Parameters Used

Garbage, Black Mark and Out Of Paper Detection

Garbage range n40

Printed black mark n39

Valid black mark range (n39 – n40 + 5mm)

5mm Constant

Out of paper

For every step the paper is feed, the black mark sensor is sampled to detect garbage, black marks or out of paper.

When the printer detects blackness is has to check if it is only garbage:

91

If the paper…	Then it is…

gets white again within n40 x 0.1 mm	garbage and the spot should be
	ignored.

is still black after n40 x 0.1 mm	probably a black mark.

gets white within an additional n39-n40 plus 5 mm	a black mark

The 5-mm is a constant added to make sure that noise on the edge not will interfere with the samples. If it at this point still is still black we have detected out of paper.

n37 &

n38

Detection area

n39

10 mm

Be careful about n40 and n39. If n39 – n40 is too small, then the minimum detection area will be too little. This area should not be less than 2 mm.
