Calibrations Status
This page contains the following information:
General Calibrations (performed by Service Engineers).
Media Specific Calibrations (performed by the User).
General Calibrations
LED Gain Offset and Line Sensor to Black relate to the Line Sensor
and these are done when performing the Line Sensor Calibration.
Drop Detector relates to the Drop Detector or Service Station
calibration.
Paper Advance relates to the Service Paper Advance Calibration.
Printhead Alignment relates to the Printhead Alignment which then
changes to ‘pending‘ when a Printhead is replaced and the Printhead
Alignment has not been performed.
When a component is replaced, the corresponding calibration
is NOT automatically set to ‘NOT DONE‘. This is because the
Printer does not know that there is a new part installed.
Media Specific Calibrations
This section shows the following for each type of media:
Color Calibration.
Paper Advance per media type and ‘optimized for‘ Text/drawing and
Graphics.
Information on these 3 Calibrations

text will also be added here:
