3. SERVICE CALL CONDITIONS
3.1 SUMMARY
When a service call condition occurs, SC codes are displayed in the copy
counter. The first three digits are displayed in the copy counter. Hold down the "
•
"
key to display the last two digits.
Example:
When the copier detects the E507 condition, "E-5" is displayed in the copy
counter. Hold down the "
•
" key, and "07" is displayed in the copy counter.
There are 4 levels of service call conditions.
Level Definition
A The system goes down. The SC can only be reset by a service
representative using SP5-810 (see the note below), to prevent the machine
from being damaged. The copier cannot be operated at all.
B The system goes down. The SC can be reset by turning the main switch off
and on if the SC is caused by a detection error.
C The copier can be operated as usual except for the unit or feature related to
the service call.
D
Only the SC counter is incremented. The copier can be operated as usual.
NOTE: For safety reasons, Level A service calls cannot be cleared by turning
the main switch off/on. The following procedure must be performed to
clear these service call conditions after servicing the machine.
1. Turn on the main switch.
2. Enter SP5-810 (SC code reset) and press the Enter key.
3. Exit SP mode and turn the main switch off and on.
