# Printer Printing With Lines? 7 Causes and How to Fix Them  When you are experiencing problems with your printer but only see lines or streaks on your prints, it can be irritating. There are any number of reasons a printer with lines might have a clogged printhead or a component that is damaged. Once you know the cause, you can decide whether to do a cleaning or have the job professionally repaired. Let's take a look at 7 of the most common **[causes of printer lines and how you can solve them](https://devicefixes.com/blog/how-to-fix-printer-streaks/)**. ## Printer Lines Causes and Solutions ### 1. Clogged or Dirty Print Head One of the most common reasons for printer streaking is a clogged or dirty print head. Dried ink may clog the small nozzles used to transfer ink to the paper, causing some parts of the print to be blanked out, printed horizontally, or to be uneven. **How to fix it**: Use the print-head/ nozzle cleaning feature of your printer. The process may have to be repeated once or twice. Don't overclean, as it can use up a lot of ink. ### 2. Inadequate or uneven ink level. When low ink levels are detected, the printer will print in a faded tone and print white streaks, especially when one color is low. If the printer's cartridge is not evenly distributing the ink, it can cause issues with the printed text or images, too. **How to fix it**: Verify that the ink is not depleted and replace empty or low ink cartridges. Ensure that replacement cartridges are properly installed. ### 3. Toner/Drum Issues Lines can form on laser printers due to toner cartridge or imaging drum dirt, wear, or damage. Lines or streaks on the same page of every book may be a component problem. **How to fix it**: If applicable, take out and put in the toner cartridge. Look for any obvious signs of toners and damage. If the drum is worn, then it might require repair. ### 4. Dirty Printer Components If dust, dried ink, toner residue, or paper debris remain in the printer, they can disrupt the printing process and cause white lines to appear on printed documents. **How to fix it**: Shut off and unplug the printer before carefully cleaning the accessible areas, following the manufacturer's instructions. Avoid applying too much liquid or pressure to fragile parts. ### 5. Incorrect Print Settings Lines can be caused by a hardware issue, but not always. Sometimes, the ink or toner application may be impacted by incorrect quality, paper type, or print-mode settings. **How to fix it**: When printing, go to your printer settings and choose a different paper type and a higher print quality setting. Look out for draft or economy mode as well. ### 6. Low Quality or Wet Paper Damp, damaged, or wrinkled paper can cause spills and streaks. **How to fix it**: Have a clean, dry piece of paper recommended for your printer. Keep unused paper in a dry place and change curled, damp, or damaged paper. ### 7. Worn or Damaged Printer Hardware If after cleaning, changing cartridges, and making settings, the problem persists, the printer may have a mechanical or electronic defect. Sometimes printer streaking is a sign of a damaged print head, drum, roller, or other internal parts. **How to fix it**: After normal troubleshooting, if the problem persists, a diagnosis by professionals may be required. Do not disassemble internal parts unless you are familiar with the service procedures of your printer. ## Find out when to seek printer repair services. Sometimes the solution to printer streaks lies in knowing how to do it, and sometimes it does not and needs professional help. Checking your printer can help you determine what the issue is if you've tried to clean it and replaced the cartridges, but it still produces streaks.
