VJ 7Combo Series Printhead
Adjustment PatrionPlus VJ 7COMBO printheads can print a single line of 1/2" (13 mm)
or 1" (26 mm) high characters. The printhead is shipped configured to print
1/2" (13 mm) high characters. By reconfiguring the valve tubing you can
change the print height to 1" (26 mm).
If you want to reconfigure a VJ 7Combo printhead follow the procedures
below.
1) If you are adjusting an existing setup, be sure to flush the printhead
with solvent, turn off the controller, and disconnect the power cable
and data lines.
2) Disconnect the printhead ground wire from the printhead bracket. (See
Figure 3E.)
3) Loosen the four screws on top of the printhead and remove the
printhead cover.
4) If an independent printhead kit is installed, remove the photocell
board.
5) Remove the blank nozzle blocks from the slot.
6) Lift the printhead assembly out of the printhead enclosure, being
careful to simultaneously lift the nozzle blocks out of the nozzle block
slot. (See Figure 3E.)
7) Carefully disconnect the valve tubing from each nozzle—one at a
time—and reconnect the tubing to the appropriate new nozzle. (See
Figure 3F.) Make sure the tubing is carefully aligned to prevent kinks in
the tubing.
8) Replace the printhead assembly in the printhead enclosure while
simultaneously installing the nozzle blocks into the slot. Nozzle blocks
are keyed so there is only one way they can be put into the slot.
9) Replace the blank nozzle blocks in the slot.
10) Replace the photocell board, if an independent printhead kit was
installed.
11) Reinstall the printhead cover and tighten the four screws.
12) Reconnect the printhead ground wire to the printhead bracket.
