Dig around HP's web site.  I don't think they have complete manuals, but
there is
a lot of information on their site.

For printers that have seen a lot of use, the rubber rollers degrade. 
The printer
will start to feed a page, but it won't go anywhere.  The roller can't
grab the 
paper and the printer detects this.  I know on the HP 4si, they
recommend 
installing a maintenance kit every 200,000 pages.  This is a fuser and
roller
replacement.

Most (all?) of the HP 4/5 printers use 72 pin FPM simms.  Sometimes they
are picky
about the ram.  HP should have a memory compatibility chart on their web
site.

The memory should be cheap.  I would max it out.
