< In the carriage over the maintenance unit? >
[Move carriage to maintenance unit]
[x = reflection sensor reading of position with no media]
[Move carriage to a position where the reflection sensor comes over the media a = reflection sensor reading]
[Move 5 mm towards A, b = reflection sensor reading]
[Move 5 mm towards B, c = reflection sensor reading]
[Media edge (z) = (x + (a + b + c) / 3) / 2]
[Move carriage slowly towards B to a position where reflective sensor value is z]
[Move carriage to a position where the reflective sensor comes over the media]
[Move carriage slowly towards A to a position where reflective sensor value is z]
[Media width = e2 - e1 : Move carriage to e1 position]
< Moved 200 mm? >
[Media detection error]
< Is reflective sensor value z ? >
< Moved 50 mm? >
< Is reflective sensor value z ? >
