mp6001 jam

[Mark Bbb]

Hoi,
Jams more often from the moment it has made more than appr.900 prints.
Jams in the exit of the fusing area - or - in the entrance area of the duplex.
There is a earlier bulletin, here on this site, which said that sensors sometimes need to be replaced.
Or there is a spring at a white gear (?) which is deformed or so...
These machine has counter 2.700K, could replacing those sensors be a solution here?
Also the left tray of the tandem tray sometimes don't detect paper, it is probably the same: sensor?
Thank you for your good help!
Greetings,
Mark

Can't help much on the paper jam issue not fully understanding your problem on that, but with the right side of tandem not detecting paper I've noticed that if you stack your papers on the left side and let the machine move them to the right it never gives the out of paper sign when it still has paper its worth a try. Maybe if you could give a more clearer explanation on the jam issue someone out there will be able to help...

All the best

Re: mp6001 jam

OK, more info:
I have been there this morning, and removed the rear covers of the machine and the finisher.
After this removal all the finisher jams were gone! (It would jam in the exit in the feed out movement, and the bundle is than blocked in the exit and is twisted.)

Jam enteance duplex: probably the driven roller holders metal plate; might be bended.
The funny thing is it all works fine without the covers (I have replaced all the filters some time ago)!!!

But still there is a problem with the right tray of the tandem: "no paper", i'm going to change the sensor.

So, thank you for your answers and comment

Re: mp6001 jam

Have you checked that the paper in the tray is stacked evenly. If either of the fences that swing out to allow the paper to be pushed in from the left side is being held open by uneven stacked paper, the paper will not lift and will show the right tray as empty.

Re: mp6001 jam

Slimslob: yes, i have checked that. The paper is aligned properly.
When this problem occures, customar switch of machine and switch it back on, only to reset this failure!
I noticed that you can reset this failure also by removing the paper of the right tray, close that tray (paper bottom plate will rise and go back down because off no paper); and then load the paper again...
So, could it be that sensors are just bad?
And then linked to the jams i have with duplex, could it be the same: bad sensors?
At the other hand, i thought a sensor works fine OR NOT AT ALL (at least when it is clean, in position AND not dirty)...
What is your experience about bad sensors?
Thank you for your answer!

Re: mp6001 jam

You should be able to go to sp5803 to check sensor input to see if they are registering on/off. On the tandem tray make sure you dont have a small chunk of paper behind the tray blocking the connector, also try unplugging the sensor and reseating the harness at both the machine side and sensor plugs, sometimes the connections get gummy and cause intermittent issues. Also some of those models have a sensor on the left wall of the machine if you take out the carriage holding the fuser and exit sections, that sensor gets dirty. There is also a spring clutch on the exit assembly that may need replaced.

Re: mp6001 jam

Dear Counsel, i thank you for this good info.
I will checked it out asap; the machine is located in a school and examinations now are being printed... i think i'll go there next week.
In every case, without the rear covers machine works fine!!!

Most sensors are nothing more than a LED and a photo transistor. Normally they work. Sometimes they fail hard. Sometimes they fail soft i.e. they work when they feel like it. Often it is just a connection problem. Some times it is an alignment problem with the actuator flag. Tandem trays are notorious for flag alignment errors, specially the gait position sensors.
