IMPORTANT: Two options within the Media/Sensor tab can force Auto Calibration:
(1) Power-Up Action = Auto Calibrate
(2) Head Auto Cal = Enable
When option (1) is set, the Auto Calibration procedure happens immediately upon power-up.
When option (2) is set, Auto Calibration happens after the printhead is properly latched and
the Feed key is pressed.
Manual Setup
Manual Calibration is for advanced users only with special
media. The operation calibrates the sensors only. When the
Sensor Calibration window opens
, the values for “Sensor
Intensity”, “Reading Intensity”, and “Threshold Value” are set to
their current va
lues in the printer. The “Current Reading” field is
a read-only field monitored by the printer for comparison with
the set “Reading Intensity” value.
Defaults and explanations for these fields are shown in the table
below with processes for each Media type.
