Black Vertical Lines Printing Hp Laserjet 1200 Laser Printer
Chosen Solution My prints have vertical track lines throughout page. How can I tell if the problem is that of the toner or fuser or rollers, etc.? Do an interrupted print, print a job and open the top cover when the paper starts to feed out. Remove the paper and open the cover on the toner cartridge to see the remaining print image, check to see if there are lines that match up with the paper....
