Operation
The following operation is used to align one cartridge with respect to the other in the XĆaxis
(media axis). (YĆaxis and ZĆaxis realignments are done by varying the firing timing of each
nozzle resistor.)
1 The stepper motor presses up on the lower link of the three adjustmentĆlinkage pieces by
means of the plastic actuator pressed onto the motor shaft.
2 This action lowers the top link of the adjustment linkage.
3 The carriage moves, and the adjustment cam, which comes into contact with the top link,
is rotated.
4 The cam action causes the adjustable cartridge chute to move in either the plus or minus
XĆaxis direction relative to the fixed cartridge chute.
