Black Lines when I print

Laser Jet Pro M118dw
macOS 10.15 Catalina

I keep getting little black lines on the right side of every page I print.  I've replaced the toner cartridge and the printer drum.  Anyone know what this is and how to fix it?

 

Thanks!!

Black Lines when I print

Hi @CHH7

Welcome to the HP Support Community. I'd be happy to assist you.

  • Which application are you trying to print from?
  • Have you tried printing different types of documents like PDF, Word, or Webpages and check if the issue persists?
  • Try making a standalone copy and check if that works. By this, we can conclude if this is a hardware or a driver issue.

For now, let us try these steps:

 

Reset the printer

  1. With the printer turned on, disconnect the power cord from the rear of the printer.
  2. Wait at least 60 seconds.
  3. Reconnect the power cord to the rear of the printer.
  4. Turn ON the printer, if it does not automatically turn on.
  5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Print a cleaning page

  1. On the printer control panel, press the Setup button.

  2. Open Service, and then Cleaning Page.

  3. Load plain letter or A4 size paper when prompted, and then press the OK button.

For more info on resolving print quality issues, refer to this document.

 

If the black line exists on the copy and the cleaning page, this could be a hardware issue.

 

Hope this helps! Keep me posted.

Thank you for the response.  Unfortunately I had to buy a new printer after replacing the toner cartridge and print drum.
