There are five different carriage movement buttons in the
adjustment program: PG jig setting position movement, PG
right main shaft adjustment position, PG left main shaft
adjustment position, PG right sub shaft adjustment position, PG
left sub shaft adjustment position.
"
If the Release lever is in the release position, pressing the button
for movement to any adjustment position will cause an error.
Therefore, always place the Lever in the PG + position
(envelope mark position).
"
If PG adjustment cannot be made within any Adjust parallelism
bush adjustment notch range, change the setting positions of all
Adjust parallelism bushes to the center position and make
readjustment in all adjustment positions.
13. After the PG main shaft (left and right) and PG sub shaft (left and right) have been
adjusted, print the check pattern. This pattern is used to check for parallelism
between the CR main shaft and sub shaft. If the gap and overlap between the
blocks are within 0.18mm, terminate the adjustment. If the gap and overlap are
more than 0.18mm, execute Steps 3 to 11 again.

Before printing the PG adjustment check pattern, you should
have terminated the Bi-D adjustment and Head angular
adjustment.
If these adjustments have not been made, the displacements of Bi-
D and Head angle are reflected on the PG adjustment pattern,
and PG adjustment results cannot be checked completely.
