WARNING
Always disconnect the AC power cord from the power source before
doing any maintenance procedure. Failure to remove power could result
in injury to you or damage to equipment. If you must apply power
during maintenance, you will be instructed to so in the maintenance
procedure.
Three kinds of messages appear on the LCD:
♦ Status messages
♦ Operator correctable fault messages
♦ Fault messages that require your attention: the LCD usually indicates
these by adding an asterisk (*) to the message.
If a fault condition occurs, three things happen:
♦ The status lamps on the control panel flash on and off.
♦ The audible alarm sounds if it was enabled. (Press CLEAR to silence the
alarm.)
♦ The control panel LCD displays a fault message.
Clearing LCD Messages
Refer to Table 3–1 and follow the instructions. After correcting an error,
always press the CLEAR key to clear the message and place the printer in
the offline state. (If an error is not cleared, the printer will try to print again
but will display another error message until the error is cleared.)
