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 driveroller 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
The line sensor on the cartridge carriage is also used to
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
Media Margins
Hard3clip side margins provide protection against writing on the drive roller due to media expansion/contraction or skew. Top and bottom margins are set according to the physical spacing between the pinch3wheels, overdrive and writing head. (Specifications ' chapter 1.)
Media Sizes
You can use a wide variety of media sizes, due to the
DContinuous roller
DSpacing of the pinch3wheels and star3wheels
DEdge3detection capability
