Paper Reference 1:
cont. Jam Widthwise A4 size and lengthwise A5 are identical in length, however, the fuser tempera-
Log ture differs. Detecting the fuser temperature depending on this temperature difference
allows detection of paper misfeed due to a wrong paper size.
Reference 2:
The DU cover of the duplex paper conveying section is designed to operate as being
held against the main unit as the paper cassette is installed. (Paper feeding fails when
the paper cassette is not properly installed because of the resultant space between the
DU cover and the main unit.) Therefore, paper jam occurs if the paper cassette is opened
in the middle of duplex printing.
