Pressure regulation system for multi-head ink jet printing apparatus |
摘要 |
A regulation system controls the print head pressures of a plurality of discrete ink jet printers of the continuous type to the same nominal pressure, while the printers use a common drive source to their own ink pumps. The regulation system includes bypass pressure detection passages extending from a tap in each printer's circulation system to a detection reservoir. Each bypass passage includes a bladder/valve portion whose exterior is in fluid communication with a detection fluid enclosed within the common reservoir. A transducer detects the pressure of the common reservoir and signals control of the common pump drive so as to regulate all print head pressures to the same nominal operating pressure.
