Printer prints over a line

In inkjet printers, the print head chips can be mechanically damaged or affected by ink. Additionally, in SNHR inkjets like Canon, HP, and Epson, air can enter and form a blockage, which prevents the normal flow of ink. Similar issues can arise when the dye supply tube (loop) becomes bent.

Laser printers, on the other hand, have a greater number of structural elements that are susceptible to damage, including:

• photo and magnetic shafts;
• the cleaning blade;
• waste toner hopper;
• cartridge counter and chip;
• contacts.

Driver reinstallation

If none of the previous solutions have worked, it may be worth trying to reinstall the driver as well. Sometimes, using an old version of the driver can cause issues such as the inability to print text. You can find the support and downloads section on the website of the printer manufacturer.

Make sure to choose a file package that is specifically designed for your printer model, operating system, and bit rate. This information is usually indicated next to each driver. Once you have downloaded the file, follow these instructions:

1. Extract the "drivers" archive to one of your computer’s disks.
2. Access the "Device Manager" from the control panel on your PC.
3. Locate the printer you need in the list.
4. Select it by clicking on it with the mouse.
5. Click on the "Update Drivers" icon at the top.
6. In the window that appears, choose the second option for manual installation.
7. Please indicate the precise path for the extracted bundle.

The primary cause for a printer to produce streaks on the printed page is typically the cartridge, where components may become worn out, run out of ink, or not be properly refilled. At times, it may be necessary to troubleshoot the printing device or simply take preventive measures.

The Troubleshooter that comes with the system will help resolve common issues that occur when attempting to print a document. It is recommended to utilize this feature as a first step in troubleshooting to address these typical failures.

1. To access the Settings app, simply click on its icon located in the Start Menu.

Navigate to the menu labeled "Update and Security".

Click on the menu on the left and choose the "Troubleshooting" category.

Locate the "Printer" option from the list of troubleshooters and select it.

Clicking on the "Run Troubleshooter" button is necessary.

Printing on Windows can be a hassle, but don’t worry – we’ve got you covered. With this handy guide, you’ll be able to troubleshoot any printer issues and ensure smooth printing. We’ll walk you through the process of checking services and adjusting settings to optimize your printing experience.

Once the complete list of installed hardware appears, locate the troublesome device, give it special emphasis, and proceed to the next instruction.

Scanning of the chosen device is currently in progress and will be completed in less than a minute. The outcome of the scan will be shown on the screen afterwards. If any necessary adjustments can be made, please confirm the action and proceed to attempt printing on this particular printer once more.

If there is no change in the printer’s performance, the procedure may not be effective, so it is advisable to try the following methods.

Here are some ways to resolve the issue:

The problem may be due to inadequate sealing of the cartridge. This is often the case after the cartridge has been refilled. To check if the sealing is compromised, remove the cartridge from the device and swipe it across a white piece of paper. If there is ink residue on the paper, it means that the sealing is broken. You will need to take the cartridge to a repair shop to have it fixed.

Another possible cause is running out of toner. If this happens, the printer may not print any lines. In such cases, simply refilling the cartridge should solve the problem.

If the hopper for residual ink is overfilled, it can lead to issues as well. The solution is to clean the hopper. It is important to perform this procedure every time the cartridge is refilled.

Encoder contamination could also be a potential problem. The encoder is a translucent film with markings that is located along the carriage. If it becomes dirty or contaminated, it can affect the printing process. Cleaning the encoder should address this issue.

To eliminate dirt, simply open the case cover and delicately wipe the encoder with a lint-free cloth that has been dampened with a cleaning compound. Afterward, give it some time to dry, and the device will be ready for operation. In the event that the magnetic shaft has been deformed or has become obstructed by a foreign object, additional measures will need to be taken.

If the printer is printing across the line, it could indicate the presence of a foreign object (such as a paper clip, piece of paper, or scotch tape) on the shaft. To resolve this issue, you will need to remove the foreign object. If the magnetic shaft is deformed, it will need to be replaced. Another possible cause is wear and tear on the photobarrel, which will require replacing the part as the drum’s photosensitive layer wears out over time. Additionally, the toner dispenser blade may not be properly fixed, which can sometimes result in gaps in the printing. It should be examined and repaired if necessary. Lastly, there could be a break in the contact between the magnetic shaft and the drum. In this case, cleaning the shaft contacts and other components will be necessary. If these steps do not produce the desired result, replacement of the components with new ones will be necessary.

Often, this unfortunate occurrence takes place at the most inconvenient moment – precisely when you must rapidly produce a critical document. Yesterday, the printer, which had been functioning perfectly, abruptly decides to shirk its responsibilities: in lieu of the document, it ejects empty sheets of paper or flashes aimlessly as if it fails to comprehend your intentions.

Most people who frequently use a printer experience issues when it comes to printing. The largest category of these issues includes different flaws in the printed image, followed by a complete absence of printing. There can be a multitude of reasons why a printer fails to print or produces poor print quality, ranging from incorrect settings in the operating system to the malfunction of the printer device itself.

The simplest options are

Power or connection is disconnected

It is not uncommon for the power supply or connection cord to become disconnected from the PC or laptop. It is important to check these components for continuity and replace them with new ones if necessary. To start, try plugging another electrical device into the outlet to ensure it is functioning properly. Next, disconnect the power cord from the printer and reconnect it.

If you are using a USB cable for connection, make sure it is plugged into the rear connector block on the PC. Consider temporarily replacing it with a different cable. If the device is connected to the network through an ethernet socket, check both the socket and the patch cord. It is also worth checking the quality of the Wi-Fi connection, if applicable.

To start, check if there is any paper in the tray. Then, disconnect the device and inspect for any paper jams. Take a look from underneath, open the front cover, and remove the cartridge. After that, open the back cover.

If you happen to notice any paper residue, carefully remove it from there.

Toner or ink has run out

In certain printer models, a feature is installed that prevents printing when the ink cartridges are empty. This is commonly found in inkjet and laser printers that come with special chips. To get more information on this matter, you should search the internet using the specific model of your printer. Resetting the counters to zero may temporarily resolve the issue and allow printing to resume.

Method 7: Temporarily disable firewall and antivirus

To use this method, it is necessary to have users who are connecting to a printer through a network or printing documents over a local network. As you may be aware, communication between devices involves the use of a port. This port is typically automatically opened by both the standard firewall and any third-party antivirus software that might be installed on the system. However, there are instances where the process fails due to the specific characteristics of the printer model or its drivers. This failure results in the port being blocked, which prevents printing from occurring. In order to confirm whether this is the case, it is advised that you temporarily disable your antivirus and firewall. Please refer to the articles below for step-by-step instructions on how to do this.

Further information can be found in the articles: Disabling Firewall / Antivirus

If you discover that the issue is indeed caused by a port being blocked by the firewall, it is necessary to unblock it by creating exceptions for all relevant ports. We have provided a comprehensive guide on how to do this in another article on our website.

Troubleshooting printing problems in different situations

Stripes appear in different places every time

If your laser printer is producing streaks all over the pages, or if the streaks appear in random spots, the issue is most likely with the cartridge.

Take out the cartridge and ensure that it is tightly sealed.

If toner gets ejected, inspect the seals that secure the toner and ensure that the cartridge itself is undamaged.

If the problem cannot be fixed, replace the cartridge with a new one.

Streaks consist of individual small dots

The issue of cartridge malfunction often arises due to incorrect refill procedure, such as when the waste toner filling exceeds the capacity of the hopper or when the metering blade is not properly installed (this blade regulates the amount of toner that reaches the magnetic roller).

To rectify the problem, it is necessary to refill the cartridge correctly, adjust the blade to its appropriate position, and clean the hopper.

When encountering streaks while printing with an HP or Canon cartridge, it is not advisable to attempt refilling or ponder why these streaks occur. Rather, it is recommended to simply replace the cartridge, as their quality is not up to par.

Unprinted streaks anywhere on the paper

It is a more frequent occurrence when the printer shaft is obstructed due to the depletion of toner or the presence of foreign objects like paper clips, screws, or hardened toner. The resolution for this issue involves refilling the toner.

A wavy or intermittent streak is located at the edges of the sheet on one or both sides of the paper

This issue occurs when the image drum becomes worn or sustains damage.

The image drum is a cylindrical component that is coated with a photosensitive varnish layer. Prior to printing, a laser illuminates specific areas on the photodrum where the magnetic roller transfers toner.

Over time, the photosensitive layer can wear off along the paper’s edges. When this occurs, it is necessary to replace the drum.

There is a misconception that Epson printers start experiencing these streaks after 3-5 years, but in reality, printers of any brand can be susceptible to this type of malfunction.

Horizontal stripes at equal distance from each other

A defect like this arises when there is insufficient contact between the photobarrel and the magnetic shaft. This can occur due to toner spillage or overfilling of the toner waste hopper.

Typically, this issue is caused by subpar cartridge refilling practices. In some cases, wear and tear of the printing mechanism components (such as the photobarrel, shaft, or rakel – a drum cleaning plate) can also be responsible.

To resolve this problem, you can either refill the cartridge or replace the faulty unit.

Update drivers

Once you have completed all of these steps and your printer is still printing gibberish, the next course of action is to update your printer drivers. It is possible that during the process, you may have installed software that is conflicting with your printer drivers. To address this issue, you will need to download the most up-to-date drivers from the manufacturer’s website and attempt to update them. There are two options you can choose from:

1. Uninstall all existing printer drivers on your computer and install a new one
2. Update the drivers without uninstalling the current ones

Completely uninstalling the printer drivers in Windows

If you are looking to remove all drivers from your computer running Windows 10 or Windows 7, follow these steps:

1. First, stop the print service by opening a command prompt and entering the following command: net stop spooler
2. Next, navigate to the C:\Windows\system32\spool\drivers directory and delete all subfolders and files from the x64 and W32X86 directories. This will remove all printer drivers that are installed on your computer.
3. Once the deletion is complete, restart the print service by entering the command "start spooler" in the command prompt.
4. After that, visit the manufacturer’s website to download and install the latest drivers for your printer.
5. Finally, perform a test print to ensure that everything is working properly.

To resolve issues with hieroglyphs or strange characters when printing on printers such as Kyocera, HP, Brother, Canon, Epson, etc. and address questions like "Why is my printer printing strange characters?", "Why does my printer print nonsense?", and "Why does my printer print a different font?", you can try reinstalling the drivers using the following method:

1. First, download the latest drivers from the manufacturer’s website. Make sure to unzip the downloaded file.
2. Next, navigate to the printer properties and click on the Advanced tab.
3. Click on the Change button and follow the provided steps. At one point, you’ll need to select the folder where you unzipped the downloaded file.
4. Once you’ve done that, you should see a new item with the driver in the list. Select it and click on the Apply and Ok buttons.
5. That’s it! Give it a try and see if the issue is resolved.

Problems with cartridges, dye, SNHRs

Every dye, whether it is a toner or ink, will eventually run out. However, this depletion does not occur suddenly. The signs that there is only a small amount of dye left include a decrease in print quality, such as pale colors, whitish streaks, and incomplete printing. Sometimes, the printer may even stop printing even if there is still a normal level of dye in the cartridge. This can happen due to several reasons:

• An ink droplet has become dry in the print head or is blocked by an air lock.
• The cartridge has been installed incorrectly, for example, with protective films still in place or with the cover not fully closed.
• The cartridge air ducts have become contaminated.
• The ink loop of the non-impact printer cartridge has become overcrimped or clogged.
• A non-original cartridge has become blocked.
• The maximum number of printouts has been reached.
• The cartridge is malfunctioning.

HP offers a cartridge cleaning service.

• Epson: performing print head cleaning.
• Canon: offering both cleaning and deep cleaning services (the latter being an upgraded version in case the former doesn’t yield satisfactory results), and more.

While conducting the cleaning process, a specialized pump situated inside the printer applies significant pressure to expel ink through the nozzles. This effectively resolves any issues arising from ink clots or air locks.

The printer models that have the lowest cost do not come with a pump, which means that the nozzle cleaning function does not work on them, even if the driver supports it. If there is a blockage, the printheads of these devices need to be soaked and rinsed in cleaning fluid.

If you have removed the cartridges from the printer, ensure that they are installed correctly and that their air ducts are not obstructed.

If you are using an SNHR, you should also check if the ink loop is clear and if the air holes of the tanks are not blocked.

When printing on a laser or LED printer and you notice spots and streaks (sometimes resulting in almost black sheets), it could be due to cartridge leaks, overfilling of the hopper-waste hopper, foreign small objects inside the device, damage, improper installation, or wearing of cartridge parts.

You may encounter problems after refilling when:

• The print appears faint even with a full cartridge;
• The image shows multi-colored spots instead;

These issues are usually caused by contamination, incorrect installation of the cartridge, or improper refilling techniques.

If you experience a complete absence of the image (white sheets) or printing defects after replacing the original cartridge or using a different type, it is likely due to incompatibility with your printer model. In some cases, re-flashing the cartridges or the device can solve the issue, while in others, only purchasing original components and consumables will fix the problem.

Problems with paper

Incorrect setup

For proper installation, it is essential to ensure that the paper in the printer tray is completely level. Start by removing all the sheets from the tray and manually aligning them. Additionally, make sure to adjust the sliders located inside the tray so that the paper of the desired size fits comfortably. Once the paper is in place, firmly slide the sliders towards the edges, applying gentle pressure without exerting excessive force.

Quality

The issue of irregular printing arises due to the substandard paper utilized. If you’ve recently switched to purchasing products from a different manufacturer, chances are high that this could be the root cause. Locate a package from the previous manufacturer and ascertain the quality parameters, then compare them to the characteristics of the new products. Experiment with printing using sheets from an alternative production. Moving forward, aim to procure goods from reputable companies that have had no prior issues.

When it comes to photo printing, the selection of paper type holds even greater significance. This aspect can and should be specified in the printer’s settings. Begin by opening the desired document or picture for printing. Then, press CTRL+P and click on the Properties button to select the suitable paper type. Alternatively, it is possible that your printer might not be compatible with the photo paper you have purchased.

Reasons why the printer does not print some lines and their solutions

Contained within this document are all the primary potential causes as to why the printer is failing to print certain sections of text or particular lines. Additionally, this malfunction presents itself in the form of skipping or printing over a line. Our guide will aid you in swiftly identifying the reason behind this occurrence and offer assistance in resolving the issue yourself, even if you lack experience in repairing office equipment.

These recommendations are applicable to any model of device from HP, Canon, Epson, and others. It should be noted that this problem is more problematic for devices that employ the inkjet method of printing. Troubles with laser printers are less frequent.

Problems with software

For trouble-free printing, certain conditions must be met by the computer.

1. The "Print Manager" service needs to be active.
2. It is necessary to install the printer driver. Ideally, install all programs and drivers provided by the manufacturer.
3. The computer must be clean and free from viruses, as there is a risk of damaging the drivers.
4. Restart the Print Manager. Press "Windows+R", run the command "services.msc". Find the desired service in the list. Right-click and choose "Restart".
5. Perform a complete driver reinstallation. It is recommended to completely uninstall the printer and its driver from Windows first. Then proceed with the installation again.

Magnetic Shaft Damage

The functioning of the toner and the printing process rely on the magnetic shaft, which transports the toner to the image drum.

The surface of the top toner may appear smooth, but its abrasive particles can actually cause damage to the magnetic shaft over time, leading to deterioration.

It is easy to determine if the shaft is worn out by observing the following indications:

• Presence of white voids with stripes or, conversely, unattractive blotches;
• Printing that is excessively "transparent";
• Text filling in unevenly and unevenly;
• Appearance of wavy streaks that run horizontally across the page.

If the cause of poor printing lies in the performance of the roll, what should you do? Simply purchase a new one, as repairing it would be comparable to buying another device.

When using a laser printer, if you notice random vertical stripes on your printed pages, it is likely a result of a common issue – a leaky cartridge. Take a close look at the rubber gaskets that are supposed to prevent toner from spilling out. If you discover any cracks, it means that the cartridge is unusable and should be replaced. This type of damage is quite common after an incorrect refill of the cartridge.

The waste hopper is full

Inside the cartridge, there is a unique blade known as a rakel.

It eradicates the unused toner present in the printer. The toner is always disposed in a separate container known as a waste hopper to prevent blockage of the encoder ribbon and drum.

However, at times, the waste hopper becomes too large, causing excess toner to spill. When this occurs, a broad gray strip appears on either the left or right side of the printed sheet.

To clean the waste hopper, some disassembling of the cartridge is required. Unscrew all the screws, approximately 8 to 9, found on both sides of the component and remove the top cover. Underneath, you will come across the magnetic shaft and located behind it will be the waste hopper. Your objective is to detach the screws from the rocker and cleanse it using a regular, non-abrasive cleanser.

After removing the blade, shake off any excess toner from the waste hopper and gently wipe the bottom with a soft cloth.

Consequently, inkjet or laser printers may produce striped prints due to a range of factors, from something as simple as running out of ink to a more severe issue like a damaged image drum or magnetic shaft.

When troubleshooting this problem, it is crucial to identify the cause of the streaks and take appropriate action depending on the type of printer.
