[Jamming] MPc4500 fuser jams

[Llama God]

Hello!

Has anybody had issues with jams in the fuser on these boxes? The paper exits the nip between the belt and the pressure roller and then goes underneath the brass-coloured guide, showing a jam at the fuser exit sensor.

I have experimented with removing the guide, however the paper then wraps around the belt.

Any thoughts?

What sort of coverage ? is it every copy ? and when was fuser last rebuilt ?

[Llama God]

It isn't every copy, but if I ask it for 5 then it'll almost certainly jam at least once. The fuser has done roughly 80k since it was rebuilt and it doesn't seem to matter how much coverage there is. I printed out a colour test pattern from printer SP and it jammed doing both mono and colour copies of that. It also jams on standard office documents. I did suspect at one point that it was to do with heavy coverage towards the leading edge of the copies, however that theory died on its arse after a short period of testing.

Incidentally, Tonermunkeh has suggested an oil roller which I am trying tomorrow morning.

[Comatose]

OK, only other thing I was going to say was that it might be worth checking the non default data and see if someone has changed fuser temperature settings

[Llama God]

Ah, I didn't check that, but I will. Thanks!

shout back if the oil roller sorts it or you find a different fix knowledge is everything !!

I had one two weeks ago that had 7 of 8 jams in the fuser. That plate you mentioned was cvered in hard toner and the oil roller was as dry as a nun's crotch. After i cleaned it up and replaced the roller she worked fine and suffice to say I haven't been back either. Also my friend may I suggest firware is up to date.

Had same a couple of weeks ago, 7 of 8 jams in the fuser. That plate you mentioned was cvered in hard toner and the oil roller was as dry as a nun's crutch. Cleaned and replaced and haven't been back since. Also I did the firmware so bear that in mind.Ignore this for some stupid reason I posted twice. Fuckin whiskey!

[Llama God]

I've cleaned the plate already so it's looking like firmware, an oil roller and checking the fuser temperatures thus far.

You've led me astray now, it's time for a drop of Ancnoc!

[Llama God]

Ok, I checked all of the temperature settings and they were all at default. I then changed the oil roller and ran a few through without jams, however due to time constraints I didn't have time to do the firmware. Up until now, almost an entire day, the customer has not been back on screaming and I take their silence as a good thing!

Thanks chaps!

I had one of these giving me Jam 019 every other copy and found the paper was stopping at the entrance to the nip. I thought there was a problem with the fuser drive , but couldn't find anything wrong with the drive. After 3 hrs of messing about with it, out of desperation I moved the fuser entrance guide to open the mouth a little wider and Presto!! Sorted.....
