The paper-near-end sensor alerts the system when a couple of meters of paper remain on the roll. The purpose of this sensor is to get an early alert so that you can replace the paper roll in time in remotely located kiosks.

The weekend sensor should alert when the remaining paper does not last over a weekend. A reason to use this sensor is that it is more expensive to get a service technician out on a weekend or holiday than it is to replace the roll before it is totally empty.

The Zebra 150 mm paper roll holders are equipped with paper-near-end sensor only, while the 250 mm roll holders have both paper-near-end and weekend sensors.

When installing the Zebra roll holder just connect the cable from the roll holder to connector J1 at the back of the printer. See Figure 1, Printer Exterior, Rear View , on page 9.

If you use custom designed roll holders, connect the sensors according to Figure 8, Paper- near-end Sensor Connection, on page 22.
