Integrated Valve Section 7: Troubleshooting Setting Ink Pressure Ink pressure must be set within specifications using an ink pressure gauge. Lowering the ink pressure to alleviate print head seepage may result in performance and reliability problems. The I.V. design relies on the equilibrium of ink pressure, pre-load, and pulse width.
Integrated Valve Section 7: Troubleshooting Ink Regulator Maintenance Procedure If print dot size is fluctuating , check the print head pressure. If the dot size fluctuations can be correlated to changes in ink pressure, the ink regulator may be in need of service. Dot diameters will decrease if the regulator input pressure is less than 2.0 PSIG greater than the print head pressure (6 PSIG).
Integrated Valve Section 7: Troubleshooting Print Head Pulse Width Adjustment When a print head solenoid is on, the piston pulls away from the membrane, ink pressure moves the membrane away from the orifice, and ink is expelled through the orifice to form a dot.

Integrated Valve Appendix B: Theory of Operation Appendix B: Theory of Operation Functional Description The IJ3000 ink jet system prints text, autocodes (such as product counts or time and date stamps) and/or graphics onto products as they travel by conveyor past stationary print heads.
Integrated Valve Appendix B: Theory of Operation Encoder The encoder determines the time period between the printing of individual columns, or the print speed. As a product's speed increases, the time period between columns must decrease, that is, the print speed must increase, to maintain consistent column-to-column spacing.
Integrated Valve Appendix B: Theory of Operation CPU Board The CPU Board has two microcontrollers, an LCD controller, flash memory, SRAM, a real time clock/calendar, an Ethernet port, two serial ports, 12V, 5V and 3.3V regulators, a 3V battery, and PC/104 bus connectors. Of the two microcontrollers, one (U13) is the IJ3000's central processing unit (CPU).
Integrated Valve Appendix B: Theory of Operation I.V. Print Head Interface Board The I.V. Print Head Interface Board controls the print head daisy chain, and it is the power entry point for the print heads and the rest of the system (See the Power section above.) The Print Head Interface Board also contains the photosensor and external encoder con- nectors.
Integrated Valve Appendix B: Theory of Operation Ink Delivery System Features The Ink Delivery System (IDS) provides ink to the print heads. In addition to pumping ink from the supply container, the IDS is programmed with the following features: 1. Continuous monitoring and maintenance of ink line pressure. Whenever the pressure drops to a level of 20 psi, the IDS pump turns on for five seconds and the pressure returns to a level between 23 and 27 psi.
