Digital Sign Technologies (DST, Mississauga, Ontario) has released the newest model in its flagship Print Head Doctor print head cleaning machine. Print Head Doctor 14 (PHD14) comes with high-performance Swiss pumps by KNF Neuberger, allowing the machine to reach higher flow and pressure. The XL version allows it to clean up to 6 print heads at once. PHD14 can ‘recover’ several print heads at a time – for example, two Kyocera KJ4 series heads or six Dimatix S-Class heads. It also has reverse-flushing capabilities, electronically controlled pressure and fluid temperature, and two-stage filtration with a total of 6 filters. Adapters are available for most types of inkjet print heads, and the company offers a range of recovery chemicals for UV curable, solvent, eco-solvent and water-based print heads.
