PRINT HEAD DISASSEMBLY AND CLEANING
The print head has a mesh filter screen installed inside. If flushing the print head
does not produce an acceptable code and the unit is difficult to prime, the screen
may be blocked. Ultrasonic Cleaner (Part #42082-01, an optional purchase) is
recommended to assure thorough cleaning of print head parts. Release the
hanger mount spring and remove the hanger mount bracket. Remove the array
plate and the ”O” ring below the array plate.
Remove the (4) screws holding the back plate to the nozzle module. Remove the
screen, screen plate, and rear ”O” ring from the manifold. Remove the manifold,
rear manifold seal and plate from the back plate.
Refer to the illustration on the next page which shows an exploded view of the
print head and the parts mentioned above and earlier in this section.
