They are getting a warning on the light bulb\r\nSense Key=0x4 ASC=0x680 DDES=0x7E

Hi Dana,

The error you are receiving is Flatbed Optical Alarm.This alarm occurs when the READ command for the first document is received, or when gain of the CCD amplifier is adjusted (sheet guide is read) during scanning.Probable causes are:
- The lamp, optical system or white sheet guide is dirty
- Defective lamp, heater, CCD, or inverter
- Connector disconnected
  1. Does the same symptom occur after turning OFF and ON the scanner? Check the scanner.
  2. Is the White sheet guide (glass) in the FB cover dirty? Remove the FB cover and clean the White sheet guide (glass).
  3. Is the Optical unit dirty?Are cables damaged?Are the connectors connected properly?Check all.
  4. Do the Lamps FB light up?Are cables damaged? Are the connectors connected properly? Check if the lamps light up during the Paper feeding test.If not, the error is caused by the defective Lamp FB or Inverter.
Hope the above information is helpful.

Thanks & regards,

Kyocera c3200 error Problem

A C3200 is as follows:

Exposure Lamp Problem.

• In indicator check before starting copying, the average value in scanning of the shading plate with the CCD is 128 or more.


Defective scanner board (KP-5063).
Replace the scanner board (KP-5063) and check for correct operation

Defective exposure lamp or inverter board.
Replace the exposure lamp or inverter board.

Incorrect shading position.
Adjust the position of the contact glass (shading plate). If the problem still occurs, replace the scanner home position sensor.

Poor contact of the connector terminals.
Check the connection of connector YC7 on the scanner board (KP-5063), and the continuity across the connector terminals. Repair or replace if necessary.

These are direct from the Tech man.
More than likely it is the Exposure Lamp.

Hope this helps.

Check that the lamp is not burning out, or replace with new lamp. Check the glass area to make sure there isn't a thin plastic sheet on the glass. This should be removed. Let lamp warm up for about 5 minutes before using.
If your problem still persists, it's not your computer, but likely the scanner software inside the scanner itself.

Adjusting the lamp

Hi,  This is normal for the 4200F and it's just the time taken to warm the scanning lamp up. Once it's warmed up it shouldn't need to go through the process again for any additional scans, unless it's had long enough to cool down again of course.
I've noticed from another answer to an earlier question that if it's a big problem you can change the following keys in your registry:

 Energy save changed to 1
 Lamp Off Time changed to 0

Looks like this would prevent your lamp switching off at all unless you unplugged your scanner which would undoubtedtly shorten your bulb life. It may be a better idea to play about with the 'lamp off' key number until it just stays on long enough to not cause you problem.

Cheers, Derek
