Why is My Printer Streaking: How to Fix It

Printer streaks are one of the common technical issues that printers face during printing. It might cause due to clogged nozzles, dirt on the print head, low toner levels, or damaged drums. 

Printer streaks are generally characterized by lines, smears, and bands of lightness on printed pages, making you worried about how to fix printer streaks. 

Fortunately, for most of the cases that can cause printer white streaks, do-it-yourself troubleshooting can provide a solution. 

Here’s a quick troubleshooting and repair procedure to help resolve the problem, depending on whether the affected printer is an inkjet or laser printer. 

What Do Printer Streaks Look Like? 

Printer streaks may appear as:

•  Running vertically from top to bottom
•  A series of horizontal bands across the page
•  Smudges and/or residual toner from the print head
•  Missing or light areas of either black or color on the page
•  Marks that are repeated at regular intervals on the page. 

Printer streaks are caused by factors related to different types of printer technologies. 

Common Causes of Printer Streaking 

Several issues can lead to your printer with lines, producing substandard quality printed output. Printer streaking may appear due to the following causes

• Clogged Print Head:   Dried ink accumulates and blocks the very small ink delivery nozzles in inkjet printers, creating a missing line or faded line when printing. 
• Low or Empty Ink Cartridges:  The lack of adequate amounts of ink within an inkjet printer will limit that printer’s ability to provide a consistent delivery of ink to its print head. Thus, prints are rendered/completed in a lighter shade than they are intended. 
• Dirty Printer Rollers:  If your printer’s rollers become dusty or there’s too much build-up of paper particles or ink, then you may notice smudged or streaked marks on all your prints.
• Misaligned Print Heads:   If your printer’s printheads aren’t properly aligned, then the ink may be placed incorrectly, which will create blurred or fuzzy text and lines.
• Low-Level or Leaking Toner Cartridges: Insufficient or leaking toner in laser printers can produce faded prints, black lines, or scattered marks.

Quick Fixes to Try 

You might be struggling to know how to fix printer streaks. Here are some common  fixes that you can try for any kind of printer 

• Run your printer’s cleaning cycle:   Most printers will have a cleaning feature built into them, which will help to remove dried ink or other debris that may have accumulated on the print heads and improve print quality.
• Check the levels of your ink or toner cartridges:   Low levels of ink or toner will cause faded lines and streaks, so replace them if they are almost empty.
• Print a test page: When troubleshooting, printing a test page will help determine whether or not the issue is being caused by a particular colour, cartridge, or printer component.
• Power the printer off/on: Turning the power off/on to the printer will clear temporary errors and reset the printing system.
• Clean the rollers with a damp cloth: Use a clean cloth to wipe down the printer rollers to eliminate dust, fibre from previously printed paper, and ink to enhance print quality.

When to Replace Your Printer Toner or Ink 

If You Have Printer Streaking Problems, there are cases when printer streaking gets a new cartridge, but in several cases, there are signs that can help you determine if you need to replace the cartridge.

Replace toners/ink cartridges if:

• The printout is faded or lacks color.  If the print head alignment and cleaning do not solve your printing issues, the cartridges could be out of ink or dry.
• You received a notification that the printer had a low-ink condition. Most printers send you a low-ink indicator when the ink is nearly exhausted.
• If there are persistent streaks/gaps in the print. Persistent streaks/gaps indicate that the cartridges cannot supply ink properly.
• The toner/ink cartridges are old or dry. Ink cartridges become dry after a long period without usage.

Fixes for Inkjet Printers

If you are using an Inkjet Printer, then here is how to fix printer streaks, 

• Execute the print head cleaning cycle:  Use the built-in print head cleaning function on the printer to remove dried ink build-up and clear the clogged print head nozzles.
• Check/replace low ink cartridges: If your ink cartridge level is low, or if your cartridges are old and have dried out, replace them with new cartridges.
• Align the print heads: Perform print head alignment when you have blurry or misaligned text, and when you have an unevenly printed image.
• Clean the print heads manually: If the automatic print head cleaning cycle doesn’t resolve the problem, manually clean the print heads using a lint-free cloth and distilled water.
• Clean the paper feeder rollers: Dust and debris can build up on paper feeding rollers and lead to smudges and streaks on the printed image. Remove and clean all dust and paper contamination from the paper feeding rollers.

Fixes for Laser Jet Printers

When a laser printer produces printed output with areas that are excessively “light,” “dark,” “streaked,” or “missing,” there are several steps a user can perform in order to clear these types of issues. Below are some steps the average user can employ in an effort to restore their laser printer’s performance:

• Change the Toner:  Attempt to redistribute the toner by removing and gently shaking the toner cartridge.
• Replace any low or empty toner cartridges:  The printing output is still “light,” “dark,” or “streaked” after you have removed and shaken the toner cartridge.
• Clean the drum unit:  Remove debris and excess toner that has collected on the drum unit to decrease the number of lines and duplicate marks that appear on the printed output.
• Inspect the printer for evidence of ink/toner leaks:  If you find any ink or toner stains or leaks from your cartridges, immediately replace them.
• Clean the transfer roller:  Dust and excess toner that accumulates on this component may also cause the printer to produce streaked prints; clean it properly.

Fixes for Label & Thermal Printers

If you are using a Label & Thermal Printer, then here is how to fix printer streaks 

• Maintain the Printhead Clean: Accumulation of dust, adhesive residue, or paper fibers can result in fading or streaking issues. Cleaning the printhead regularly using a cleaning pen or isopropyl alcohol will help prolong its use.
• Replace Worn Printheads: If you have irreparable streaking issues, the thermal printhead must be replaced. 
• Adjusting darkness of print: If the prints are light or not evenly printed, adjust the density and/or temperature setting to better match the label you are printing on.
• Reduce print speed: Printing too fast can lead to incomplete image transfer. Slowing down printing speed usually results in improved print quality.
• Clean the platen roller: If dirt or adhesive has built up on the roller, it can leave lines on the printed images and lead to uneven prints. Use a lint-free cloth and an approved cleaner to clean the platen roller.

Still Streaking: Time to Call a Technician

If you have tried these steps and your printer printing lines, you may need to call a professional printer repair service. In that case, you should also consider calling a technician when:

•  You have replaced the toner cartridges and cleaned the printer multiple times, yet your printed output still contains streaks.
• The printer produces the same printed output each time you print, regardless of the paper type or print media.
• You hear unusual noises, grinding noises (indicative of a paper jam), and/or the paper jam occurs on every print job.
• The drum unit, print head, and/or fuser assembly are obviously damaged.
• The printer displays an error message indicating a hardware or maintenance problem.
• You have discovered toner or ink leaking onto the inside of the laser printer.

If you are working with multiple printers for your office, then don’t let the printer slow down your assignments. Call a technician and get your printer working properly.

Wrap Up

Streaked prints can be annoying; however, most of the time, they are simple to fix by doing some troubleshooting. Most streaked print problems are caused by a clogged print head, low ink or toner, dirty rollers, or a worn component (drum or fuser). Keeping your printer well-maintained, replacing the toner cartridge when necessary, and using quality paper will keep your printer in good working order and prevent further problems from occurring. Being able to identify the issue early will help get you back to producing professional-looking printed materials and prolong the life of your printer. In this guide, we have got you covered with all the fixes for how to fix printer streaks.
