Re: Light Copy

Sounds like an optical problem. Try cleaning the CIS or mirror's within the optics (not sure which it is on this machine). Failing that I would look at replacing the CIS or CCD depending on which this machine uses. Could also be Reader PCB or worst case Main Controller. More than likely just a bit of dirt somewhere within the optics part of the machine. You've already narrowed it down to that in the fact that it prints ok from a computer.

Good Luck!

Re: Light Copy

what type of area is printer in
condensation on the contact sensor of the reader unit or on the copyboard glass can cause light images

<Reader>
- Check whether the optical system (contact sensor/white panel/copyboard glass) is free from scratches, stain, foreign objects.
- Check whether the contact sensor unit moves smoothly. Check whether the rails are free from dirt.
- Check whether the contact sensor is not flickering.
- Check whether the optical system is free from dew condensation.





1) Enter the service mode.
Sequentially press the Additional Functions, # key on the operation panel.
2) Using the upper/lower arrow keys on the operation panel, select "Test".
3) Press the OK key.
4) Using the upper/lower arrow keys on the operation panel, select "Scanner

5) Press the OK key.
6) Using the upper/lower arrow keys on the operation panel, select "CS Output
Test".
7) Press the OK key.
8) Select "Yes" and then press the OK key.
After completion of the above steps, contact sensor output correction will be
performed and parameters will be set automatically.
