Yes isnt machine intelligence wonderful, the 900 OTOH, optically
detects a notch and a white square printed on the tray, not the disk.

I have tried standard 1.6mm copper fr4 about 1/3 of a cd size, inthe
cd cutout/indentation, worked fine, just ink wipes off as I have dye
ink cartridges.

So, printer fine, economy inks no good, maybe if I bought a $55
durabrite cartridge it would do PCB 'off the shelf'
