Media-length detection
The DC controller detects the length of paper to prevent 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 the TOP sensor until the trailing edge
passes through, and then determines the paper size.
The DC controller determines a media-size mismatch and notifies the formatter when the detected paper
size meets the following conditions:
The detected paper size is different from the size designated by the formatter.
