CHAPTER 5 TROUBLESHOOTING
5. Simulation Mode A. Main Menu
1. Regist Adjustment
This mode is used to train service
technicians about service mode without
connecting to the scanner.
This mode performs adjustments on a
reading-start position and reading-end
position for feed direction automatically.
Operation Procedure If the leading- and trailing-edge positions
of a scanned image are improper, perform
this adjustment.
1) Enter the 8 characters “training” as the
password.
2) The screen is the same as in the real
procedure, and can be operated in the
same way except for some buttons that
are grayed out.
Also run this mode after replacing or
reassembling the reading unit or the
registration detection related part, or after
replacing the control PCB recording the
adjustment data. Note: Note that you cannot execute
operations that require communication
with the scanner.
Adjustment sheet
A sheet of ordinary white copier paper is
required to execute this mode. The size
is fixed at A4 or LTR. Since this can be
obtained easily, it is not designated as a
service tool.
Do not use paper where the outer shape
is slanted, or that easily becomes
jammed or feeds crookedly.
You can also use the shading sheet:
TKM-0326/0332.
Note: Do not use an adjustment sheet where
the edges have been made black
using another DR scanner. The
adjustment will not work properly.
Operation Procedure
1) Clean feed path, roller, and reading
glass.
2) Place a piece of the registration
adjustment sheet. Make sure to set the
document guides to fit the sheet to
prevent skews.
