Digital ink-jet printer, uses compressed air to project droplets from ink reservoir with capacitive level detection and with adjustable orientation of ink nozzles to control print quality

摘要

The ink jet printer has a pneumatic circuit with a source (A) of compressed air housed in a fixed control bay (2) in the printer, a pre-set adjustment mechanism to control resolution by orientation of the print head (14), an ink reservoir (13) including an anti-wave device and a capacitive ink level detector (18) external to the reservoir, and a cleaning station (24) for the print nozzles.
