That is a bit unusual, I would expect it on scans and copies but not prints, or the other way around.
This would point to a bad/failing logic board inside the printer, which may be damage from a power surge, but could also easily be just age related failure.
Realistically, it’s probably time for a new printer. As this is a 2005 model printer, it is well past its 5 year service life, so this type of failure is not surprising. While it can be fixed, it is not worthwhile to do so. If the logic board is bad you’re looking at $200-250. For the same price, you can replace the entire machine with a brand new model, with current technology and a fresh warranty, which makes more sense than buying the new part for an older printer.
I can help with finding parts or recommending replacement options, if you'd like.
