Hello, I am having an issue with errant lines/marks on pages I print. Photos attached.

 

This happened after I replaced the yellow toner cartridge and it was defective (leaking yellow toner). I replaced it with a new cartridge HP sent me under warranty - now the printer is printing fine except for the marks on each page. The toners are all HP OEM / original cartridges (not remanufactured).

 

I have done the printer "Clean" process at least 10x, the marks are not effected at all. I have restarted the printer with no change to the marks.

 

Any tips on how I can clear this up?

 

Thank you, Gina

Measure the distance between defects as this distance will tell us which component is causing the problem. I am in the field right now and have no access to those charts.

Hello, the distance between the mark lines is 1".  The larger mark shown in the 3rd photo only comes every 2-3 pages.

Also, I just noticed the 3rd photo I uploaded with the original post did not show up.  Here it is.  This mark only appears every 2-3 pages.20200730_105657.jpg

And hopefully, 3rd try is the charm.  LOLInked20200730_105657_LI.jpg

Hi Repairatrooper (or anyone else), any further advice?  No one else has responded.

 

Yesterday I slid out the toner drawer and used an aircan and blew off each toner cartridge and also inside the machine.  It made no difference in the issue.

 

Thank you,

Gina
