MP 5000 Fusing Web

[rthonpm]

All,

I've been fighting this for two days now. I'm trying to replace the web on a 5000 and I can't figure out how to get one of the gears on the take up roller off. The part number is AB010177, but there's a screw or spring or something (Hexagonal set screw) in the gear that locks it to the web shaft. I cannot figure out how to get that spring/screw/pain in the ass out. I tried an allen wrench to no effect and Ricoh tech services was no help. Anyone out there had any success or do I need to eat the cost of a new web assembly?

They call us technician.So used your technic to fixed that one.Just try to visually check how to replaced that one.HeHEHe!

Is this the bit you mean?

That's the little bugger. Right behind what's listed as C in that illustration.

[cobiray]

By the look of the illustration there is a allen head set screw in the non tooth section of the gear.

I guess if that allen screw broke or was stuck that would be a bugger to change.
The only issues I can think of would be if you were not using metric allen key then you would mangle the screw.

Cannon copier seem to have very good and clean system however the
# of parts involved in the assy seem to be the worst among other brands.

Using the right tools eg the metric size allen key is important when taking
out parts.

I tried the Allen wrench last week (metric sized) and all turning it in that set screw does is bend the wrench. I took the whole web assembly back to the shop and the rest of my team tried different tactics as well to no effect. We endedup using the web from a demo machine to get the customer back up, but now we still have a web we can't replace on our demo machine.
It doesn't help that the service manual refers to this set screw as a 'spring'. I guess the regular translator was off that day...
Just another of Ricoh's overthinking on this machine. A cleaning roller worked quite nicely on the previous versions of this machine. The fuser was never the issue on the 35/45 family: it was the drum and developer system which oddly enough is still an issue on this model as well!

I've broken a couple of small allen keys trying to undo this type of screw when they have been over tightened.

1. You could try some WD40 to see if that helps break the screw loose.
2. Or you could try heating up the gear collar so it expands just enough to get the screw out.

The parts manual calls it an M3 Hex Set Screw.
It wouldn't be the first set screw I had to drill out. Use a slightly smaller drill bit then an easy-out to remove the screw.

MP5000 Web problems

This is a common problem on all of the MP5000/4000 machines
i have replaced the web assembly and sent the old one back to ricoh
the only other thing i have done is to order the gear and a packet of
the grub screws and i just drill the buggers out and replace the gear and
screw but dont tighten it up too much so i can remove it with no issues
when the web runs out next time.

I changed my first a few days ago. I got it out with a standard size allen wrench. I thought I had stripped it with a metric and was trying anything I had. Who ever designed this should try suicide.
