Sharp MX753 with mx-fn15 finsher jamming at inlet port

[leo34staffs]

Hi all,

I hoping theres someone out there who can help!!

I have an fn-fx15 finisher thats jamming at inlet port ( the jam log shows remaining jam). It seems as though the paper coming from the machine is hitting the paper thats in the buffer roller and causing this jam, i have ordered some sensors and some flags as they tend to get nicks in them.

This happens intermittently and i am normally out the door before they call me back!!


Any ideas would be appreciated.

What exactly is the jam code?

What exactly is the jam code?

The jam logs always show FPED_S.. some paper is in the buffer unit when the jam happens and it looks like the next sheet from the machine is hitting the paper in the buffer. So far I have changed the inlet sensor and flag. . Also the sensor and flag at the top of the buffer. ( there is a sesor in the bottom of the buffer that has not been changed but when tested it worked in sensor check.

perhaps a problem with the switchback assy?...just a thought...

In the end I used the buffer unit (complete) off the customers older mc (fn14) and had no issues. Luckily they don't use the finisher for stapling on the other mc.
