Service Calibrations 4-25
Service Calibrations This section shows you how to perform the following service
calibrations. For best results, you should perform all three cali-
brations in this order:
Head Height
Media Thickness Sensor
Service Station
Calibrating the
Head Height
1. Remove any media that may be loaded across the platen.
2. From the Front Page, select Calibration > Service Calibra-
tions > Head Height Calibration.
The printer’s menu will prompt you to make sure the media
is unloaded, then it raises the rail. Next, the carriage moves
to the middle of the platen.
3. Insert the head-height gauge beneath the service (left) end
of the carriage as shown below.
Ensure that the gauge is on the edge of the carriage and not
the lamps.The proper location of the gauge is at the edge of
the carriage pen plate. It should not be under the lamps or
under a printhead (which would damage the printhead).
