102619 2002-12-02 00:46:00 This printer will run fine for weeks and then start to print rubbish, appears to only have problem when connected to any computer with Gigabyte Motherboard, This is also a network printer. Have reinstalled driver etc Any suggestions. Op system = win 98 gregor_nz (2666)
102620 2002-12-02 01:23:00 "connected to any computer having a Gigabyte moitherboard"; "also a network computer" ?:|

Is it connected to one computer, and receiving files from other computers (by way of an Ethernet cable) some of which have Gigabyte motherboards? Is it moved around from one computer to another, being a network printer on whichever computer it happens to be plugged into?

What sort of "rubbish"?

Serial or parallel connection?

Sorry, it's a bit hard to diagnose with "no" symptoms. :D

102621 2002-12-02 01:36:00 its possible a printer wont go with a certain mb.

still do a virus check first, the recent bugbear/oplsrv virus can disrupt printers.

if someone wanted to hear my sad story with a certian printer,
just keep reading to get bored.

about two years ago, I setup a kyocera FS-1000 with a computer based on asus p3v somthing. the problem is that it wont always print, and freeze the system.

I raised this problem with asus-tech-support and kyocera-au. asus initially acknowkdged there is problem with that particular mb's printer port, some rework needs soldering some diode. the kyocera tech proudly told me that kyocera printer works with any mainboard.

we replaced the mb with a new version. it is running fine for two weeks. then the user called again that he still got that problem.

the kyocera ppl here tested the printer again, printed hundreds of pages to prove the printer is ok. and charged us for the service.

we replaced power supply and everything as we possibly can change in that system. we switched mb to Intels. it went alright for another two weeks. then I heard the dreaded call again.

in those desperate days, I even suspected that the user's electrical mains is not grounded properly.

102622 2002-12-02 01:44:00 when i have run the printer off a compact machine it runs sweet. It is only when it is connected to a computer with a gigabyte motherboard that it goes faulty.

This printer is shared on the network, ( server win 2000) and the clients print to the printer out of profax.

It is connected via the parrell port.

The rubbish is random characters and it just keeps running untill powered down. If uninstall drivers and reinsatll the printer still prints rubbish.

The only way to stop this is to move the printer to another pc, so at least the users can resume printing.

102623 2002-12-02 01:55:00 This could be a problem with a particular parallel port design. I believe that some of the modern "improved" interfaces don't give a full "5V" for the high level. This has given problems with some PIC programmers, and could easily give problems with a printer which assumes that it should get voltage levels in accordance with the "Centronics standard". (It's a long story ... IBM used a bad design for the printer port in 1981, so it's not the "standard" which had been used for years and worked well. :-()

I suppose that it is preferable to have the printer on a particular machine ... so the only fix might be to get a plugin card with an extra printer port, assuming that a separate card would have the standard levels. It's certainly worth a try.
