Adjustments and Maintenance

2.0 Introduction
This section details the correct calibrations, hardware adjustments, and maintenance for the printer.
2.1 Media Sensor Calibration
In addition to selecting the Media Sensor type and positioning the Media Sensor, calibration is required to
ensure that each label is detected correctly and reliably. Three calibration methods, described below, are
available.
2.1.1 Quick Calibration
Quick Calibration should be performed during initial printer set-up or after changing the media to fine-tune
the TOF and label values.
 Notes: (1) Quick Calibration is not required for continuous media; however, if UNCALIBRATED is
displayed, use Standard Calibration (see Section 2.1.2) to calibrate the printer.
(2) Media containing large gaps may require a change in the PAPER OUT DISTANCE
setting before Quick Calibration is performed; see MEDIA SETTINGS in the Operator’s
Manual for details.
Use the steps below to calibrate the printer:
1. Ensure that the printer is ON and in an idle state (i.e., not off-line) with media loaded, the media
sensor adjusted, and the sensor type selected. (See the Operator’s Manual for details).
2. Press and hold the FEED Key until one label TOF has been output then release the key and wait for
the printer to process the data. There are two possible outcomes:
If CALIBRATION COMPLETE is displayed, then calibration was successful. (A ‘WARNING LOW
BACKING’ message may appear if using notched stock or media with a transparent liner;
however, the calibration was successful). The printer will advance the media to the next top of
form ready to begin printing; or,
If CANNOT CALIBRATE is displayed, then calibration was unsuccessful. In this case, press and
hold the FEED Key until two successive label TOFs have been output. If, however, CANNOT
CALIBRATE is displayed again, perform the Standard Calibration routine; see Section 2.1.2.

2.1.2 Standard Calibration
Standard Calibration should be performed when ‘CANNOT CALIBRATE’ or ‘UNCALIBRATED’ is
displayed. During this process, the printhead assembly can be raised for visual access. In addition, active
sensor readings can be used to further determine the best position for small, position-critical TOF notches
or marks. Three readings are required:
Empty: A measurement taken with no media over the sensor.
TOF Indicator: A measurement taken with only the media backing, notch, or reflective mark placed
over the sensor.
Paper: A measurement taken with the label (and the liner) placed over the sensor.
Ensure that the ADVANCED MENU (in the SYSTEM SETTINGS menu) has been enabled, and that the
Media SENSOR TYPE (in the MEDIA SETTINGS menu) has been selected. Then, use the steps below
and the displayed prompts to guide you through the procedure:

This is the MEDIA SETTINGS
menu branch.

PERFORM CALIBRATION, and
then press the YES Key to
proceed.

Ensure that no label stock is
installed in the printer then press
the ESC Key.
REMOVE LABEL STOCK
PRESS ESC KEY
yyy
This sets the empty value -
where ‘yyy’ is a numerical
value representing the sensor
reading when no media is
installed.
5
Proceed according to the kind of
media being calibrated:
Die-Cut Media -- Remove at least
six inches (15cm) of the
beginning label material from the
liner, and then install the media.
Adjust the Media Sensor (per the
table below) then press the ESC
Key.
Notched or Reflective Media --
Install media. Adjust the Media
Sensor (per the table below), and
then press the ESC Key.
Continuous Media -- Install
media. Position the Media
Sensor (per the table below).
For die-cut media:
SCAN BACKING
PRESS ESC KEY
yyy
- or, for reflective media:
SCAN MARK
PRESS ESC KEY
yyy
This sets the gap (or mark)
value - where ‘yyy’ is a
numerical value representing
the sensor reading for the
TOF indicator.
Do not position a media
perforation over the sensor
when taking any sensor
reading.
If using media with small
notches or reflective marks,
ensure that the labels exit
straight from the printer.
Do not move the position of
the Media Sensor following
this step.

Position the label material (and
liner, if any) over the sensor
then press the ESC
Key.
SCAN PAPER
PRESS ANY KEY
yyy
This sets the paper value -
where ‘yyy’ is a numerical
value representing the sensor
reading for the media.
If using preprinted media,
ensure that the label area
placed over the sensor is free
of preprinted text, graphics, or
borders.

Observe the display for the
outcome of the calibration then
press the ESC Key.
For die-cut media:
GAP MODE
CALIBRATION COMPLETE
- or, for reflective media:
REFLECTIVE MODE
CALIBRATION COMPLETE
- or, for continuous media:
CONTINUOUS MODE
CALIBRATION COMPLETE
Calibration was successful.
If ‘Warning Low Backing’ is
displayed (a typical message
when calibrating notched
media or die-cut labels on a
transparent liner), calibration
was still successful. For other
possible messages, see Fault
Messages in the Operator’s
Manual.

2.1.3 Advanced Entry Calibration
ADVANCED ENTRY should only be used when the Standard Calibration method has failed (see Section
2.1.2). To facilitate the placement of the media sensor, the printhead assembly can be raised. During this
procedure, sampled readings will be used to manually establish the best gain algorithm for sensing the
media. The steps below will guide you through the procedure:
