* When [↑], [↓], [OK], [EXECUTE] button, [COLOR], or
[BLACK] key is pressed, the data are saved to EEPROM
and RAM.

ton is pressed during printing, the operation is interrupted.
* When the machine returns to the ready state after occur-
rence of an interruption, self print is resumed.
4) Check the adjustment pattern image position.
Measure the dimensions of void area in the right and the left
frame direction of the adjustment pattern to check that the
dimensions are as follows:
If DEN-C = 3.0 ± 2.0mm and DEN-B = 3.0 ± 2.0mm, there is no
need to adjust.
If the values are as shown above, there is no need to adjust.
If not, go to step 5.
5) Change the adjustment values of A (DEN-C) and B (DEN-B).
When the adjustment value of A (DEN-A) is decreased by 1,
the sub scanning direction print start position is shifted toward
the paper lead edge by 0.1mm.
When the adjustment value of B (DEN-B) is decreased by 1,
the paper transport direction print range is extended toward
the rear edge by 0.1mm.
6) Repeat steps 1 to 5 until the conditions of step 4 are satisfied.
Default
value
30 Adjustment value to fit with the print lead edge for the printer.
When the adjustment value of this item is decreased by 1, the
printer print start position is shifted toward the lead edge in the
paper transport direction by 0.1mm.
20 Void quantity formed at the paper rear edge. When the adjustment
value of Item B (DEN-B) is decreased by 1, the sub scanning
direction print range adjustment value in the paper transport
direction is decreased by 0.1mm.
20 Adjustment of void quantity formed at the right and left edges of
paper. The greater the value is, the greater the void quantity is.
