• Do not throw a toner cartridge into a fire. Toner may fly and cause burns.
• Store toner cartridges out of reach of small children.
• If a toner cartridge is stored upright, the toner may harden and become unusable. Always store toner cartridges on their side.
• If a toner cartridge other than a SHARP-recommended toner cartridge is used, the machine may not attain full quality and
performance and there is a risk of damage to the machine. Be sure to use a SHARP-recommended toner cartridge.
• Be sure to install four toner cartridges (Y/M/C/Bk).
• If any one of the toner colors runs out, color printing will no longer be possible.
If the Y, M, or C toners run out but a quantity of Bk toner still remains, printing is performed in black and white.
• Depending on your conditions of use, the color may become light or the image blurred.
• Your service technician will collect used toner cartridges.
• To view the approximate amount of toner remaining (indicated in %), hold down the [Home Screen] key during printing or in
standby mode. When the percentage falls to "25-0%", keep a toner cartridge for replacement purposes before toner runs out.
• When toner runs out while the home screen is displayed, the "Toner Empty" message appears in the upper right corner of the screen.
Slowly insert the new toner cartridge
on the level.
Push the cartridge in until it locks
securely in place.
Close the toner cover.
After the toner cartridge is replaced, the machine
automatically enters image adjustment mode. Do not open
the front cover while this is taking place.
