While we're on the subject of decaying rubber in an HP85, I would add, don't try
to run the printer until you have opened the unit up and freed off the drive
belts - one for paper advance, one for print head. These belts go sticky and
stick to the pulleys, so that when you try and run the machine they tear
themselves to bits.

It's a pity you weren't here a few months ago - a number of us got together and
bought a bulk order of replacement belts very cheaply. I still have a spare
pair if you're desperate, and I imagine one or two others may.

FWIW the teeth on these belts are pitched at 0.080 inch - the standard "mini
pitch", unlike some equipment I have which uses belts with the teeth at 0.081
inch...

Philip.
