It could be a similar problem to one I had with a 890C. With that the print
head drive motor was getting worn and stiff; the clue came when printing the
self test page where it would stop while printing test bars at the top of
the page.
Physically moving the head along with the printer switched off would feel
very stiff too.
I half cured it (it's about on its last legs I'm afraid) by lubricating
(with 3-in-1 oil) the print head guide rail and dropping a few drops down
the top and bottom of the motor shaft, having removed it from the printer
first of course.
That was about 2 years ago. Its still going along OK, but struggling.
