My HP 4600 started printing black blotches over everything I print this morning, and I have an important presentation that I need to get published.
I opened the printer, and I do not see any obvious problems, or toner leaking. It seems MUCH worse if I use double sided mode.
Any ideas of where I should start? I only have one set of cartriges for it, and they are remanufactured, but it didn't do this yesterday and they are relatively new.
I attached a scan of what the Print Quality wizard printed in .pdf format to this post
