Printer Printing White Lines? How to Fix It (2026)

Your printer printing White lines while spitting them out on a page with thin white stripes across the text. The document looks ruined, but the fix is usually quick: most cases take under 15 minutes to solve.

This guide lists the main causes and walks you through the fixes in order, from easiest to hardest. It also covers two related issues: banding and garbled characters. Let’s break it down.

What Causes White Lines on Printed Pages

White lines appear when ink or toner fails to reach part of the page. Something blocks the flow, and the printer skips a strip. The usual suspects:

• Clogged printhead nozzles. Dried ink blocks one or more nozzles. This is the top cause on inkjet printers, especially ones that sit unused for weeks.
• Low or empty ink or toner. A cartridge running dry prints faint output with white gaps.
• Dirty rollers. Dust or ink buildup on feed rollers can smear or skip, leaving streaks.
• Wrong paper or driver settings. The wrong paper type in the print dialog changes how the printer lays down ink.
• A failing cartridge or drum. On laser printers, a worn drum leaves repeating white lines at regular intervals.

Narrow it down with a test page. Lines in the same spot on every page point to the cartridge, drum, or a roller. Lines that move around point to nozzles or settings. If the defect shows on your screen instead of on paper, see our guide on fixing a dead pixel on a laptop.

Fix 1: Run the Printhead Cleaning Cycle

For inkjet printers, start here. Every inkjet has a built-in cleaning cycle that forces ink through the nozzles to clear clogs. Here’s the fix.

1. On Windows, go to Settings, then Bluetooth and devices, then Printers and scanners. Click your printer, then Printing preferences.
2. Open the Maintenance or Tools tab and click Head Cleaning or Nozzle Cleaning.
3. Run one cycle, then print a nozzle check pattern to see the result.
4. If lines remain, run a second cycle. Stop after two or three: cleaning burns through ink fast.

You can also start cleaning from the printer’s own screen, usually under Setup, then Maintenance.

Fix 2: Print a Nozzle Check Pattern

A nozzle check pattern prints a small grid, one line per nozzle, and shows exactly which nozzles are blocked. Look for gaps or missing segments.

If the pattern prints clean, your printhead is fine. If gaps persist after two or three cycles, move on to the cartridge fixes below.

Fix 3: Check Ink and Toner Levels

Low ink is the simplest cause and the easiest to overlook. Check each cartridge in the printer software or on the printer’s display.

• Replace nearly empty cartridges. A cartridge at 5 percent can already cause gaps.
• Reseat the cartridges. Pull each one out and push it back in until it clicks.
• Shake toner cartridges. On laser printers, rock the cartridge gently side to side to redistribute the toner.
• Suspect cheap refills. If white lines started right after a refill, the cartridge is your prime suspect.

Fix 4: Clean the Paper Path and Rollers

Dust, paper bits, and dried ink collect inside the printer. Turn the printer off and unplug it first.

1. Open the paper tray and any rear access panels. Remove jammed or curled paper.
2. Dampen a lint-free cloth with distilled water and wipe the feed rollers gently, turning them as you go.
3. Check for torn paper scraps inside. Even a small piece can lift the paper and cause a stripe.
4. Let everything dry, close the panels, and print a test page.

Skip alcohol-based cleaners on rubber rollers. They dry out the rubber and make feeding worse. For a full cleaning routine, our printer maintenance tips guide covers schedules that prevent most print quality issues.

Fix 5: Check Driver and Paper Settings

Wrong settings can mimic a hardware fault. Check these in the print dialog:

• Paper type. If you loaded plain paper but the driver thinks it is glossy photo paper, the printer lays down the wrong amount of ink.
• Print quality. Draft mode skips dots to save ink, which can look like white lines. Switch to Normal or Best.
• Paper size. A mismatch between the document size and the tray size can create blank bands.
• Driver version. Install the latest driver for your exact model from the manufacturer’s site.

Related Issues: Banding and Garbled Characters

Banding is a close cousin of white lines. Instead of thin stripes, you get wider bands of wrong color or brightness, usually in photos. Run printhead alignment from the Maintenance tab, since misaligned heads print color bands. Also turn off high-speed printing in the driver. If banding repeats at regular intervals on a laser printer, the drum is worn.

Garbled characters are a different beast. Pages of random symbols point to a communication problem, not an ink problem. Reinstall the latest driver, try a different USB cable, and clear the printer queue with our Windows 11 walkthrough. If a plain test page prints fine, the file or app is at fault.

When to Replace Parts Instead of Cleaning

Cleaning fixes clogs, not worn parts. Replace the drum when the same white line repeats at exact intervals on every page. Replace the printhead when gaps persist after three cleaning cycles and a fresh cartridge. If either part costs more than half the price of a new printer, buy a new printer instead.

Frequently Asked Questions

Why is my printer printing white lines all of a sudden?

A clogged printhead nozzle or a low cartridge is the usual cause. Run a nozzle check pattern first. If it shows gaps, run the printhead cleaning cycle once or twice.

How many times can I run printhead cleaning?

Two or three cycles is the limit. Each cycle uses a lot of ink. If three cycles do not fix the gaps, the cartridge or printhead is likely bad.

Can low ink cause white lines even if the printer says ink remains?

Yes. Level readings are estimates. Swap in a fresh cartridge and test again.

What is the difference between white lines and banding?

White lines are thin unprinted stripes from blocked nozzles or low ink. Banding is wider stripes of wrong color or brightness from misaligned printheads or wrong paper profiles.

Why does my printer print garbled characters?

Garbled output usually comes from a corrupted driver or a bad USB cable. Reinstall the latest driver, try a different cable, and clear the print queue.

Should I repair my printer or buy a new one?

If a new drum or printhead costs more than half the price of a comparable new printer, replacing the printer is the smarter move.
