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.

1Open the front door.

2Pull the toner cartridge out and remove it from the printer.

3Gently shake the toner cartridge from side to side five or six times to redistribute the toner.

NOTE: 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.

8.4 Maintenance

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

4Reinstall 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/ SCX-4521FR, incoming faxes are saved in memory. At this stage, the toner cartridges needs to be replaced.

NOTE: You can set the machine to ignore the “[Toner Empty]” message and to continue printing incoming faxes. See “Ignoring the Toner Empty Message (Only for SCX-4521F/SCX-4521FR)” on page 8.5.

Remove the old toner cartridge and install a new toner cartridge. See “Installing the Toner Cartridge” on page 2.2.
