SHARP AR-287/337/407/507 scanner drive PCB problem
Hi, everybody! I need some help for AR-287/337/407/407 etc., please!
Here I have 6-7 deffective scanner drive PCB's for all of the cougar series mashines (new type-3 phase mottor). I know that the problem with scanner moovig is on PCB (i have tried all you can imagine with the copier) , but witch exactly the deffective element is. I tryed with the 2 electrolite capaciors - nothing changes. Also replace R7-0.15 ohm - there is some effect, but sometimes burns the fuse on DC controller and the effect is temporary-2-3 months.
Please, if somebody knows how to repair the scanner drive PCB to give some advice. Is there any possibility IC2 - SLA5017 to be deffective.
Will be verry thankfull if someone help!
