3. ADJUSTMENT
3.1 CS LED Lights-on Duration Adjustment
a) Overview
This adjustment is used to eliminate uneven scanning which can result from variations in light
intensity between individual LED’s. Performing the adjustment will therefore have an effect
on scanned and copied images.
The adjustment value is registered in an SRAM IC which has lithium battery back-up and
will not be lost even if power is turned off. However, the SRAM data can become damaged,
for example by battery depletion. In this case, the machine checks the data’s validity the next
time power is turned ON. If the data is invalid, the adjustment is made automatically.
Because the user is automatically prompted, it is almost never necessary to perform this
adjustment during normal use. However, if the SPCNT board, Contact sensory ass’y, or
lithium battery is replaced, be sure to perform this adjustment. Also, if the color or brightness
of scanned or copied images is faulty, performing this adjustment may correct the problem.
b) Procedure
(1) Check that the ADF or pressure plate is closed correctly, then perform the adjustment by
following the steps described below.
Figure 4-2 CS LED Lights-on Duration Adjustment Operation
(2) The adjustment procedure is finished when the display reads TEST MODE. To leave
the test mode, press the Stop/Reset key, and then ON/OFF key.
