To obtain the best “yield” from your high-capacity toner cartridge in the event that
printed output appears faded:
First Instance: remove the toner cartridge and shake it a
few times to evenly distribute the toner powder.
Re-install the cartridge and continue printing.
Second Instance: In the event that fading occurs again,
repeat the above process.
Finally: When the on-screen display indicates toner out, or if print appears faded for a
third instance, the toner cartridge needs to be replaced. Install a new high-capacity
toner cartridge.
