Chapter 8 Print Unit
When using peel-off operation, the labels would drop from the
backing paper and get stuck on e.g. the table if you use a Start Adjust
value as large as -175. You should rather use a slightly smaller value
so the rear edge of the label remains stuck to the backing paper, but
not more than the label easily can be pulled away, manually or by
an automatic applicator. Use a Stop Adjust value of around -60 (
≈
5
mm) to obtain that; i.e. after the printing is completed 5 mm less of
paper feed than normal will be performed. However, if you still
want to print from the top of the label, you must compensate by a
Start Adjust value of -115 (
≈
10 mm). Note that the sum of the Start
and Stop Adjust values always is 175 dots (15 mm), which equals
the distance between dot line and tear off edge.
Cut off operation is another case where you have to use Start and
Stop Adjust. The cutting edge of the cutter is situated approximately
35 mm in front of the dot line and 20 mm in front of the tear off edge.
If you do not want to cut the label in two, you must use a Stop Adjust
of 250 dots (
≈
21 mm) to feed out the required extra 20 mm
of paper web after the printing is completed and before the cutter is
activated. Now, this means that you will start the printing well down
the label, unless you compensate with a Start Adjustment of
approximately -425 dots (
≈
35 mm). Note that the sum of the Start
and Stop Adjust values is still 175 dots (15 mm).
A special case is tickets with black marks. It is recommended to
place the black mark adjacent to the perforation or the intended tear
off line. If the black mark is placed further down the web, this must
be compensated for by a negative Stop Adjust setting.
