Problems feeding vu-foil material with LJIIP

My trusty (and ten-year-old:-) LaserJet IIP has recently started playing up (apart from my experience, reported
in another thread, where I had to replace the 27T/21T feed gear on the fuser unit).

Paper feed works fine, both from the LC tray and the MP bit. However, I frequently need to print
vu-foils (OHP acetates), but I'm now having feed problems. The acetate material is exactly the same brand
as I've used for the past six or more years, and I doubt that it's been reformulated.

I *used* to be able to put a supply of sheets of acetate, each interleaved with a sheet of ordinary paper, into the LC tray
and then print two copies of each page. That tidily gave me a legible hard-copy backing sheet of each OHP slide, and also
avoided the problem of the occasional pick-up of two (or even more) sheets of acetate, which gets nasty!

Now I find that, although the acetate prints perfectly, the printer /thinks/ that it hasn't, producing the ubiquitous
Error 41.

So I switched to putting the acetate stock in the MP Tray; again, in the past I've managed readily to put a stack of sheets
in there, and the printer has picked them up and processed them one-at-a-time. Now I find that if there is still a supply
in the hopper, I get the same Error 41 immediately after printing each sheet. (And of course, Alt+Continue reprints the same
page).

My only solution is to place the sheets on the hopper one at a time: it's fine like that. But I *must* wait until each printed
sheet has been fully ejected, and the flashing On-Line light extinguishes, before placing another sheet in the tray: otherwise
I get Error 41 again straightaway.

I'm sort of theorizing that there's some sort of failure properly to detect the passage of the trailing edge of the sheet.

But why?

There are several causes of a 41 error. Most are caused by the lower cassette tray. Try removing the lower cassette tray and printing from the MP tray. See if the problem disappears. HP has a retrofit kit for the fuser assembly. This is a kit to bleed static off the fuser to ground. You could have excessive static from the acetate causing the error. If it consistently works with regular paper, that's what I would suspect. The error could also be caused by early scanner problems. Tough to troubleshoot when you're not looking at the printer. Hope the pointers help.

Is this the one you sell for USD5?

The odd thing is (I think) that the troubles have only started from after my earlier
repair where I replaced the stripped drive gear on the fuser. Could it be that I've
disturbed something in doing that?

Indeed, I can understand that; thanks for your efforts anyway.

I think so; I suspect I need to find some dollar bills to send through the post to
you for one of the kits :-)
