Service Call Messages
If a malfunction occurs and the machine cannot operate normally, a screen like the 
one shown below is displayed. Follow the instructions that appear on the touch panel 
display.
If a message like the one shown below appears, follow the procedure described 
below.
Do not connect or disconnect the power cord with wet hands, as this may result in electrical shock.
Always grasp the power plug portion when disconnecting the power cord. Pulling on the power cord may 
expose or snap the core wire, or otherwise damage the power cord. If the power cord is damaged, this could 
cause an electricity leak and result in a fire or electrical shock.
Sending or receiving documents cannot be done when the main power switch is off.
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.
