Run Manual Cal
Run Manual Cal 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 Run Manual Cal, press
↵ when “Run Manual Cal” displays under
the SENSOR SETUP menu. You will then be prompted for the remaining
steps.
Example: “REMOVE MEDIA/Press Enter”
NOTE: When requested to load an item make sure to place the item in a
position where the media sensor can detect the item. For example,
when requested to “LOAD MARK” place the Mark (Black TOF Line) at
the media sensor.
During the last stage of Run Manual Cal, 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.
Run Manual Cal 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.
Run Manual Cal supports label lengths up to 35 inches for Gap or Mark
sensing when Use Label Length is set to Disable.
Pwr Up Action
• Auto-Cal (factory default). 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.
NOTE: If the printer is in Peel mode a calibration will not be done unless
“Cal in Peel Mode” is set to enable.
• Seek TOF . Moves the media to TOF at power up provided that the user
has already calibrated media using gap/mark sensor. A seek to TOF will
not be done if Gap/Mark Sensor is set to Disable or Ticket Save Mode is
set to Enable.
• Disable . No movement at power up.
