Hi! 

I have following issue with my HP LaserJet MFP M426fdn.

Whenever a new page is printed, there are black stripes on the left side of the page (see attached file).

I already checked the catridge and printed several cleaning pages. What else could I try?

Looks like a defective toner to me.

 

Measure distance between 2 stripes and compare.

Thank you for the reply. Seems to be the primary charging roller. Is there any way for me to fix this without getting a new toner?

You will need new toner cartridge.
