Theory of Operation
Engine F/W
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.
The jam errors are described in the following table:
Jam Errors
Item Description
JAM 0 The leading edge of the paper did not pass the Feed Sensor.
■ After paper has been picked up, paper did not enter the
printer.
■ After paper has been picked up, paper enters the printer, but
did not reach the Feed Sensor in the specified time.
■ After paper has been picked up, 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 occurs.
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 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 Duplex Jam 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.
