Maintenance

This category describes how to perform routine cleaning operations, and replace toner cartridge.



Cleaning the Machine

If the original is not copied clearly, clean the machine. For high-quality printouts, we recommend cleaning the machine once or twice a month.


Remark
  • Do not use alcohol, benzene, paint thinner, or other solvents for cleaning. Doing so may result in damage to the machine components.
  • Do not use tissue paper, paper towels, or similar materials for cleaning; they can stick to the components or generate static charges.
  • Disconnect the power cord from the power outlet regularly, and clean the area around the base of the power plug's metal pins and the power outlet with a dry cloth to ensure that all dust and grime is removed. If the power cord is connected for a long period of time in a damp, dusty, or smoky location, dust can build up around the power plug and become damp. This may cause a short circuit and result in a fire.
  • You cannot send or receive documents when the main power switch is turned OFF or the power cord is disconnected.
  • If the main power switch is turned OFF, all jobs waiting in the print queue will be erased.
  • Documents received into memory and documents stored for delayed send will be retained for approximately 60 minutes after the power cord has been disconnected.
