For example: If the Left = 0, Right = +0.004”, then the center should
be adjusted to + 0.002”. This will ensure a smooth plane of travel for the
carriage assembly. There are no adjustments on either end of the shaft in all
models.
Head Height Alignment Procedure
Perform this procedure only when the encoder strip stabilizer has been
removed from the Y-Arm or whenever the alignment is in question (carriage
head strikes occur or deadband calibrations cannot be achieved).
The head height alignment procedure is to ensure that the correct amount of
distance exists between the cartridge jet plate and the Platen. See Figure
3-14.
