I've had the Officejet 8040 for about a year and it just started having loud grinding/slightly squeaking sounds with every print job. I know you can't lubricate the mechanics, I've lightly wiped off parts but with no success. I've tried different types of paper but with no success.
Not sure if there is a way to recalibrate to see if that might work (no clue how to do that) but wondered if anyone has any ideas or has experienced the same. Many thanks. John
