1) reate a test chart, load it in the DADF, and make a copy of it.
2) Compare the lines at the end of the test chart with those on the copy for
perpendicularity. Measure dimensions A and B at the end of the copy and ad-
just the amount of skew (the range shown in the table) to within the spec.

1) Create a test chart, load it in the DADF, and make a copy of it. This copy
is called copy A.
2) Compare the longitudinal image length on the test chart with that on copy
A. If required, make an adjustment in the service mode.
(A4-size paper: 277 +/-1mm LTR paper: 59 +/-1mm)
Image on copy A is shorter. -> Increase the value (or reduce the stream
reading speed).
Image on copy A is longer. -> Decrease the value (or increase the stream
reading speed).
3) Enter the service mode.
Sequentially press the User Mode key, 2 key, 8 key, and User Mode key on
the operation panel of the host machine.
4) Using the arrow keys on the operation panel, display "#SCAN".
5) Press the OK key.
6) Using the arrow keys on the operation panel, display "#SCAN
NUMERIC".
7) Press the OK key.
8) Using the arrow keys, select "48".
