2. OPERATOR CALLS & SERVICE CALLS
2.1 Operator Calls
An ‘operator call’ which the printer indicates on the LEDs is user recoverable. Identify the error
from the table below and take the corrective action described for each indication to correct it.
The printer automatically recovers from most errors, but it may also be necessary to reset the
printer with the control panel button.
LED Indication Error Remedy
Alarm LED is blinking. Cover open Close the front cover. If the error is not
cleared even after closing it, open the cover
once and close it again.
The error may occur because of the laser
BD malfunction. Refer to ‘M-7 BD failure’ in
Section 6.

Alarm & Data LEDs are ON. Toner empty Replace the toner cartridge with a new one.
2.2 Service Calls
When the printer indicates the need for a service call by illuminating all the LEDs and then a
combination of LEDs alternately as shown in the table on the next page, a user unrecoverable
error may have occurred.
Instruct the user to turn off the power switch, wait a few seconds and then turn it on again and
try to print again. If the error is not cleared and the same service call appears, see Section 6
‘Malfunctions’ to take the corrective action.
