Resolving Stain Problems in Laser Printer Images

What happens when a toner image appears on a laser printer?

A: (1) Turn off the printer, take out the toner cartridge, and shake it left and right to evenly distribute the toner.
(2) Wipe the paper path inside the printer with a dry, clean, soft cloth to remove the toner left in the paper path.
(3) Print a three-page document with only one word to clean the internal parts of the printer.
(4) Select high-quality printing paper.
(5) If there are still problems, you may need to replace the cartridge or imaging cartridge. Or contact the maintenance department.
