Paper Out Sensor
Selects which type of media sensing, Reflective or Transmissive, will be used
to detect a paper out condition. The printer automatically selects the type of
sensing based on the Gap/Mark sensing selected (see Table 6 on page 138).
NOTE: Whenever you select Transmissive, you must position the upper
media sensor directly over the lower media sensor (see "Positioning
The Media Sensors" on page 66).
The factory default is Reflective.
Manual Calibrate
Manual Calibrate is another method of improving the printer's media sensing
and is only used when Auto Calibrate has failed or the Gap/Mark Threshold or
Paper Out Threshold values derived from Auto Calibrate do not improve the
media sensors' gap or mark sensing capability.
To initiate Manual Calibrate, press ↵ when "Manual Calibrate" displays under
the CALIBRATE CTRL menu. You will then be prompted for the remaining
steps.
Example: "REMOVE RBN&MEDIA/Press Enter" or
"LOAD RBN ONLY/Press Enter" etc.
During the last stage of Manual Calibrate, the printer uses the statically
derived values, advances media, stops at the Top-of-Form position, and
momentarily displays the Sensed Distance. This process takes longer than
Auto Calibrate, and the end result is a change to the Gap/Mark Threshold,
Paper Out Threshold, and Sensed Distance values that the printer will use.
These value changes take effect immediately within the current configuration
menu.
Manual Calibrate is completed successfully when the displayed Sensed
Distance correctly matches that of the installed media. When Gap is selected,
the Sensed Distance should match the length from the trailing edge of one
gap to the trailing edge of the next gap (or one label + one gap). When Mark is
selected, the Sensed Distance should match the length from the leading edge
of one black mark to the leading edge of the next black mark.
Manual Calibrate supports label lengths up to 24 inches.
Pwr Up Action
•
Disable. No movement at power up.
•
Auto-Cal. When the printer is first powered on, it will complete its
initialization and self-tests and then perform an Auto Calibrate. Once the
Auto Calibrate is complete, the printer will momentarily display the
Sensed Distance determined by the Auto Calibrate.
•
Seek TOF. Assumes user has already calibrated media and used gap/
mark sensor. This moves the media to TOF (Top of Form) at power up.
Seek TOF will not be performed if the Gap/Mark Sensor is set to Disable
or if the Ticket Save Mode is set to Enable.
The factory default is Disable.
