5.4.2 Check Media Skew
This procedure will feed a specific amount of paper (a single pass band feed) and the sensors will read the
position of the edge of the media before and after feeding and check for any discrepancy. If no media is
loaded when this item is selected, you will be asked to load the media. After media initialization, when the
amount of media feed is entered, the edge sensors will detect the left and right edges of the media and
media feed will begin. After feeding the specified amount, the edge sensors will again detect the left and right
edges of the media and any difference from the readings before media was fed will be checked and
displayed. A media recognition error before and after feeding, or detection by the rear sensor of no paper
during feeding, will cause a media error to be displayed and this procedure may be terminated by pressing
any key. To terminate the procedure when processing is not in progress, press [Back] on the panel or [ESC]
on the terminal.
Caution:
Make sure media is properly loaded.
The first time this adjustment is made, the reference position for media skew will be
determined by detecting the right edge (origin side). If the adjustment is made with a bad
media loading position, that position will become the reference position and “Media skew
error” will occur frequently.
Press [ENTER] to move to “Adjustment: Rank Input” or [Back] to move to “AJST: ChkPaperMov”. Other panel keys are
ignored during processing.
