3-3. Types of Misfeed Detection and Detection Timings
• The following lists the types of misfeed detection and detection timings for different mis-
feed locations.
• The symbol “L” (for the leading edge) and “T” (for the trailing edge) given in ( ) indicate
the particular edge of the paper detected by the sensor.
NOTE
For the types of misfeed detection and detection timings of options, see the relevant option
service manual.
