Error Code Displayed

Diagnostic codes such as error codes, service man displayed, wrench displayed, and any other unusual symbols displayed are indications of a preset maintenance call due, machine service needed, developer change needed, blown lamp, or a serious machine malfunction.
The severity or immediacy of these codes and symbols range from nil to unplug the machine immediately. With some machines and or with some diagnostic codes displayed, the machine may or may not "Lock You Out" of operating the control panel and prevent continued operation.
To know what is actually going on you need a Service Code Sheet. Often times you may be able to temporarily re-program the copier to allow continued operation until you or a service tech can remedy the situation or problem.
