Hello
I know very well Ricoh Aficio 2090\2105,but i really i do not what to do this time.
SC 723 means a problem of HP sensor,motor or finisher mainboard of shift positioning mecanisms.
I have uploaded a photo to make more clear my problem.

Shift positioning rollers in finisher paper exit,must move forward and backward to collate paper in finisher tray,but i saw that wasnt happening and give some missfeeds in finisher paper tray exit.I took out the mechanisms and changed motor,which was blocked because it makes some cracks when i rotate by hand.Also i changed sensor of the motor mechanism and put it back again in finisher.The motor also doesnt rotate and i also changed the motor and sensor again but still the same.The mechanism is oiled and move easy when i rotate the motor by hand .
I tried to rotate the motor in SP mode,but the motor just is locked,but doesnt rotate.After 2-10 minutes with copier swiched on,copier gives a SC626,which means bad comunication between copier and finisher,if i remove the wire of motor,sc 626 dissapear.When i press collate in touchscreen,copier give SC732.I changed the wires of motors and sensors,but nothing new.I dont know what to do,except updating firmware.
Any suggestion please
