoint* is another frequent problem, particularly in ballpoint pens. The tiny ball that rolls to release the ink can become flattened, chipped, or otherwise deformed through regular use or accidental impacts. This damage prevents the ball from rotating smoothly, leading to the same frustrating symptoms as a clogged tip.

The ballpoint is the heart of the pen’s writing mechanism, and its condition is crucial for optimal performance.Finally, acracked ink cartridge* is a more catastrophic issue. The cartridge, whether it’s a refillable reservoir or a disposable unit, can crack due to pressure changes, extreme temperatures, or physical impacts. This can lead to ink leakage, rendering the pen unusable and potentially staining your belongings.

Imagine a small, contained explosion of ink inside your pen.

Visible Signs of Damage

Identifying physical damage often begins with a visual inspection. Recognizing the signs is the first step in diagnosing the problem. Here’s a quick guide to spotting the telltale clues:

Ink Leakage: This is the most obvious sign of a damaged cartridge or a compromised seal. Ink may be visible on the pen’s body, on the tip, or around the refill.
Deformed Tip: The tip of the pen, especially in ballpoint pens, should be perfectly round. Any flattening, chipping, or other deformities indicate ball damage.
Rattling Sound: If you hear a rattling sound when you shake the pen, it could indicate a broken component, such as a detached ballpoint or a cracked cartridge.
Missing or Inconsistent Ink Flow: If the pen is leaving gaps in your writing or producing faint lines, this could point to a clogged tip or a damaged ballpoint.

Inspecting a Pen for Physical Damage

A methodical inspection can often reveal the source of the problem. Here’s a step-by-step approach:

Visual Inspection: Begin by examining the exterior of the pen for any obvious signs of damage, such as cracks, dents, or ink leakage.
Tip Examination: Carefully inspect the pen’s tip. Use a magnifying glass or a jeweler’s loupe for a closer look. Check for any visible blockages, deformities, or dried ink buildup.
Ballpoint Check (for ballpoint pens): Rotate the ballpoint gently with your fingernail or a soft tool. It should rotate smoothly and freely. If it feels rough or sticky, the ballpoint may be damaged.
Cartridge Examination: If the pen is refillable, remove the ink cartridge and inspect it for cracks or leaks. Look closely for any ink residue that might indicate a problem. For disposable pens, a visual inspection of the cartridge through the pen’s body can sometimes reveal damage.
Shake Test: Gently shake the pen and listen for any unusual sounds, such as rattling. This could indicate a broken internal component.

Remember, a little care and attention can go a long way in extending the life of your favorite pen. By understanding the common physical problems and knowing how to inspect for them, you can keep your writing experience smooth and enjoyable.

Incorrect usage or handling of a pen can lead to issues with its functionality.

It’s a common frustration: you reach for your trusty pen, eager to jot down a brilliant idea, only to find it stubbornly refusing to cooperate. While ink type, environment, and physical damage play a role, the way youuse* your pen is often the culprit. Let’s delve into the everyday actions that can sabotage your writing experience and how to avoid them.

Improper Handling and Its Impact

The seemingly simple act of writing is a delicate dance between hand, pen, and paper. Mishandling this trio can swiftly lead to ink starvation. Applying excessive pressure, for instance, forces the ink out too quickly, potentially flooding the tip and creating blobs or, conversely, depleting the reservoir prematurely. Think of it like squeezing a tube of toothpaste with brute force; you’ll get a messy explosion, not a controlled flow.

Writing at an incorrect angle is another common problem. Many pens, particularly ballpoints and rollerballs, are designed to write best at a specific angle relative to the paper. Deviating from this optimal angle can disrupt the ink flow, causing skipping, fading, or complete cessation of writing. Furthermore, leaving a pen uncapped, especially in a dry environment, allows the ink to dry out at the tip, forming a crust that blocks the ink’s passage.

Recommendations for Proper Pen Handling

To ensure your pens consistently deliver smooth, reliable performance, consider these handling practices:

Writing Angle: Experiment to find the ideal angle for your pen. Generally, ballpoints and rollerballs perform best when held at a moderate angle, while fountain pens often require a more upright position.
Pressure: Apply light, consistent pressure. Let the pen glide across the paper; don’t force it. The weight of the pen itself should often be sufficient.
Capping: Always cap your pen when not in use. This prevents the ink from drying out and protects the tip from damage.
Storage: Store pens horizontally to ensure even ink distribution, particularly for pens with liquid ink.
Paper Quality: Use quality paper that can absorb ink correctly.

Demonstration of Correct Writing Angles

To illustrate the importance of writing angles, let’s visualize a few scenarios.
Imagine a standard ballpoint pen.

Scenario 1: Correct Angle

Picture a hand holding the pen at a comfortable, slightly angled position relative to the paper. The tip makes smooth contact, and the ink flows effortlessly, creating a clean, consistent line. The pen is held at roughly a 45-degree angle to the paper.

Scenario 2: Incorrect Angle (Too Flat)

Now, envision the same pen held almost parallel to the paper. The tip barely touches, resulting in skipping, faded lines, or no ink at all. This demonstrates how a flat angle can hinder ink flow.

Next, consider a fountain pen.

Scenario 1: Correct Angle

Picture a fountain pen held at a more upright position, perhaps a 60-70 degree angle. The nib glides smoothly across the paper, depositing ink evenly.

Scenario 2: Incorrect Angle (Too Steep)

Now, imagine the fountain pen held almost vertically. The nib may scratch the paper, or the ink flow might be inconsistent.
These visual examples highlight how the writing angle significantly impacts the performance of different pen types. Practicing the right angle and technique will undoubtedly improve your writing experience.

Specific manufacturing defects in the pen or its components can be the reason it won’t write.: Why Won’t My Pen Hit

Sometimes, even the most sophisticated writing instruments fail us. When a pen stubbornly refuses to cooperate, the culprit may not be user error or environmental conditions, but rather, flaws born during the pen’s very creation. These manufacturing defects, often invisible to the naked eye, can wreak havoc on a pen’s ability to deliver ink to the page, leaving you with nothing but frustration and a blank space where words should be.

Let’s delve into the intricate world of pen manufacturing to uncover the hidden gremlins that can sabotage your writing experience.

How Manufacturing Defects Impede Pen Functionality

A pen’s functionality hinges on a delicate interplay of components. When these components are not perfectly crafted, the pen’s writing ability can be significantly impaired. A poorly formed ballpoint, for example, may have an uneven surface that prevents ink from flowing smoothly, resulting in skips or complete ink failure. Imagine the tiny ball, the heart of a ballpoint pen, as a miniature marble.

If this “marble” is not perfectly round, or if its seating within the pen tip is flawed, it won’t rotate properly, failing to pick up and deposit ink. A blocked ink channel, the passageway through which ink travels from the cartridge to the ballpoint, can be another source of trouble. Minute obstructions, like dried ink particles or microscopic debris left over from the manufacturing process, can completely halt ink flow.

Consider the ink cartridge itself: a defective cartridge, whether it’s a cracked body or an improperly sealed reservoir, can lead to leaks, air bubbles, or insufficient ink supply, all of which will prevent the pen from writing. The ink might dry prematurely, or it might be unable to reach the tip. The complex design of a pen, combined with the stringent demands of its function, makes it vulnerable to manufacturing flaws that can disrupt its intended purpose.

Common Manufacturing Defects in Various Pen Types

The following is a detailed overview of common manufacturing defects across various pen types:

Ballpoint Pens:

Imperfect Ballpoint: The ballpoint itself might be misshapen, have flat spots, or be improperly seated within its housing. This leads to inconsistent ink transfer and skipping.
Clogged Ink Channel: Tiny debris or dried ink can obstruct the channel leading to the ballpoint, preventing ink flow.
Air Bubbles in Ink Cartridge: Air pockets can form within the ink cartridge, disrupting the flow of ink to the ballpoint.
Defective Ball Housing: The housing that holds the ballpoint might be improperly formed, preventing the ball from rotating freely.

Gel Pens:

Inconsistent Gel Consistency: The gel ink might be too thick or too thin, causing it to either clog the tip or bleed excessively.
Blocked Ink Flow: Small particles or dried gel can block the narrow ink channel.
Manufacturing Debris: Residue from the manufacturing process can remain in the pen, interfering with ink flow.
Improper Seal on Cartridge: An imperfect seal can cause the gel ink to dry out prematurely.

Fountain Pens:

Misaligned Nib Tines: The tines of the nib (the writing tip) might be misaligned, preventing proper ink flow.
Baby’s Bottom: The nib’s tipping material might be polished too much, creating a smooth surface that doesn’t grip the paper, leading to ink starvation.
Cracked Feed: The feed, which regulates ink flow to the nib, might be cracked, causing ink leaks or insufficient ink supply.
Defective Ink Sac or Converter: Issues with the ink sac (in older models) or the converter (in modern pens) can prevent the pen from drawing or delivering ink.
Improperly Assembled Nib Unit: The nib, feed, and section might not be correctly assembled, disrupting ink flow.

Guide to Identifying Manufacturing Defects

Here’s a step-by-step guide to help you identify potential manufacturing defects in your pen:

Visual Inspection: Examine the pen’s exterior for any obvious flaws, such as cracks in the barrel, loose components, or signs of leakage.
Ballpoint Examination (for ballpoint and gel pens): Carefully examine the ballpoint tip under magnification (a magnifying glass or a jeweler’s loupe is ideal). Look for any imperfections in the ball, such as flat spots, irregularities, or debris.
Ink Cartridge Inspection: Remove the ink cartridge and inspect it for any cracks, leaks, or air bubbles. Observe the ink level to ensure it is adequate.
Ink Flow Test: Try writing with the pen on a piece of paper. Observe the ink flow. Are there skips? Is the line inconsistent? Does the ink flow stop entirely?
Nib Alignment Check (for fountain pens): Hold the fountain pen so that the nib is visible. Check that the tines are aligned and evenly spaced. Use a loupe if possible.
Feed Examination (for fountain pens): Inspect the feed (the part beneath the nib) for any cracks or blockages. Ensure that the ink channels are clear.
Try Different Paper: Test the pen on various types of paper. Some defects only become apparent on certain paper types.
Comparison Test: If you have another pen of the same type and model that works, compare the performance and the components (e.g., the ballpoint) of the non-functioning pen to the working one.
