Media-Length Detection - HP LaserJet Enterprise 700 M712 series Handbuch Zur Fehlerbehebung

Media-length detection

The DC controller detects the length of paper to prevent the toner stain on the transfer roller and also to
minimize jam occurrences in the duplexer. The DC controller measures the length of paper by
monitoring the time from when the leading edge of paper reaches at the TOP sensor until when the
trailing edge passes through and determines the paper size.
The DC controller determines a media-size mismatch and notifies the formatter when the detected paper
size is under the following conditions:
The detected paper size is different from the size designated by the formatter.
●
The detected paper size is different from the size detected by the cassette media size switch.
