Flat bed laser printer

    Hi,

    I have searched the forum that some people print PCB traces directly
    with a flat bed plotter. Does it exist a flat bed laser printer that
    can do the job?

    Thanks!

    I would be very surprised to learn of anything commercialy available.
    What would hapen to the static charge on the light sensitive drum when
    it comes in to contact with the copper? By that stage, it may have
    already passed the toner on to the copper, so maybe that is not an
    issue, I don't know.

    It may be possible to modify an inkjet printer to do this. It used to
    be possible to buy inkjets which would print diectly on to CDs, but I
    am not sure where you would get waterproof inkjet ink from.

    Modifying a typical laser printer with its convoluted paper path would
    probably be impossible.

    I get satisfactory results on an hp2200 laser printer with OHP
    transparrencies. But I have two toner cartridges, one for frequent use
    with documents and stuff and one brand new kept just for doing PCBs

    Some copy machines were made with a straight paper path and tha
    capability of handling very thick paper (cardboard).
    These have been used to put toner directly on copper PCBs prior to
    etching.
    There was at least one model that Xerox made when copiers were fairly
    new (and s l o w by present standards), and i understand that Lexmark
    has made copiers/printers like that in the past few years.
    Hope this is of some help.
