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.

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.
