Step 3: Using the Option
During operation, labels will be dispensed “on-demand” – that is, subsequent printing will occur only after a
previously printed label has been removed from the printer. As a reminder, “REMOVE LABEL” will be
displayed to prompt you when a label awaits removal. Begin using the option as follows:
A) Load media and close the Access Cover (see the Operator’s Manual for details).
B) Plug the power cord into the AC Receptacle and turn ‘On’ the Power Switch.
C) Ensure that READY is displayed on the Front Panel then press the FEED Key, and proceed
according to your observations:
 If REMOVE LABEL is displayed on the Front Panel, this completes the installation; or,
 If REMOVE LABEL is not displayed on the Front Panel, proceed to Step 4: “Configuring the
Printer.”

 Notes: (1) The operation of the Present Sensor can also be controlled by host software commands,
so ensure that your labeling program is properly configured for use when sending label
formats to the printer.
(2) If the Present Sensor is removed with power applied, the printer will behave as if a label
awaits removal; to restore normal operation, cycle power to the printer.
