[Jamming] mp 5000 driving me crazy

[Guest]

A very good morning all.Gentlemen i have this Gestetner mp 5000 that is giving me a nightmare. It"s showing jam 001 at paper feed and fuser exit sections although ther is no paper jammed. We changed the bicu,psu,pwer pack,inetrlock swithes,sensors and motors etc but still no joy. Kindly come to our rescue A.S.A.P

Re: mp 5000 driving me crazy

have you checked the paper path and the sensor feelers.Maybe there is a small piece of paper seen by a sensor. wow you have changed a lot of parts for these only.

Re: mp 5000 driving me crazy

I didn't see it mention but did you replace the feed/pick/sep rollers in the feed section, and jam with no paper int he machine is prety common when the tires are bald and just spin on the paper without grabbing it. Then I would clean the paper path sensors. I hoping you tried that but forgot to mention it, its usually step one for me. No paper feeding usually I do tires, sensors, torque limiter, and work my way from the feed unit through to the exit checking it all over for paper dust and paper chunks.

Oh I didn't think of it before but if you have a bridge unit try swapping that with a working machine, their is a TSB i think regarding the bushings on the unit, and also the two switches in the bridge unit go out and can cause a Jam code at power on. We usually replace both switches, and I believe there is a firmware update that changes the detection time on the switches. Might give that shot.

You had the exact same problem 1 day prior to this on a Gestetner MP3000 here:

Neither model exists. If you would start by stating the proper model, perhaps you'd get some helpful advice

J001 is a non feed from tray 1. If it's jamming at the fuser exit you won't get J001. It's most likely a clutch or worn feed/separation rollers.

BTW, why do you change a PSU, and a Hight Voltage Power Pack to solve a paper jam? Questions, questions......

I thought J001 was power on jam and J003 was tray 1 non feed jam. The J001's are usually caused by the bridge unit switches. there is also firmware out that are supposed to take care of J001 jams.

desmond didn'nt specify the correct model, so I'm just guessing. You may be right about the J001.

I was pretty sure the J001 codes were bridge unit firmware or switches thats why i recommended that, i think on these machines J003 is the non feed tray 1. I could be wrong but I think i have had a few of those bridge units go out.

Re: mp 5000 driving me crazy

According to Ricoh J001 is jams at power on:

[Cause]
The cover interlock switches on the bridge unit BU3000 may be dirty or oily. This can cause an intermittent "door open" condition.
This condition can be tested by tapping on the covers of the bridge unit. Check if a door open condition is displayed momentarily on the control panel.
[Action]
The switches can either be stripped and cleaned of internal contamination or replaced. The part number is AW50 0023.

This list is from an MP2550 manual, but the basics should be the same:

5 Paper is not fed from tray 3. Y
6 Paper is not fed from tray 4. Y
7 Paper is not fed from the LCT. Y
8 Paper is not fed from the By-pass tray. A
9 Paper jammed at the duplex unit. Z

They have come out with firmware to rectify this problem. They have increased the amount of time it takes to detect a door open signal for the bridge unit which so far seems to have taken care of the problem on a couple of my machines. Only time will tell.

It seems that this person may not be a "real" person at all. Perhaps a bot (or person) posting a few initial messages with information that looks legit on the surface, but is just testing the waters in preparation for a SPAM fest...

You notice that despite a request for clarification on the previous posting, "they" never responded back, but have been log in to the site here since then, as they posted this identical posting, just with another invalid machine model.
