CHAPTER 2 OPERATIONS
Both separation sensor and skew sensor are used to check for skew movement. The two sensors
are arranged in a row in front-to-rear direction, and the machine checks for skew movement based on
a discrepancy occurring when an original moves past these two sensors. The machine will identify a
skew movement when the discrepancy is 10 mm or more, stopping its operation to protect the origi-
nal and causing the copier to indicate the Jam message.
