[Function]
Correcting the leader position of Black mark paper/ label paper
[Code]
<1D>H<41>H<m><n>
[Range]
0
≤m≤255
0
≤n≤255
[Outline]
[The specification which is common to the model]
• This command sets the leader position of Black mark paper/ label paper in terms of correction value set for
the default position.
• “m” denotes the correcting direction.
• “m” is valid only for the lowest bit (m0).
• Control by the lowest bit (m0) is shown as follows:
m0
Correcting Direction
0
Corrects the leader position in the forward direction
1
Corrects the leader position in the reverse direction
• “n” denotes the correction value in units of n/203 inch.
[Caution]
[The specification which is common to the model]
• This command is valid only when Black mark paper/ label paper is chosen.
• This command is ignored except immediately after the execution of a Black mark/ label positioning command
(FF, GS FF, GS A, GS <) or immediately after leader positioning performed on a paper feed action with the
FEED switch, power on, or cover closure.
• The maximum reverse correction span is 0.5 mm. Correction settings exceeding this value are truncated into
the maximum value. The leader position may be deviated due to paper flexure. For reverse correction,
exercise care so the leader position does not step out of the Black mark/ label.
• For forward correction, set the correction span by taking into account the Black mark/ label length as the
printable area changes before and after correction setting.
• In calculating a correction span, use the basic calculation pitch (y) for the vertical direction. The fractional part
contained in the calculation result should be corrected in units of the mechanism’s minimum pitch, with the
remaining fractional part truncated.
