[Error Code] C-1260 SD-506 Paper Guide will not retract to home position

[pudgi300]

Have Bishub 1200 with sd-506. Operator replaced staples then had c-1260. When it boots up the paper guide comes out but does not retract. When
disengaged none of the dipsw's in bank 7 are at 1 but the saddle stitch is grayed on the console screen. I have replaced the guide motor M25 and ps46. That did not help it.
The motor runs and the ps46 checks ok in input 71-23. Anyone have a bad sd control or sd drive board go bad for this problem. Any tips on getting the saddle stitcher back active on
the console.

Just realized i was looking at dipsw bank 7 instead of 34 will check them tomorrow and post back

OK went in today and cleared dipsw 34 0,1,3 and reboot. checked icp13 and is ok 24v. seen it work 1 time so think it is a different sensor or bad wire. Going to check sd506 right door interlock. Still will take any tips to get this thing rolling again.

Went in again today and put in my spare folder unit from an sd-501 and it works perfect with m25 motor and ps46 from old unit also swaped ps20 and ps21 from old unit. Put the sd-506 on
the bench and found it had a bent knife stopping the guide rod from going all the way out. Moved the bent blade out of the way and looks like that was it. Will replace the knife and put it back in. Hope this may help someone in the future.
