IR7200 ADF Copying

[jiongpao]

Hi, Im working on this problem for almost whole day but i still cannot fix it that if we using the platen glass for copying its working fine, but after that when we use ADF it show at the screen there "remove the original from platen glass". Theres nothing on platen glass. Once we insert the original on ADF it will always show that massage on LCD Screen. I've done cleaning the IC, TLP1241, PHOTO-INTERRUPTER (See picture) ir7200 ADF.pdf , changed ADF Controller PCB, cleaned the platen glass, cleaned scanner mirror & lamp and reload the firmware using SST but the problem still the same.

Please Will appreciate if someone give me some clue on it?

If you power on and use the adf before using the copyboard glass, will it work? If so you may have to change ps103

Yes it work on ADF before using copyboard glass when the machine turn on. When lifting the ADF for first time then it wont work again until we need to turn off the machine and on it again. Will try on changing the ps103
