Question about HP LaserJet 2420 Printer
After inserting a new toner cartridge, all print outs are coming out with 6 black dots on the left side of the paper
If the spacing between dots are the same, then you have a dirty or bad roller. If you never had this problem prior to installing the new toner cartridge, then I would suspect you have a bad one. Try a different toner.
