Control Algorithm
Feeding
When feeding from a paper tray, the drive of the Pick-Up Roller is controlled
by the Solenoid.
The printer feeds the paper from the Manual Feeder according to information
provided by the Manual Feed Sensor, and by driving the Main Motor, insert
the paper in front of the Feed Sensor.
Different types of Jam are provided in the following table:
Jam Errors
Item Description
JAM 0 This is an indication that the leading edge of the paper did not
pass the Feed Sensor.
■ After paper pick, paper does not enter the printer.
■ After paper pick, paper enters the printer, but does not reach
the Feed Sensor in the specified time.
■ If paper has been picked, and the Feed Sensor is not On, the
printer will re-pick. If after re-picking, the Feed Sensor is still
not reported as On, this error will occur.
This is an indication that the leading edge of the paper already
passed the Feed Sensor.
■ Even though paper reaches the Feed Sensor, the Feed Sensor
is not On.
JAM 1 This is an indication that the paper is between the Feed Sensor
and the Exit Sensor.
■ After the leading edge of the paper passes the Feed Sensor,
the trailing edge of the paper cannot pass the Feed Sensor in
the specified time. (The Feed Sensor cannot be Off.)
■ After the leading edge of the paper passes the Feed Sensor,
paper cannot reach the Exit Sensor in the specified time. (The
Exit Sensor cannot be Off.)
JAM 2 After the trailing edge of the paper passes the Feed Sensor,
paper cannot pass the Exit Sensor in the specified time.
DUPLEX JAM 1 After the trailing edge of the paper passes the Exit Sensor, the
leading edge of the paper cannot reach the Regi Sensor in the
specified time.
DUPLEX JAM 0 After the leading edge of the paper passes the Regi Sensor, the
leading edge of the paper cannot reach the Feed Sensor in the
specified time.
