Dell 1710/n Mono Laser Printer - Manual (Page 83)

When the Toner low light sequence appears or when you experience faded print, remove the toner
cartridge. Firmly shake it side-to-side and front-to-back several times to redistribute the toner, and then
reinsert it and continue printing. Repeat this procedure multiple times until the print remains faded. When
the print remains faded, replace the toner cartridge.
To replace the toner cartridge:
Open the front cover by pressing the button on the left side of the printer and lowering the cover. 1.
CAUTION: When replacing a toner cartridge, do not leave the new cartridge exposed to
direct light for an extended period of time. Extended light exposure can cause print quality
problems.
