Redistributing the Toner

When toner is low, faded or light areas might appear on a printed page. You might be able to temporarily improve print quality by redistributing the toner. The following procedure might allow you to finish the current print job before replacing the toner cartridge.

1Open the top cover.

2 Remove the toner cartridge from the printer.

WARNING!

Avoid reaching too far into the printer.

The adjacent fusing area might be hot!

Caution

To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.
