Laserjet II/Canon SX paper jams

The printer is actually a Gestetner GRX820, however it uses the same Canon
SX engine as the Laserjet II so I thought more people might read this post
if I mentioned the LJ II in the title.

When picking paper from the tray I always get a paper jam. The leading edge
of the paper has only moved about an inch into the engine. However, if I
feed paper from the manual input it always feeds correctly. What does this
indicate?

I know the printer is old, but it hasn't done many prints (<50,000) and it's
cheaper to run than my inkjet so if I don't *really* need colour I'd like to
go on using it.

All ideas welcome.

Thanks

Doug

You have the classic paper pickup failure problem. Most likely, it is a
worn paper pickup roller and/or a worn paper separation pad (little cork
thing).

You can see diagrams of this stuff at http://www.printerworks.com
and you might be able to buy the parts at www.fixyourownprinter.com.

The original high quality pickup rollers are no longer available, and
you end up with some cheap clone rollers that don't last as long.

50,000 or so copies is what people used to commonly quote as the life of
the pickup rollers and separation pads.

rg1-0931-060 or ra1-3851-000 are pickup roller numbers and fr1-1145-020
is a separation pad number in my arts box.

C. Hoelzle Associates in Irvine CA 949.251.9000 might be able to help.

Find old printers HPII or IID or III or IIID to use for spare parts.
Most of the parts interchange.

Six months ago, I trashed three such printers. Heavy old things.

You can also buy some "paper jam" repair kits for printers on ebay-
Fairly pricy when you add in the usual high cost of shipping, and no, I
don't know if they have good rollers in them or even good separation pads.

Thanks, Jim

I'd tried cleaning the pickup area and suspected that as that hadn't worked
I probably needed to replace the roller. It's nice to have this confirmed.

I managed to source the parts locally (UK) and paid about GBP8 for the
roller and separation pad. It took me about an hour to replace them as there
was a bit of head scratching involved trying to work out how to get the
shaft with the roller out of the engine. Once I realised that the metal
panel across the front had to come off and that the DC power supply had to
be removed, it was quite easy.

Anyway, it worked. I now have a printer that is feeding paper again. Here's
to it lasting another 15 years! Thanks for your help.
