ricoh finisher 730

[periskon]

iam a tech and i have some problems lately with the 730 finisher on a aficio 650 machine. it works fine when it is used with A4 paper, but there is always a jam when it is used with A3 paper. the paper stops in front of the punch unit. i have changed all the sensors on the finisher, the stepp motors,the presures on the gear belts and finally the main board of the finisher. the finisher used to work fine with all paper sizes and its not the first i have seen with the same problem. any help would be great . thanx

Stepper Motor

I have had the same problem on a number of occasions and it was always the stepper motor. If you pull the finisher away from the machine and sit facing the entrance guide. Its the motor that sits on the inside of the frame to the lower right hand side. Same fault only jams A3. If you definately have replaced that motor then try running the job with the sorter disconnected and make sure you can eliminate the m/c. Could also be related to the punch unit. Hope this helps!.
