I have been having some issues with a D125. While printing large PDF files the file cancels itself. Sometimes I can have a 400 page PDF to print 3 sets. 2 of the come out OK and the third is missing pages.
Also it could be printing and when you check the document is missing pages without any previous error or message.
I have tried sending smaller files and get the same problem every now and then.
Any ideas what this could be?
