Aficio 1060 (B064) curl & jam on full bleed copy

Yes, I use all Ricoh OEM parts 100% and supplies and consumables. Thanks for your input!!! I am going to take one of these "problem" originals to another Ricoh Aficio 1060 and see if it jams in it also. THANKS for all of you input!!!

One more thing! Does the solid cover the whole page? If not try feeding the original blank edge first through the ADF and / or alter the original orientation settings via the op panel.

If I am now understanding the problem, the paper has so much curl that it can hardly make it out of the fuser, and if it does, the fuser causes even more curl so that it will not even properly exit the assembly? Before the paper enters the fuser, the paper hits the entrance plate just fine and there are no jamming problems here?

Just for S & G, are all of the voltage settings for bias & transfer at factory spec?

It ALMOST sounds like the paper has so much static, moisture, or something else that is causing the curl on the paper either by the reg. area or during the tx process, although the external LCT should not add hardly anything to the curl problem. But, I believe you stated that this happens on the full bleed copies only, and regular copying is ok, correct?

What happens with even thicker paper, somewhere in the 100-130 gm/m^2 territory?

I'm not 100% certain that the problem is specific to the fuser unit itself, because you've already swapped it with another one. But, stranger things have happened. There are those decurling rollers right after the fuser as well. When you said that you swapped out the fuser, did you swap out just the fuser unit, or all of the fuser components on the rail?

Yes, trying it on another box would be a good idea, as you may be chasing something that has caused you a lot of frustration.

What happens from the bypass drawer when it is set to the thick paper setting? Are you getting the same results?

Pretty much the whole page except for a 3 mm edge.

Yes, actually, it makes it out of the fuser, so no, there are no issues with it entering the fuser.

I think I checked to see if any of the SP modes were out of spec.. but I'm not sure... I will have to add this to my list to check. I was kinda wondering if the transfer belt unit was causing an issue, so I replaced the separation grid thingy whatever its called, and made sure the belt and terminals for the belt bias were good.

Correct, only full bleed, it never curls like that on sheets full of text or something. I didn't try anything like 28# bond yet, I could I suppose.

No, I didn't swap the entire fuser, I swapped the entire exit unit minus the fuser.

I didn't try thick from the bypass because I was trying to duplicate what the customer would do, but I can I suppose.

As far as the paper type display setting, I am pretty sure that is just to inform the user and the print driver of the paper type, I'm almost positive it doesn't actually change temperature, voltage, or line speed. Once I thought so, but experience tells me different.

Thanks for all of the input, I will see what I can this week!!

Well, I got the machine to copy those troublesome originals. I'm not sure if either of my solutions will be convenient or satisfactory to the customer.

If I copy the original using THICK mode from the BYPASS, it copies OK.
OR If I copy using CREATE MARGIN (10 mm all the way around) it copies OK.

Increasing the lead edge erase to 7mm doesn't help, even though the create margin helps.
The SP 5-990-002 says all of the currents and voltages are nominal, although I didn't try metering the transfer bias roller or anything.
I still have not made it to a customer with the same machine...
It isn't over-toning with the toner supply rate.
Photo Mode doesn't help.
It does exit the fuser, and doesn't create a tri-fold anymore... now it is just an extremely wavy copy that exits the fuser, but doesn't enter the exit entrance guide.
Every once in a while a copy will actually make it through for whatever reason.

Sometimes, after one of these misfeeds, I clear the paper, and when I push the fusing unit drawer back into the machine, and I think I do it firmly enough, when the machine starts going again, there is a noise like the gears arent engaging or something, and It jams on the fuser ENTRANCE, that is it doesn't make it into the fuser. Then I pull it back out and slam it in again, and it works ok (as far as that issue).. I'm not sure if this is a separate issue or if it contributes to my other jamming issue. Perhaps there is some tweaked housings on the fusing unit or exit unit, I don't know.

Thanks..

OK, my original was tried on another 1060 and it copied fine on that machine! I think I will start with gears...

It sounds like the fuser unit is okay, and you may have some fuser drive issues instead.

I don't think I've ever come across any of the fuser stepper motor drive problems, but there are obviously drive & coupling gears on the entire slideout assembly.

The sensitivity issues you're experiencing with the fuser carriage reinstallation back into the machine does say something; yes, it could be related but also something coincidental.

One time I did have an issue with the carriage assembly not being able to come out easily. There was some tweaked frame problems on the carriage and I think the machine frame was a little bent from customers slamming the hell out of the assembly.

I would recheck all frame areas for bent alignment pins and warped catches at the front and the machine frame where it catches as well. It could only be off a tiny bit, but it could be enough to cause your problem.
