Hello everyone, I need some help with this one. Its an MP5000. It shows a J001 jam in section C and it wont clear. Cust says it didn't really jam and there are no recent jams logged on it. I checked all sensors and interlocks through the input checks in SP mode and they all checked out. Im going this morning to replace the IO board. Is there something else I should be checking? Seems like a simple problem but I haven't put my finger on it yet. Any suggestions are greatly appreciated, thank you

Re: mp5000
J001 is a jam found at power on or door closure. It usually is a scrap of paper on a sensor or a defective sensor. It also can be a bad door switch. If a door that has to be opened to clear a jam is not opened, the jam indication will not be cleared. Check the location of the last jam that was recorded in SP 5707 Plotter Jam History. -
Re: mp5000
Thanks for the response. The last jam in the machine was last month, 5000 copies ago. I checked the door interlocks and jam sensors using the input check in sp mode. I had the exit assem. out and checked for a scrap or label, none found. Yesterday I replaced the side door interlock and the IOB......no change . It doesn't have a finisher or bridge unit in it. I'm running out of ideas and could use some other suggestions. Thanks a lot for any ideas.Comment

Re: mp5000
Bad news, I had one with this same issue, nothing worked, I did everything your doing, I had to replace the machine and use it for spare partsComment

Re: mp5000
if it has a bridge unit, replace both sensors for the doors, they will flake out and cause false jams codes and not reportComment

Re: mp5000
If nothing works please check/replace EEPROM on BICU.
Part Number: 14076362 EEPROM:BR24I64-W
That is the part that holds all JAM and SC codes. If it cannot be readen/written anymore that's one of the problems you get.Comment

Re: mp5000
I believe this is one of the machines that the firmware changed the timing of the door open detection for the bridge units, I've updated all of mine and haven't replaced switches in a while.

Re: mp5000
Thanks for the responses everyone. I started taking each sensor out to inspect them and found that the tiny hole in the fuser entrance sensor was partially blocked causing a false reading. Cleaning it with lps and canned air took care of the problem. Oddly enough it wasn't blocked enough to prevent the input code in sp mode to show it was working. Thanks again.Comment
