PTD55 SERIES OPERATION MANUAL
5.1 - ADJUST
ING
THE
CUTTING POSITION
BY COMMAND
3.1- To adjust the distance between the black mark and cutting line, the PTD55 provides the
standard command
GS ( G nL nH mL mH
, where:
hexadecimal
GS ( G
: 1D 28 47 → Command head (Always fixed).
nL nH
:
A8 02
→ Total length of the ticket in dots (
Always fixed
).
85 mm = (85 x 8) dots = 680 dots
680 decimal = 02A8 hexadecimal
mL mH
: 1C 00 → Offset distance in dots between the top of the black mark and the next
cutting line of the ticket in the feed direction (
Variable depending on
the preformed
).
As it indicated above, the fact that there are different preformed, as well as mechanical tolerances
and mounting, causes the
mLmH
distance is variable.
An example of trial-error adjustment is shown:
1.-
For the preformed shown in the image,
suppose that you start by
mLmH
= 1C00
value and
the cut has exceeded the desired line (in red).
2.-
In a second attempt, decreasing the
value of
mLmH
= 0200
, pruduce the opposite
result. The cut occurs before the desired line.
3.-
Therefore, by selecting an intermediate value
mLmH =
0800
, the cut is achieved in the right
place.
