It seems the best way to use the R280 that I found was this:
- use stock ink and the DVD tray
- prep the PCB with a brillo pad, and alcohol wash/wipe. Then heat it up just
before printing, this will drive off any excess water.
- you must fool the printer with a paper CD in the tray, just lay the small
copper blank on top. use adhesive tape to hold both in place. This does require
the tray to be modified to hold the PCB.
- print from the CAD program onto the copper
- immediately dust with printer toner, and gently blow off excess.
- fuse the toner with a short warm-up on a hotplate, you'll see the toner fuse.
- etch
