Ricoh mp5500 jamming at B2

[Guest]

I have been out to a mp5500 with 1.4mill on it that jams at the guide B2 just b4 the reg roller.I have stripped the whole section out cleaned all rollers and sensors and all feed rollers the fault happends about 1 in 5 copies and from all trays.The paper then forces down the guide actvated by the gate solonoid.I have run this machine with single copies and the fault is always at this point.

Any ideas this must have had been seen B4

Change tandom feed station with the second drawer station an see what happens 20 min and its done. Just for trouble shooting.

These models use motors instead of clutches for all paper feed sections. If all trays are jamming like you said, it's got to be the main paper feed unit (registration unit). You're probably looking at bad one way bearings, or possibly even developer material contamination of the paper feed unit if the developer unit is leaking at the rear.

Worn registration mylars also cause this fault. Replace those when you're in the reg unit too.

Previous posters have this covered

to confirm

Pull the Dev Unit. Check for any signs of dev leak. If found pull the 1st feed station and check for tight motor (Front end leak) and evidence of dev around the gears at the rear end of the unit, change as required.

Also, remove and check the reg unit, the bearings, motor can be contaminated.

As mentioned, the reg mylars can cause this fault, especially if the machine has an LCT fitted.

Have had dev seals on an MP6000 go at 600K!!!!.... complete feed station (x3) / reg unit rebuild required!

How about what jam code is it giving ?

[Herrmann]

did you clean the sensor prior to the registration rollers? its hide under a metal part that tends to amass a lot of paper dust, causing the sensor going blind. give it a try

Jamming at b2

Just to let you all know that on stripping the whole feed and reg section down found major dev spill all in feed head 1 in all the bearings and gears.Have ordered new feed heads and dev unit as dev is coming out the back of the unit.

Thanks to all who posted help..........

I'll bet you,ve dev on your gears or that reg sensor is filthy(especially if it has never been cleaned). It's under the dev unit. Slide out the dev, 2 screws 1 front 1 back (you'll need a stubbie) and lift the plat over to the left and you'll se a photo sensor covered in paper dust.
