"It works fine on our other computer"
This would seem to limit the problem to a computer or user account rather
than the printer.
I'd likely try uninstalling the printer driver on the PC with the problem,
and reinstalling a "known good" version if possible.

The memory replacement/addon would be suspect if the printer did not work
correctly with another PC.

Just yesterday our 5si started having a problem with multiple page print
jobs. When you print a multipage document, it prints all on top of each
page
on one sheet of paper. Five pages of text would print on one sheet of
paper
each page over the last. It works fine on our other computer. THe other
night, I installed automatic updates, any chance this could have created
the
problem? Also, yesterday we installed more memory but it printed fine
yesterday and now when we turned it on today, problems! Can any help?
