Hi,
both of my 82341A printers now suffer from a poor paper advance function. I disassembled one printer (which otherwise shows no defects or problems) and pulled the pinch roller (9) and the paper advance (16).
The rubber wheels are not very soft anymore even though I rejuvenated the rubber with CaiKleen http://store.caig.com/s.nl/it.A/id.1671/.f?sc=2&category=179one year ago. Otherwise they don't look too bad.
I measured the diameter of the wheels: d_out:7.86 mm, d_in: 5,22 mm. The width:2,11 mm.
The Roller pinches look pretty worn out, at least one of them.
The diameter d_out is: 4,38 mm. The width is 2,11 mm.
I guess that those values might sound somewhat more reasonable, if expressed in imperial units. How would that be expressed in inches?? 1/20 of an inch or something like this??
Does anyone has the hp specification, the original values of the wheel and roller?
And.. more important, does anyone knows replacements for the items, or can point me to an article where someone has explained how he made a replacements?
Thx!
