When a service call error occurs, the error is not cleared and the error display remains on the operation panel even if printer power goes off and on.
This is to avoid thet the user can cleare service call errors preventing the printer from damage.
Service call errors can be cleared, however, by starting up the printer with the service mode.
Codes in parentheses are not displayed when a service call error occurs.
These codes can be checked in the error history by using SERVICE MODE> DISPLAY> ERROR.
