Detecting the Media Edges

Line Sensor

The plotter detects the left and right media edges using the line sensor located on the carriage. The sensor is composed of

DRed LED

DTwo lenses (caution required when handling)

DCollector plate

Operation

1The sensor finds the left media edge when it detects the light from the red LED reflected off the media surface. The black surface of the drive roller absorbs the light.

Excessive ink deposits on the drive￿roller can fool the sensor by reflecting the light.

2The sensor goes on to find the right media edge.

3The media is advanced and the sensor checks for media skew (crooked loading).

Other Functions

DDetect and measure lines drawn on media when performing cartridge alignment

DDetect and measure lines drawn on media when performing accuracy calibration

DScan the setup sheet
