Scanner Service Error
Problem
LED Indication
Cause
Sub ASIC Error
‘E’ and ‘0’ are
displayed
alternately.
Hardware error of the scanned data.
When the pixel number per line is over the
specified value, the error occurs.
It will be caused by Sub ASIC and D-RAM
malfunction.
Hi-Ref Adjustment Error
‘E’ and ‘1’ are
displayed
alternately.
Error of hi-reference adjustment which is
performed with using the document pressure bar
when the direct copying or PC scanning is
started.
The error occurs in the following cases;
If the output from the CIS is less than 1V.
If the output from the CIS is low because the
document pressure bar or the surface of the
CIS is dirty.
If the hi-reference value cannot be changed
due to the LC82103 malfunction.
If the CIS is connected correctly.
Light Level Adjustment
Error
‘E’ and ‘2’ are
displayed
alternately.
Error of light level adjustment which is performed
with the document pressure bar and the
document end.
The error occurs in the following cases;
If the output from the CIS is too high even
though the parameter is changed till the LED
is OFF.
If the LED light level is still high due to the
Sub ASIC or PWM malfunction even though
the parameter is changed.
If the output is high due to the CIS
malfunction.
If light level cannot be adjusted correctly due
to the LC82103 malfunction.
White Distortion
Adjustment Data Error
‘E’ and ‘2’ are
displayed
alternately.
Error when creating the white distortion
adjustment data, which is performed with using
the document pressure bar when the direct
copying or PC scanning is started.
The error occurs in the following cases;
If there is the white level data whose value is
smaller than the one of the black.
If some parts of the image sensor in the CIS
are not normal.
If the document pressure bar or the surface
of the CIS is dirty.
If D-RAM in the LC82103 is not normal.
<Remedy>
When the service error occurs, press the Stop key on the scanner control panel to clear the error.
If the service error often occurs, you need to repair or replace the main PCB and the scanner
related parts such as CIS.
