Question about Lexmark Office Equipment & Supplies
Vertical rows of black dots print along right side of page, even after installing new Lexmark (refurbished) print cartridge. I'll appreciate any advice on resolving this issue. Thank you.
That usually indicates a worn heat roller in the fuser assembly. You can get a fuser from Amazon or other online site. They are user replaceable and run about $80-100. Do a search for T620 fuser and you will find them. Part number 99a2402 What happens is the Teflon coating on the fuser wears down which allows the toner to stick where is should not stick so it gets deposited on the paper in other locations and leaves spots.

Did you carefully inspect all through the paper path for some fuzz, or a small piece of paper smearing the print?
The other issue would be the fuser. Do you see any reprinting of images or letters in that area?
What you can do is set the machine to print 2 or more pages and open a cover or turn off the power to jam the prints in the machine. See if the line is on the drum or not. If not then you have a fuser roller issue which would require replacing the fuser.

check the "photoconductor unit" (pg 37 in the Maintance manual)
ours was doing it with the magenta and saw a faint 'scratch' on the roller. will attempt to replace and report back if this fixes it.
