5.1.1.9 Parallelism Adjustment
Parallelism adjustment is to adjust the distance between the nozzle plate
surface and platen, setting the thickness gage to the both edges of the
carriage running range, which the carriage can move, and to secure that
distance.
If this adjustment is not performed correctly, problems such as dirty printing
or partial ink dry printing, or no contact between the head surface and the
cleaning blade occur. In the worst case, the printer may go to the carriage
error. Therefore, make sure to perform this adjustment at the following
conditions.

Reason/Background
Even if you make a mark to the
position of the parallelism
adjustment bush before
disassembly, it is still necessary
to perform this adjustment(if the
left conditions apply), since
precise assembling difference
occurs on the process of
assembly.
Step1. After removing the upper case, insert the A3 exclusive glossy
paper to the rear manual feed slot. As an actual method to,
insert the paper, pull out the iron part, which is pressed by 7
tension wires to the reverse rotational mechanism, toward
you(in other words, toward print rear direction), and push the
glossy film until it stops in the position between the paper
load roller and paper feed support roller at the same time.
