Adjustment Of Ae Sensor Level - Sharp SF-2030 Service Manual

(3) Adjustment of AE sensor level

1 Perform Simulation 47. (The mirror base makes scanning motion
and stops at AE sensor level measuring position).
2 Place four or five A3-size (or 11" x 17") papers one upon another
on the original table.
3 Press the print switch again. The copy quantity indicator shows
the AE sensor output level for blank paper, which is stored in
memory.
(4) Setting of drum sensitivity
1 Perform Simulation 26-07 and check that the first digit of the
4-digit drum number printed on the front-frame sided drum flange
is shown on the copy quantity indicator.
2 If the indicated number differs from the drum number, press the
copy quantity key to change the setting.
Note: If the setting is done with the copy quantity key, the indi-
cated number is limited to 1, 2 or 3.
(5) Setting of test chart
1 Align four or five papers with at least 120 mm in width and ap-
prox.420 mm in length one upon another.
2 Set the test chart (UKOG-0162FCZZ) on exposure glass towards
machine front side as shown.

(6) Adjustment of copy density
A. Checking the developing bias output
Check that the output value is –150 V when the exposure is set to
"1" in the manual exposure mode. Perform Simulation 8-01 for
checking the developing bias.
B. Adjusting the density in manual exposure mode
1 Perform Simulation 46-01 for adjusting the copy density.
The exposure indicator of the operation panel shows "1" of the
manual copy mode.
2 Check that the cursor is on ME.1.
IF the cursor is not on ME.1, use
select ME.1.
3 Make a copy.
Check that the "6" of UKOG-0162FCZZ (or 0.5 of UGOG-
0089CSZZ) has slightly copied and "5"(0.3) is not copied.
<When light> Decrease the value shown on the copy quantity
indicator.
<When dark> Increase the value shown on the copy quantity
indicator.
