3. 4. 3 How to Exit Service Mode
Procedure
1. Click [Exit Service Mode] of the Service Mode Basic Frame and each screen for the
Diagnostics, Adjustment/Setup and Preventive Maintenance in the service work group.
• The PSW opens the Exit Service Mode screen (DC188). Select [Complete the
operation and exit], [Abort the operation and exit] or [Terminate the Service Mode at
PSW alone].
2. Select and execute [Complete the operation and exit].
• The PSW displays "[?] Clear the error log history in the main processor. Are you
sure?", [Yes] and [No].
a. If you select [Yes], the PSW resets the Shutdown History (DC122), Failure
Counter (DC120), Jam Counter (DC118) and No. of Copies Since Last Call,
and exits the Service Mode.
b. The display will return to the Exit Service Mode Screen if [No] is selected. In
addition, if [Cancel] is selected in the End Service Mode Screen, the previous
screen of it is displayed.
• In case the PSW cannot notify [Complete the operation and exit] to the printer, the
PSW displays "Main processor is unable to exit from the Service Mode. Check the
connection between PSW and main processor, and the power supply to main processor.
Select [Retry]. Main processor is unable to exit from the Service Mode if it is not
connected to the PSW." on the Caution screen.
3. Select and execute [Abort the operation and exit].
• The PSW displays "[?] Unable to clear the Error Log History in the main processor. Is
it OK?", [Yes] and [No].
a. If [Yes] is selected, the Shutdown History (DC122), Failure Counter (DC120)
and Jam Counter (DC118) are not reset. Then the printer exits from the Service
Mode without resetting the number of copies since the previous visit.
b. The display will return to the Exit Service Mode Screen if [No] is selected. In
addition, if [Cancel] is selected in the End Service Mode Screen, the previous
screen of it is displayed.
• In case the PSW cannot notify [Abort the operation and exit] to the Main Processor, the
PSW displays "Main processor is unable to exit from the Service Mode. Check the
connection between PSW and main processor, and the power supply to main processor.
Select [Retry]. Main processor is unable to exit from the Service Mode if it is not
connected to the PSW." on the Caution screen.
4. Select and execute [Terminate the Service Mode at PSW alone].
• The PSW displays "[?] Main processor is unable to exit from the Service Mode. Is it
OK?", [Yes] and [No].
a. If you select [Yes], the PSW can exit the Service Mode, even if it is separated
from the machine. (This is the action taken when a System Error occurs due to
the Main Processor power being turned Off, or the connector of the PSW
disconnected, thus making recovery impossible.)
b. The display will return to the Exit Service Mode Screen if [No] is selected. In
addition, if [Cancel] is selected in the End Service Mode Screen, the previous
screen of it is displayed.
Even if the PSW is separated from the machine after entering the Service Mode, neither
PSW nor Main Processor automatically exit the Service Mode. However, if you turn On/
Off the power of the Main Processor with the PSW separated from the Main Processor,
the Main Processor exits the Service Mode.
