Hi all...

what jam codes are logged in the smc logging data report?

Hey I had a similar issue and it turn out to be the shift tray lift motor, the problem starts with the jams and as the motor gets worse you will get error codes. the tray doesn't go up and down and that's why it jams.

Check that

Hi "Copierguy" thanx for this info but its not that.....shif tray work fine, I swoped the finisher with another finisher and still the same. To "Callme" the jam codes is as follows: plotterjam hist = 100 P/jam location ="Finisher entrance" = 104 thats it !!
Hope that helps !!
Thanx

Okay, let's go through this. You've said you've swapped the finisher and it's still doing it. That leaves only a couple of things it could be. Firmware, duff finisher connector on the machine, harness connecting finisher connector to BICU and BICU itself.

Update ALL the firmware to latest levels, absolutely everything including the finisher and try again. After that it's board time.

Unless that is - you've two finishers with defective entrance sensors, broken junction gates or missing / disconnected springs!

jam 104 is actually

Finisher Drive Motor
(B408)
Exit guide plate HP sensor does not turn

on or off for specified time.
jam 103

Lower tray exit sensor does not
detect paper after the stack feed-out
belt has fed paper.

��

Lower tray exit sensor still detects
paper after the stack feed-out belt

has returned to the home position
jam 102

Finisher Staple (B408)
Paper does not reach to the staple tray
entrance sensor or stay at the staple tray

entrance sensor.
jam 101

Finisher Shift Tray Exit
(B408)
Paper does not reach to the lower tray
exit sensor or stay at the lower tray exit

sensor.
jam 100

Finisher Entrance
(B408)
Paper does not reach to the entrance

sensor or stay at the entrance sensor.
so if your jam is 104 then it is not finisher entrance.

i had a mad fault like this and it turned out to be the door sns in the bridge unit. It thinks the door opens and happens so fast it does not appear as a fault code or on display.
If not then i would go for IO pcb .

good luck

Cheers
