Self-Diagnostic Modes - Sharp AR-650 Service Handbook

1.2 Self-Diagnostic Modes

This copier is a multi-function copier (net work printer, DSS). So, compared with conventional copiers:
1) It has more setting items in the self-diagnostic mode.
2) Setting items are related to each other.
For this reason, if normal operations are continued on the control panel (by [0] + [9] or [C] keys) when
adjustments are completed, operation trouble (e.g. machine lock) may occur due to the internal structure
of the program.
So, when the self-diagnostic mode in adjustments after unpacking, servicing or preventative mainte-
nance, first turn the power OFF before handing the copier over to the user.
