1) reate a test chart, load it in the ADF, 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
adjust the amount of skew (the range shown in the table) to within the
spec.
T-12-4
F-12-9
3) Loosen the two screws [1] securing the right hinge and slide the hinge
according to the sale markings so that the perpendicularity is within spec.
F-12-10
4) Tighten the screws you loosened in step 3.
12.4.3 Adjusting the Ellectrical System
12.4.3.1 Adjusting the Magnification
0013-1277
/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /
1) Create a test chart, load it in the ADF, 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 read-
ing speed).
Image on copy A is longer. -> Decrease the value (or increase the stream
reading speed).
3) Enter the service mode.
Sequentially press the additional functions key, 2 key, 8 key, and additional
functions 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".
9) Using the numeric keys, change the value to determine the optimum value.
Next, press the OK key. (Default: 32)
Do not change the adjustment value excessively.
12.4.3.2 Adjusting the Horizontal Registration
0013-1279
/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /
1) Load the test chart in the ADF and make a copy of it.
2) Compare the horizontal registration of the chart with that of the copy. If
required, make an adjustment.
The specified horizontal registration is 10mm +/-2mm.
No.
