Image Sensor Height Calibration:
this finds the correct focus height for the image
sensor. A fine-line grid pattern is printed. The LCD then displays a real-time im-
age of the sensor’s view of this grid. The technician uses buttons on the control
panel to raise and lower the rail in fine increments until the image in the LCD
shows crisp dots.
The images above show the control panel display during this calibration. The im-
age on the left is out of focus at the start of the procedure; on the right, in focus
just prior to accepting the calibration setting.
Image Sensor Position Calibration:
the exact position of the image sensor as-
sembly relative to printhead no. 1 varies slightly from engine to engine. This
option runs a routine that allows the printer to determine the exact relationship
so that printing occurs in the right place relative to the measured locations of the
media edges. This is a concern primarily in edge-to-edge printing only.
Media Sensor Position Calibration: Prints a pattern that allows for calibrating the
position of the media sensor.
Reset Motor Positions
Allows the operator to reset to their home positions each of the following:
Carriage
Rail
Service Station
Shutters
Access Printheads
Moves the carriage to the center of the platen.
Measure Media Width
Commands the carriage to measure the width of the media without going through the
complete Load Media process.
