DPC 354 wrinkle

[copiman]

I have a DPC354 that wrinkles the paper intermittently. Maybe 1 in 100. I replaced the fuser unit with one that I removed in the field. This fuser was not showing any problems in the field. And I still have the problem. There is no skew either. Just wondering if anyone knows anyhting about wrinkling on this machine?

Re: DPC 354 wrinkle

I would agree with you that it is probably not the fuser.
If there is no other obstruction that intermittently deviates the paper as it travels then I would have to come back to the paper.
See if they have multiple lot numbers on the paper they have and try a couple of different lots.
If they have only one, go out and buy a ream of 20lb Xerox paper and run it to see what happens.
For me this usually comes back to the paper.

Re: DPC 354 wrinkle

Thanks Doug. I agree. I think testing the paper would be the next logical step.

Re: DPC 354 wrinkle

Try changing the orientation of the paper i.e. portrait/landscape. If both orientations wrinkle, it is most likely the paper.

Try 11x17 paper. Is it during duplex jobs?

Re: DPC 354 wrinkle

Have not duplexed. Will wrinkle from both tray 1&2. Very intermittent. Changed paper orientation from 11X8.5 to 8.5X11. Have not had a wrinkle yet.

Re: DPC 354 wrinkle

Does it have a transport unit on the machine to take the paper to the exit tray or finisher? Had the only clutch in there fail more times than I would like to count.

How many copies on machine? Looking for some sort of burr that the paper is catching on.

Re: DPC 354 wrinkle

The paper exits into the internal tray. Does not go thru transport to finisher. Has 316K on it. When it wrinkles, there is no skew and I looked for a nick on the lead edge of the paper but did not see any. I was thinking it may be the paper. But why then would it be so intermittent? I think I will go get a ream locally and try that.

Re: DPC 354 wrinkle

I have tested the machine for a while with diffrent paper orientation and have not had a wrinkle. Fir the most part, it will wrinkle towards the front and rear areas od the machine. No nicks in the lead edge of the paper to indicate a hesitation. Image in paper is good. No skew. I swapped feed units with another machine and still have the problem. Also used a second transfer assy. from another machine as well. No luck. Does this machine have settings for fuser speed that I'm not aware of? Grasping at straws here.

Re: DPC 354 wrinkle

Is the image folded over on itself so there is a white void when you stretch out the wrinkle/crease? No skew on image, used multiple paper trays and sizes. I'd go back with a new fuser. Wrinkles are usually fuser related if it ain't the paper. Do you do the 120k PM's, maybe the fuser you used has more copies on it than you think. Spring pressure assy out of position. Put a new fuser in and call the customer in a week and see how it's run, no need to sit and keep watching it.

Good luck

Re: DPC 354 wrinkle

OK.
Just a random thought here.
You know how the pressure springs love to break every so often.
What if this is the first indication that the spring is about to fail?
If it was about to fail, then you would expect to have uneven pressure in the fuser.
And if you have uneven pressure, you have wrinkles.
Try swapping out both pressure springs.

Re: DPC 354 wrinkle

Thanks for your response. I just put a new fuser in it this morning. The machine is actually in our demo room. I really think its the fuser. Even though I put in a used one that did not have wrinkling issues from where it came from, using a new one is the best route. Will post results soon. I did notice a giude right below the fuser. You can see it when you remove the fuser. It has a linkage to it. Anyone know exactly what this is? It can swivle. My first thought was to change the entrance to the fuser for thick paper. Looked in the manual and did not see anything.

Re: DPC 354 wrinkle

I'd go with what 20Guage was hinting at, If the there is a white void when you stretch out the paper then it means the crinkle happens before it enters the fuser.

Re: DPC 354 wrinkle

Well sports fans, its official. It was the fuser. I guess just because a used fuser in the field that was not wrinkling paper, does not mean it won't wrinkle in another machine, or in a diffrent environment. Should have gone with my gut in the first place. Thanks to all who responded.
