QMS 2560 prints only half of faxed pdf files

I have a very strange issue with my printer.
It prints all kinds of files with no problem.
Most PDF files go in and out no problem and print beautifully. But the
minute I try to print out a faxed PDF or a Scanned document in PDF it
goes all weird. And by that I mean that it only prints the right half
of the page and leaves the left half unprinted.

Any ideas what could possibly cause this? Maybe a lack of memory? not
sure.

Thanks
