The references easy, moderate or complex,are an average estimate and are dependant on the training and experience level of the technician.

Adjusting the DP manually

TROUBLESHOOTING GUIDE

Phenomenon:

During colour scan (to USB, SMB, or E-Mail) via the DP,
colored vertical stripes can occur anywhere in the scan
direction (picture 1).
Also a foggy background can occur if the scanner position
is not properly adjusted until the DP is used.

Counter measure:

First try to configure the DP with the parameter U411

before you start to adjust the DP manually.

A sample of how to change the values against stripes
or background manually you can find on page 5.

(Service Manual page 1-3-36)

Note:

A4 MFP systems with an older firmware do not have all U-Paramerters to adjust the DP.
Nevertheless you can set these parameters by using several KCFG commands. Therefore see
the description on the next page.

Adjusting the DP manually

TROUBLESHOOTING GUIDE

Counter measure:

Sample:
During colour scan (to USB, SMB, or E-Mail) via the DP,

colored vertical stripes can occur anywhere in the scan
direction.

Normally it can be solved by activating the black line
correction (MFP models only) or / and changing the values
in U411, U425 and U068.

Here a sample how the value change of U068 can be done:

PAGE 5

!R! KCFG“SCAN“,9,1,20;EXIT; (change to value “20“)

Used when the image fogging occurs because the scanning position is not properly adjusted when the DP is

used. Execute KCFG “EESS”,4, 107, 1, “#1”; command to adjust the timing of DP leading edge when the

scanning position is changed.

BROKEN HINGE LID L/R
TROUBLESHOOTING GUIDE

By frequent repeated opening / closing of the top cover the hinge left / right might be broken.
From October 2010 on the material of these hinges have been changed from ABS to more stable POLYCABONATE.
In the event of such cases, please replace the hinges with the modified parts 302KV02532, HINGE LID L and 302KV02542, HINGE LID R.

We also recommend to change the RATCHET SHUTTER (302KV02501)
These measures are described in SB-2KT-0007-B380, SB-2KT-0020-D014 and are a part of the modification kit (2KT-0019-D012)
