HP Laser Jet series II; Apple LaserWriter II NT

I have one of each. These are getting up in years; the HP has slots
for the additional font cartridges. I think they are PostScript
printers. They use the HP 92295A toner cartridge.

Both have the same problem - paper jam. The paper will be pulled out
of the tray for a few inches, and then the machines stop. The city
will be having its special pickup soon, and before I stick one or both
out for that, or before I Freecycle one, is there a quick fix for
this? If it's an "everyone knows that one" as opposed to a "could be a
lot of things" problem, I don't mind attempting a repair. I have other
laser printers, so it's not mandatory that I get these running. I
don't have the service manuals for these.

Thanks in advance.

Clean the rollers with solvent such as Acetone... May help. Do this in
an an open environment! (Use commercial solvent, not fingernail polish
remover which has oil in it.)
