MP C2051 When printing in A3 you make stripes, but not when copying.

Re: MP C2051 When printing in A3 you make stripes, but not when copying.

That is the reason to draw on experience and expertise, for a second opinion of copytechNet's technical colleagues.
If I already do the tests, which I explain, and I can not isolate the failure, obviously I come here to try to see different points of view to raise the incidence differently.


I understand what you mean, the coherent and correct thing is to change old pieces for new ones. (the new ones I already indicate in a previous post)
But the changes became provisional, since it was very difficult to isolate the specific piece that generated the defect (the stripes). And I repeat, not the fact that it makes noise, but the one that caused the stripes that I teach in the links, strangely related to noise.
All the changes were made with parts of a machine in perfect condition and so to speak, I have all the parts of the client in the test machine of the workshop and it has been IMPOSIBLEM to recreate the defect, and the client until a few days ago the failure persisted, currently the client's device, no longer generates such stripes, which has no explanation since no more changes have been made since the tests and consultations made here began. Only the fuser noise remains, which has already been solved with a change of the fuser sleeve.


I repeat that I appreciate all the help.

I remembered, months ago, on that model, I had a similar problem, caused by the ITB contacts on the machine body
