Function
Use it to change the com-
munication speed of the
RS232C interface for ser-
vicing.
• Be sure to set it to '1' if
you have selected a
cassette exclusively for
envelopes.
The switch determines
whether the machine
should recognize an
envelope cassette.
Use it to specify whether
the density correction
curve should be modified
based on the results of
measuring the resistance
of the photosensitive
drum.

Guide
If the results of making adjustments
according to the Basic Image Adjustment
Procedure are not good, execute the 15th
screen (*4*).
If the indicated value is far off the target
value, set the item in this mode to '1' so nor-
mal images may be obtained.
However, if such a problem occurs, you
must suspect a fault in the image processor
PCB, DC controller PCB, or composite
power supply PCB.
