Workcentre 7120 Continuous A4 Paper Jam

[tilekt]

Hi all,

Please, share your experience with resolving an issue with Workcentre 7120 where we are experiencing continuous jamming of A4 papers.

We have 2 trays of A4 papers (trays 2 and 3), and 2 trays of A3 papers (trays 1 and 4). And almost everytime (9 times out of 10) A4 papers get jammed in various areas like just before the output, or at the tray exit, or in between.

And we don't have any problems with printing A3 papers.., sometimes when we have to print many pages (like instruction manuals) we choose A3 paper with 4 pages on each sheet (double-sided), and never experienced any jam.

A week ago we replaced all of the rollers which are at the trays.

Any suggestions are welcome.

Thanks in advance,

tilekt.

Dear SandyP,

As explained, this is not a single occurrence to which the product KB gives a solution to.

Therefore, the issue is still open.

Thanks for the support.

Having the fault codes would help.

Well, people, thanks for your time, and willingness to help on this case.

After digging in and out this case on the machine, we finally reached to the conclusion that the machine is just too old.

So, we replaced some parts on the machine with parts from another (newer) one, and now we see A4 papers jamming less often.

What was replaced:

1-) "A" Cover Assembly (completely);

2-) Assembly with a Switch which senses the paper jam behind "A" Cover;

3-) Assembly with a Switch which senses the paper jam between "A" and "B" Covers.

Thanks again for your time, people.
