I had a similar problem with a HP printer some years ago. What I did was to shut the power off, open the cover and, using a clean, wet rag, wipe the steel rod that the ink cartridge slides along. It get sticky with ink residue and paper dust. Wipe all sides and dry it with another clean rag. (I think I used paper towels). Then slide the ink cartridge holder over to the other side and clean the other half of the rod.

Try to download the last driver from HP (April '09), these solve the same problem with my vista.

C:31:40 is "FG fault when starting drum." In plain terms, the video head assembly is not producing a feedback signal that tells the control circuitry that the heads are spinning. Most probable cause is a bad drum assembly, but check to make sure the flex cable going to the drum is properly seated.
