MP C4503 Folding Paper

[nokktekk]

Good day. I have an MP C4503 which is folding paper before reaching the registration at random as per attached image. This is occurring when using tray 1. I have swoped the 1st and second paper feed unit assembly problem is still there. The guide plate swivel no.1 is ok. Has anyone ever encountered this issue?

Look at the belts on the duplex door opposite feed station 1. One of them will be sticking. Just put a bit of light oil on the shafts and you should be sorted.

Thanks mate. Will try and do that.

Looks like it is time to replace feed rollers on the tray that is feeding from.

As mentioned above this is a common feed rollers problem you need to replace them as a set.

I have swoped the paper feed unit assembly but the paper is folded from tray 1 only. Tray 2 is working fine. I will change the feed rollers and see what happens.

Buongiorno. Ho un MP C4503 che sta piegando la carta prima di arrivare alla registrazione a caso come da immagine allegata. Questo si verifica quando si utilizza il vassoio 1. Ho scambiato il primo e il secondo problema con l'assieme dell'unità di alimentazione della carta è ancora lì. La piastra di guida girevole n. 1 è ok. Qualcuno ha mai riscontrato questo problema?

pickup roller kit worn, or the duplex door does not close properly, someone may have opened it too much and the metal hinges are warped, (this happened to me by a customer) .... try to keep it well pushed in the lower part with one knee while doing some printing tests

gets my vote, try reinstall the belt turning it 180 degrees. Also I remember there is a bulletin on this with some extra washers or something.

That fault as in centre of paper would be the 3 belt rollers on the main door lower section
