    I was just given one of these dryers. Any information would be useful.

    Hi, these can be useful to dry fiber paper flat (not needed for RC paper, as it doesn't curl.)

    I had problems when drying glossy fiber paper face down against the plate. The paper stuck to the plate. Apparently using a hardening fixer may help avoid the sticking. Advise not drying face up against the cloth, as dust and other stuff can get embedded in the paper emulsion.

    edit: disregard my comment, I had a different kind, with a metal plate

    Got one and still use it. Set temp control to 1/3rd of max, use a good ferrotype wax or furniture polish SPARINGLY. The chromed plates have to be pristine. Any rust can be removed chemically using an acid bathroom cleaner like CLR containging hydrogen chloride. It is VERY important to let the chemical do the work, as rubbing anything on the plate except a soft cloth will scratch it and impose these scratches on the finished print. (not even paper towels).

    Hello All,

    Recently (relatively) I have found that Renaissance Wax (used SPARINGLY as stated above) makes a great replacement for the old Edwal ferrotyping wax.

    Thanks for the info on the wax. But I still don't quite get how to use it.

    Roto drier instructions

    Plug it in, adjust thermostat.
    While it is warming up, wax the drum/plate.
    Warm up stage complete in 10-15 minutes.
    Open canvas belt by rotating drum.
    Place wet, (do not squeegee), print on canvas image side facing drum.
    Roll drum (and print) together.
    Using a squeegee lightly press print against drum to remove bubbles.
    Wait for print to dry. Depends on temp, humidity etc.
    When print is completely dry, it will "POP" off the drum when unrolled.
    Finish will be ultra glossy. Be carefull not to bend print.
    All done. Ready for next print.
