A word of caution on replacing parts on these SX printers: when you
reseat the connector for the main motor to the DC Power Supply, make
certain the snap connector 'snaps' and that it isn't doesn't feel
'mushy' or you may discover you have a false main motor error (error
code 54 I believe) after having buttoned up the printer. Reseat the
connector at least twice. Before replacing the top cover power it up,
there are no interlocks involved and you needn't have the control
panel attached to run an engine test. On the left or right side (I
forget which side) bottom of the HP II you will see a hole about 1/8"
in diameter. If you press the rubber membrane covered microswitch
inside the hole the engine test will run and print a sheet with finely
spaced parallel lines running longitudinally on the copy. This will
verify the main motor connector was reseated properly and that the
feed roller was replaced properly.
On an SX (HP II, III, IID and IIID) engine always reseat these snap
connectors prior to replacing parts such as the laser scanner (reseat
both at the scanner and dc controller, and all sensors at the dc
controller.

Ya know.. this is what I get for even *dealing* with our MIS
(Mostly Incompetent Shi*theads) dept... you'd think after 10 years
with the same company I'd learn... I should have researched the
roller prob myself....
Anyway... I'm going to offer to take all those 'dead' HP IIs off
the company's hands, and then *fix* the damn things, and **sell**
them... or trade them for Stuff... the last time they dumpstered
a whole storeroom I got tons of swappable Stuff.. woo hoo! I love
Surplus!!
Thanks VeryVery much for the roller and parts supplier info..
Cheers
John
