A.4 Setting up Product Sensors
The Linx 4900 printer uses product sensors to detect the presence of the
product to be printed on. There are variations in the way the printer
interprets a trigger signal. However, it usually prints a message in response
to such a signal from the product sensor.
Figure A-3 Setting up the Product Sensor
Typically, the product sensor is mounted upstream of the printhead, and the
distance between printhead and product sensor would be less than one
message spacing.
A delay between the triggering product sensor and the start of printing is
set through the Print Delay option in the user interface. This allows direct
setting of the print position.
For information about setting the print delay, see ‘To Set the Print Delay’
on page 98.
