It is normally an easy repair. You need to replace the
(D-shapped) pickup
roller. Eitehr the complete pickup shaft assembly, or if you want to save
money and do a little more work, just the roller (the latter is what I
always do). It's a common problem on SX printers.
Tony, do you have an EASY source for these rollers? I have 3 or 4 SX
printers that I'd love to donate to some charity, but all have the same
problem. All of them were rebuilt by me (I have some articles written on
repairfaq.org about the HP2/3 and HP4/5) but these rollers are impossible to
be found in Brazil. Most american suppliers - dunno why - do not ship to
Brazil. :o(
