iNTRMITTENT JAMS AT FUSER ENTRY, CLEANED ALL ROLLERS AND PF ROLLER/REG ROLLER.ONLY HAPPENS EVERY 5 OR 8 COPIES, NEVER HAPPENS ON ASINGLE A4 COPY FROM TRAY 1. aNY IDEAS????

[schooltech]

I'm not an expert on these machines, but if it never happens at the fuser from single-sided A4 from drawer 1, then you can probably isolate the fuser as not being the problem. If, say, it was a sensor arm that was sticky or something, it would show it on anything you copy.

You may have something on the vertical transport area that the other drawers use that drawer 1 does not use.

What do the recorded jam errors show as the sensor(s) having the problem?

Enter Service Mode, then look under sp7-504 and 7-507, what code is reported?

1224c Jams

Thanks for your early reply, I dont have the smc with me as I'm at home, however I do recall earlier it was registering jams at registration and fuser exit

[aabarnes1]

I'm at home now and dont have the smc. But I do remember that registration and fuser exit jams were logged

[Llama God]

If it doesn't happen from tray 1 at all, maybe it's a sticking relay clutch? Or, as Schooltech says, the vertical transport guide from tray 2. The fuser jams could be a broken interchange gate of something of that ilk if it only happens on duplex, but that wouldn't explain the registration jams.

Try resetting the jam counter, run it single-sided from each tray until it jams and eliminate from there. Alternatively just smash the insides to bits with a big hammer and instruct sales to upgrade it!

Has the rubber roller inside the fusing belt perished, you can usually see small fragments of rubber in the fuser, or when you turn the blue knob the belt has a diagonal ripple running thru.

This gives uneven pressure and causes jams at fuser entry.

Also had problems with transfer rollers, but usually the paper gets jammed on top of the image transfer belt or scrolls the paper under the fuser

[KopyKat]

I agree with schooltech and llamagod that if Tray 1 doesn't jam it's not your fuser.

That model is famous for feed, relay and reg clutches going bad. My rule of thumb is that if one clutch goes, just order all of them because getting around in the back of that monstrosity is such a royal pain in the ass. But if you want to punish yourself twice, you can swap the feed clutches from Tray 1 to Tray 2 for testing.

Also, just because you clean the feed rubber doesn't mean it's good. Replace it.

And if you go the 'hammer smash' route...post pictures!

[Passthebiscuits]

When you say "NEVER HAPPENS ON ASINGLE A4 COPY FROM TRAY 1" do you mean it doesnt jam from tray 1 when you do a singular copy but it jams on multiple copies from tray 1?

Or it never jams at all on tray 1? if this is the case which trays does it jam from?

yues thats corresct it will push 1 2 or 3 copies through but any more the it jams.

[Passthebiscuits]

I think Schooltech, Lllama God and KopyKat thought you meant tray 1 fed fine

Well I replaced the paper feed clutch and it seems to have done the trick. Thanks for the input lads

And I was so looking forward to the big hammer smash photos!

Seriously, Good Work and thanks for reporting back...it helps a lot more techs than you can imagine.

KopyKat is on the money there, the feed, forwarding and reg clutches get contaminated with silicon oil fumes from the vent pipe just below them. (great bit of design there fellas!) If one has gone the others are not far away from failing. Do your self a favour and order them in now.

Hence the Engineering Code Name is Uranus. No Joke!
