After 10 or 11 months of xp problems an a number of different printers rendering far less than quality prints. Thinking those past problems were resolved I installed the ipf 5000 last Friday with the guidance of a canon tech.
I ran several test prints using most of the different settings on the printer. The paper is Domtars Nekoosa Lenin, {the paper has a slight texture} Cathy's Profiles told me a custom profile would not solve the white specks problem, they said it sounded like a printer problem.
Some of the folks on Wiki have said these tiny white specks may be caused by dust on the paper adding some of the dust might be getting in the printer causing slippage resulting in some of the photos not printing stright. I don't think this is the 1/8 margin bug, may be somehow though. The top of the photos that have not printed straight measure 4" wide at the top and the bottom of the photo measuring a 1/32 of inch more give or take than the top width measurment. the left side of the photo is stright top and bottom, it is the right side bottom right side of the photo that is printing incorrectly for what ever reason. Please help if any one has encountered these issues printing with ipf 5000; found the reason and resolved ether of these problems. KSG
