Segmented Printing - SATO GY412 Operator's Manual

8.7 SEGMENTED PRINTING

The GY412 printer has two thermal heads which enable double sided printing. If the line with high print ratio is
used at the same time, the electric current will exceed its specified range and this may result in power supply
failure.
Since the segmented printing solves the above problem, the peak current will be within the specified power
supply range.
8.7.1 Segmented Printing Motion
The printer analyzes the print data. If the line with high print ratio is within the data and if it exceeds the
specified print ratio, the following motions will occur.
1.
If there is a condition for segmented printing within the item, the print speed will be forcibly changed to 5
inch/sec for executing the segmented printing. When the print speed is less than or equal to 5 inch/sec, the
segmented printing will occur without changing the print speed. In that case, the segmented printing will be
effective to the end of corresponding item.
2.
If there are conditions for segmented printing within the target item and its consecutive item, the
segmented printing will be valid for the consecutive item.
8.7.2 Segmented Printing Conditions
When the printer analyzes the print data in the conditions below, the segmented printing will be executed.
1.
Conditions within the item
The maximum value of pitch offset for upper and lower surfaces is ±7.5mm. If executing the pitch offset, the
base position for print for upper and lower surfaces will be the maximum range of ±15.0mm. The print ratio will
be calculated based on the base position for print (lower surface) ±15.0mm. When the total print ratio (upper
and lower surfaces) becomes 132% or more, the segmented printing will occur.
