Drop Generator
The Drop Generator contains the Resonator Probe and temperature sensor. The Resonator probe
oscillates to break the stream into uniform drops. Each Printhead is calibrated with the modulation
voltage, band, charge, and pressure at the time of manufacturing, which is noted on the Controller
Settings Label.
The modulation voltage, Ink viscosity, band, and ink pressure must be correct, ensuring the drop breakup
point occurs in the charge electrode slot. If the drop breakup point occurs outside the slot, incorrect
charging of the drops will occur.
Nozzle
The Nozzle helps determine the drop size printed.
Charge Electrode and Strobe
The breakup caused by the Drop Generator is calibrated to occur within the Charge Electrode slot. The
Charge Electrode applies a charge to drops required for printing. Those drops that do not receive a
charge will be returned to the Ink system for re-use through the gutter.
A strobe LED situated underneath the Charge Electrode allows the drop breakup to be viewed with a 10x
or greater magnifying eyeglass.
Phase Detector
The Phase Detector provides feedback that the drop charging is occurring correctly. The drop charge
timing is critical to the operation; thus a feedback circuit is required to ensure this timing to maintain
optimum print quality.
Deflector Plates
The Deflector Plates generate an electrostatic field. This field deflects drops by the amount of charge
they received at the charge electrode. Drops with a greater charge will be deflected further than those
with a lower charge. Drops that do not contain a charge will not be deflected, passing instead through the
electrostatic field to the gutter for re-use by the Ink system.
Gutter
The printhead Gutter collects non-charged droplets and delivers this reclaimed Ink back to the Ink
system for re-use. In the event the gutter is not collecting non-printed drops during the printing process,
the Gutter Sensor will detect a fault and display an error screen.
Printhead Valve
The Printhead Valve is a three-way valve that:
•
Turns the Jet on / off
•
Opens and closes to allow air to be purged from the Printhead at startup.
•
Opens during a “Backflush” sequence to allow solvent
to be pulled in the reverse direction thru
the nozzle to clea
r/remove debris or obstructions and during the “Stop Flush” sequence at shutdown.
