Redistributing Toner
When the toner cartridge is near the end of its life, white
streaks or light printing occurs. The LCD displays the warning
message, “[Toner Low]”. You can temporarily reestablish print
quality by redistributing the remaining toner in the cartridge. In
some case, white streaks or light printing still occurs even after
you have redistributed the toner.
1
Open the front door.
2
Pull the toner cartridge out and remove it from the printer.
3
Gently shake the toner cartridge from side to side five or
six times to redistribute the toner.

: If toner gets on your clothing, wipe it off with a dry
cloth and wash clothing in cold water. Hot water sets toner into
fabric.

AUTION
: Do not touch the green underside of the toner
cartridge. Use the handle on the cartridge to avoid touching
this area.

Reinstall the cartridge and close the front door. Make sure
that the cover is securely closed. If it is not firmly closed,
printing error may occur when you print.
Replacing the Toner Cartridge
When the display on the control panel shows the warning
message, “[Toner Empty]” the toner cartridge has run out but
continues printing. For the SCX-4521F, incoming faxes are
saved in memory. At this stage, the toner cartridges needs to
be replaced.

message and to continue printing incoming faxes. See

cartridge. See “Installing the Toner Cartridge” on page 2.2.
