Excess or Leaking Toner

Low-Quality or Damaged Paper

Paper with wrinkles or debris drags toner across the page. In addition, it may scratch internal parts.


How to Fix Black Streaks on Printed Pages


Clean the Printer

Turn off the device. Unplug it. Next, clean the rollers and the paper path with a lint-free cloth.
This step often solves early streaks.


Check Toner and Cartridges

Make sure the cartridges are installed correctly. Also, check for leaks or expiry dates.


Inspect and Replace the Drum

If the same mark repeats often, the drum may be worn. In this case, replacement is the best solution.


Service the Fuser

If streaks remain, the fuser may be damaged. Often, a technician can fix the problem quickly.


Run Printhead Cleaning (Inkjet)

Use the built-in cleaning cycle. Usually, one or two cycles restore normal print quality.


Use Better Paper

Choose smooth, clean, dry paper. Good paper, as a result, prevents many streaks.
