Printer drum destroyed , scratches

[alvar1]

Translated from Swedish with Microsoft Translator

Attaches pictures of tones and transfer belt.
I have found that it is not just software errors.
It's the printer drum on the toner cassettes that's scratchy. Mostly on M and a little on C, where you can see color in the scratches. On K and Y there are small scratches all over the width, but no visible color in the scratches.
On the transfer belt there are a lot of color, but nothing gets transferred to the prints.
A color printout from Word shows the same stripes as from the printer drums. A printout of black text from Word is without errors.
Toner is HP original and all were changed at the same time, 2018-12-18. Could the toner have been defective from the supplier?

Hi @alvar1,

 I'd like to help!

To better assist you - 

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or devices? 

While you respond to that, let's print a Print Quality Diagnostic page -

1. On the printer control panel, press the OK button to open the menus.

2. Press the left or right arrow button () until Reports appears on the control panel display, and then press OK.

3. Press the left or right arrow button () until Diagnostic Page appears on the control panel display, and then press OK.

   The printer prints a diagnostics page.

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix " Print Quality Issues" issue applicable for your printer -  Print Quality Issues 

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.

1. What is copy print out?

2. I think it is all application  when I NOT select greyscale.

When you copy a document on the standalone printer, does the printout have the same print quality issue?

If yes, then it's a hardware issue with the printer.

I'd suggest you contact HP in your region regarding the service options for your printer.

Hope this helps!

Keep me posted!
