There is a screw on the left side of the guide. Remove it and pull
your guide forward to remove it. Gently now as it is only plastic.
Check for any pieces of paper and dust build up. Clead the area and
you will also have the rollers exposed. Clean the rollers while your
at it. Replace the guide and try it again. The HP 4 series were always
a bit touchy when they get dirty. Other than that, they make a nice
print.

This HP 4MP prints nicely. Intermittently the paper will jam in the
following position:

The paper never jams if it is fed through the manual slot. I have exchanged
the oblique roller with one from a working machine and it still jams
intermittently. When the jam does occur, the paper is always stopped in the
same position. There are no unusual noises that accompany the jam. Any ideas
as to the solution to this?

Thanks for your reply.
