mp 4054 curling on the ends

Re: mp 4054 curling on the ends

in this picture the bottom is where the paper would enter the internal finisher[ATTACH=CONFIG]51204[/ATTACH] i see no difference hence the paper would still curl upon exiting the fuser as in the photos on the first page

When entering the 1 bin tray or the duplex reversing tray, the paper comes out near the top. The arm hanging down is the tray full detect for the 1 bin tray. The 4 small rollers are where the paper exits to enter the internal finisher, the bridge unit or the standard exit tray.

yes , this is where its getting jammed due to the curling, so i was wondering if there was a guide missing or something needed to be changed as in the color machine when u add or subtract a finisher..

Re: mp 4054 curling on the ends

Im sorry slimslob, I have an issue with it entering the finisher,, i dont need an extra exit choice,such as the internal bin, or am i miss understanding your intention here?, sorry for the confusion on my part.

No, I thought that your were referring to the side tray available on some models.

Re: mp 4054 curling on the ends

see photos...
I have this machine doind this curling on the edges, therefore causing jamming into the internal finsher..Is there a different exit paper guide roller assmbly like on the color machine(different interchangable piece in the paper exit path just outside the fuser)I dont think there is, and i cant see where there would be one, but as it stands the pics say it all. The machine has 28k on it, but I think the fusing press roller is faulty. please advise, is there a pressure adjustment on this? none im am aware of,,, or is it just bad press roller.

Silly question but have You tried another paper?

Re: mp 4054 curling on the ends

yes, even though the client is using cheap paper, i sent some paper i had that was good quality, through it, same thing, it looks like the pressure roller is either putting too much pressure in the middle or the ends are not pressing with enough pressure , im not real sure, and i dont have another fuser to swap with, the fuser is not "worn" by any means, it still looks new, Ive seen moisture in paper curl the whole page, not just the ends...wierd.

Make them print A4-R or American equivalent LTR-R(maybe) until you find another fuser to test.

Then I would pull out internal finisher temporarily if it is bad again fuser is culprit.

According to the MP 4054 service manual, NO.

Depends where the moisture is in the paper. If the corners are damper they will curl more. But in looks more like the paper is catching on something like a burr on the duplex gate.

Personally I have yet to see an internal finisher that was worth a crap after about a year of heavy use.

Re: mp 4054 curling on the ends

I had to remove this finisher from an MPxxn4 b/w because of the same issue. The machine was placed near the entrance door so there was a moisture built up in the paper stacks leading to these "seasonal" issues. It's getting even worse if there's a punch kit installed.

If you can't do anything about the enviroment/paper quality the options are removing the internal finishing options or upgrade to a tall finisher (wich also can have some trouble if there's a lot of curling but they are more tolerant)

Re: mp 4054 curling on the ends

yeah this makes sense, the client lives on the beach, there machine is one door away from outside and there dock. im trying heavier paper

Re: mp 4054 curling on the ends

I always recommend at least 24# paper (do the calculations for all you metric folks) for any colour machine. It's a little heavier and holds up much better especially with any degree of coverage on the page.
