MPC 3000 various jams

[aabarnes1]

Evening gents, I,m having an issue with jamming in various locations. The first is the paper exit, then fuser exit and registration then the odd finisher jam. Machine has just short of 500k on it, a new fuser and p/f tyres. All the exit rollers and sensors are clean. Now sods law decrees that when a tech is on site no jams occur, however the smc tells the truth. Has anybody had similar??

Does it do it simplex or duplex? Or does it matter?

What are the jam codes? Any "Power On" jams?

Both, it doesnt' matter.

No power on jams- I fixed that ayear ago, the codes are 19, 20 and 17 aswell as 133.

Is there pattern to when the jams occur? etc. Monday mornings? There could be a certain someone with a certain job that causes the problem.

I'd agree with this. The jams are too random to be able to pin a cause down, especially as they are all over the machine. Crap paper perhaps?

Also check for weather it is A4 LEF or SEF etc. 05h = A4 LEF

Or check SP-7-506 (jam count by paper size) if it jams on a size only loaded in 1 tray. Do a long run on this tray. Also make the customer run the M/C to see if it is something there doing.

Try to find something common.

I,m posting back on this just to let you know the story. I was back in there today with jam code 20 and 26 practically constantly. In another room there is another mpc so i stripped off the bridge unit, exit guide and front cover.in order to observe the machine's operation in both duplex and simplex.To my shock, horror and fuckin amazement I noticed the white actuator arm that is attached to the solenoid and operates the invertor gate was not 'threaded' into the solenoid pin but resting on top of it therefore restricting movement of the inverter gate.I put the fucker back in it's rightful place and ran 500 duplex lef A4, 100 sef duplex A4, 50 A3 and 20 thick card thru bypass- all sucessfully.
This was extremely difficult to spot as the arm appeaed to be seated correctly, lucky I had the other machine close by. I asked the 2 other lads who'd been there before me- naturally both denied any knowledge of fixing this area. The reason I asked them is because it is practically impossible to dislodge the arm without breaking it- you have to remove the solenoid to fit or remove the arm! Thank fuck that bastard's over with.

UPDATES ARE GOOD!!!

Isn't that a bitch. Another tech doing something and not wanting to admit it. Not surprising. Glad you figured it out. I'll keep this in mind.
