Iris ink jet printers were responsible for the first (and some say still the best) giclee prints. Four precision nozzles were at the heart of the printer and this device was the best way to clean them. It used the vacuum system of the printer to flush the nozzles without damaging their 2 picoliter droplet production. Made of composite material with a magnetic base, this item was a hard-to-find accessory for those legendary printers. In working condition.
