Hi
Before oiling I would check if paper is properly positioned with the right side on top. Check also if plate which pushes from the back to the paper at the place were the printerhead moves back and force can move freely (is loaded with a small spring) and the linnen like stuff is in place and not sticky. Difficult to see, but use a magnifier glass and you probably can diagnose.
If no succes, open drive and see if rubber belt is not slipping.
Third: a miniscule drop of oil on the bearfings of the electromotor axle and last a snuff of teflon enhanced grease on the spiral axle and bearings which drives the head.
Whatever you do, be very carefull, the printhead has a couple of thermistors in the surface which actually make the dots and these are very sensitive, before you know you end up with a smoothly running, but not printing printer. Never-ever remove the printhead itself unless you are real brave. I found out the hard way one time.
Please feedback your results to the forum.
Succes
Ronald

The motor drives the printhead via a small rubber belt. Over time the belt stretches and begins to slip. Also dirt and paper dust in the drive screw can gum up the works.
