Check procedures/corrective measures<br />
C3200<br />
(A3200*)<br />
Exposure lamp problem<br />
• In indicator check before starting<br />
copying, the average value in scanning<br />
of the shading plate with the<br />
CCD is 128 or more.<br />
Defective scanner<br />
board (KP-5063).<br />
Defective exposure<br />
lamp or inverter<br />
board.<br />
Replace the scanner board (KP-5063) and<br />
check for correct operation.<br />
Replace the exposure lamp or inverter<br />
board.<br />
Incorrect shading<br />
position.<br />
Adjust the position of the contact glass<br />
(shading plate). If the problem still occurs,<br />
replace the scanner home position sensor.<br />
Poor contact of<br />
the connector terminals.<br />
Check the connection of connector YC-6<br />
on the scanner board (KP-5063), and the<br />
continuity across the connector terminals.<br />
Repair or replace if necessary.<br />
C3300<br />
(A3300*)<br />
Optical system (AGC) problem<br />
• After AGC, correct input is not obtained<br />
at CCD.<br />
Insufficient exposure<br />
lamp luminosity.<br />
Replace the exposure lamp or inverter<br />
board.<br />
Defective scanner<br />
board (KP-5063).<br />
Replace the scanner board (KP-5063) and<br />
check for correct operation.<br />
Incorrect shading<br />
position.<br />
Adjust the position of the contact glass<br />
(shading plate). If the problem still occurs,<br />
replace the scanner home position sensor.<br />
C4000<br />
(A4000*)<br />
Polygon motor synchronization<br />
problem<br />
• The polygon motor does not reach<br />
the stable speed within 15 s of the<br />
START signal turning on.<br />
Poor contact in<br />
the polygon motor<br />
connector terminals.<br />
Defective polygon<br />
motor.<br />
Reinsert the connector. Also check for continuity<br />
within the connector cable. If none,<br />
remedy or replace the cable.<br />
Replace the LSU.<br />
Defective engine<br />
board (KP-5061).<br />
Replace the engine board (KP-5061) and<br />
check for correct operation.<br />
C4010<br />
(A4010*)<br />
Polygon motor steady-state problem<br />
• The polygon motor rotation is not<br />
stable for 5 s after the polygon motor<br />
rotation has been stabilized.<br />
Poor contact in<br />
the polygon motor<br />
connector terminals.<br />
Reinsert the connector. Also check for continuity<br />
within the connector cable. If none,<br />
remedy or replace the cable.<br />
Defective polygon<br />
motor.<br />
Replace the LSU.<br />
Defective engine<br />
board (KP-5061).<br />
Replace the engine board (KP-5061) and<br />
check for correct operation.<br />
C4200<br />
(A4200*)<br />
BD steady-state problem<br />
• The MIC detects a BD error for 600<br />
ms after the polygon motor rotation<br />
has been stabilized.<br />
Defective laser<br />
diode.<br />
Defective polygon<br />
motor.<br />
Replace the LSU.<br />
Replace the LSU.<br />
Defective main<br />
board (KP-5060).<br />
Replace the main board (KP-5060) and<br />
check for correct operation.<br />
