Hi, I have a client which as a LJ 1200 printer. Last week he called me
stating that the printer was printing slightly on a diagonal axis. I
then proceeded to replace the Paper Pickup assy, the transfer roller
and the pickup roller. The paper pickup assy comes complete the bottom
plastic assy, the feed rollers, the registration assy... etc.

Today, he called back saying that the paper is exiting correctly,
everything printing parallel to the page as it should, but had another
problem now. What happens is that whenever they send a batch of cheques
to be printed, the first 10 print ok, but from the 11th up it prints
slightly upward of where it should. What could be the culprit here?

I assume the cheques are 3 or 4 to an A4 page (A4 assumed from your spelling of
the word cheque).
Since a printer of this type treats every page individually I struggle to see
how this could be a printer problem unless there is a very weird issue with
registration. I can only suggest a test by generating a document in Excel, Word
or similar that has a horizontal line on it, make the ducument 15 (say) pages
long with an identical line on each page in exactly the same vertical position.
If the printer consistently prints this without any vertical shift the problem
almost has to be software or configuration of the document in the application.
The client may tell you that nothing has changed in the application but if I
had a dollar for every time I have been told that and it turned out to be
incorrect I would be very rich indeed.
Is there any way that a different printer can be used temporarily to see if the
problem is printer related or otherwise?

Alright Tony, I'm honestly not sure what the paper format of the cheque
is, but one thing is sure, there is only one cheque per form. The
reason for this is they need to have a "stub", they call it, for
tracking purposes. I will try a test in Excel or Word, and see the
results.

As for my spelling of the word "cheque", yes, indeed, it's spelled in
french (I just assumed it was spelled the same way). But I'm french
canadian (not from Quebec, thank god), and we use Letter, not A4 as in
Europe.
