Adjust break-off point
Tools required:
Ƒ Magnifier (eyecup type)
Ƒ Allen key (2.5 mm)
ʄ Before you start
NOTE It is important when making this adjustment that the print head height is relative
to the production height of the print head.
1. Position the head onto the maintenance holster.
2. Start the jet(s) and leave them running for at least 30 minutes.
3. Remove the upper cover and the head cover.
With multi-jet heads, each jet has its own potentiometer (the right-hand pot is for the right
jet, and so on).
ʄ Procedures
4.
The following adjustment is made using the magnifying loop. Look at the jet in front of
the charge electrode (strobe LED) (see figure 1):
Ƒ Start by turning theadjustment screw counter-clockwise as far as it will go. The jet will
now be a continuous stream.
Ƒ Gently turn the adjustment screw clockwise until the jet break-off point is located in
the center of the charge electrode. The break point is correct when you have three full
drops counting from the base of the electrode.
