Paper edge detection

Sets the duration the light is emitted from the CIS (contact image sensor) to detect the paper edge for color media.

Use this if excessive (JAM97/JAM98) skew/shifting occurs frequently. When printing on highly reflective paper such as thick color paper, a (JAM97/JAM98) paper jam may be erroneously detected. In such a situation, it is necessary to make adjustments such as increasing luminance.

Also, if CIS luminance is high, paper dust and stains may accumulate in the machine, and this may cause erroneous (JAM97/JAM98) jam detection. When printing on plain and thin color paper, it may be effective to adjust the luminance to standard value "3".
