  • Page 69: Ink Regulator Maintenance Procedure

    OPERATIONS MANUAL – 5750440 – REVISION D Ink Regulator Maintenance Procedure Pressure swings (decreasing and increasing pressure from nominal setting) can be caused by obstructions in the valve seat of the ink regulator. Obstructions in the valve seat area may also cause the pressure to creep up over a period of time (for example, the pressure is set at 7 PSIG, and fifteen minutes later it has increased to 9 PSIG).
  • Page 70 OPERATIONS MANUAL – 5750440 – REVISION D Ink Regulator Maintenance Procedure continued H5 Purge the printhead three times. Check the pressure reading indicated on the gauge. The pressure should not deviate more than .50 PSIG from the set pressure. If the deviation is more than .50 PSIG, reset the pressure per steps 10 through 13.

  • Page 81: Theory Of Operation App C

    OPERATIONS MANUAL – 5750440 – REVISION D Theory of Operation Appendix C Mechanical System Fluidics: Ink flows into the printhead from a pressurized “ink can” supply [A]. The ink can is filled to 50 psi which allows it to completely discharge its ink and maintain an adequate supply pressure to the printhead. An ink-pressure regulator [E] reduces the ink pressure to 7-psi for system operation.
  • Page 82 OPERATIONS MANUAL – 5750440 – REVISION D Mechanical continued Printhead Operation Ink flows into the printhead through an inlet filter [E], and into the valve body. The valve body consists of a back plate [F], membrane [N], chamber plate [G], front seal [H] and orifice plate [L]. Ink flows into the chamber plate and is sealed by the piston applying a force, to push the membrane against the chamber plate post [I].
  • Page 83 OPERATIONS MANUAL – 5750440 – REVISION D Mechanical continued Each printhead has seven solenoids to control piston movement. When a piston [D] pulls back, it allows ink [M] to flow between the membrane [N] and through the center of the chamber plate post [I]. Ink flows into the orifice plate and ejects as droplets [P] each time the solenoid [C] is electrically energized.

    OPERATIONS MANUAL – 5750440 – REVISION D Electrical The system consists of three assemblies: the controller, which contains the Motorola 68332 microprocessor-based CPU board; the printhead/driver board assembly; and the 15VDC-power supply. The external 15VDC-power supply supplies the system voltage. The 15VDC supplies power for the printhead solenoid drive, the ink pressure sensor circuitry, and the optional external photosensor.
