There are a wealth of
info
there.
Some of which I contributed to. My first laser printer used a Canon CX engine. I was
given it because it
didn't work, it took me an hour or so to find a dead PAL (actually a HAL)
on the formatter board. Canon didn't sell spare chips, they wouldn't even
sell be the complete board. And they wouldn't supply a service manual.
(This was before I'd found The PrinterWorks, who would at least sell
mechanical bits and complete boards).
Oh, you are the one of the CX crazy printer, you are a god! :oD
Anyway, a few years later, I bought (cheap) a Apple
LW2NT (SX engine). I
did much the same with that. Took it apart, figured out how it worked,
and made notes. I use that printer on my PC to this day....
Same here, I have a Laserjet III (which I don't use anymore) and a 4
Plus which I did the same
Many of the laser printer repair books and stuff on
the web are
downright wrong. Others simply encourage lucky-dip methods. I've yet to
see one that really goes back to first principles and tells you to start
by checking signals, etc.
Well, this is a deeper level that me and you may understand, but what
about the John Doe with error 50 on his HP3? I fixed **lots** of HP3 with
just changing that (insert your preffered expletive here) thiristor, and
giving a good cleaning and resolder of contacts as I stated in my part of
the text
Great printers, but I'd love to have a 5 Plus :oP
