How do you clean a laser printer?

Answer by  spaffman10000 (469)

The transfer roller is probably shot. In most laser printers, this is part of the process unit which you swap out when changing the toner, so a new cartridge ought to fix this problem. As a last resort you can try wiping it with a soft clean cloth, but in all likelihood you will make the print quality even worse.

Try recalibrating by pulling out the ink cartridges and reinserting them. It should recalibrate on its own. Also, wipe the terminal of the black cartridge; could be gummed up.

You should refer to the manual that came with your printer, or access the software that you have installed in your computer. Many printers have an option in their included software that automatically cleans them and gives you optimum printing quality.
