SERVICE REQ. 0001001D

􀂆 Error meaning:
CR servo parameter error
􀂆 Explanation
There may be a case where a voltage exceeding the specified value is
about to be applied to the CR Motor. In such a case, this message is
displayed and the printer stops operating.
􀂆 Points to be checked
1. The CR Encoder Sensor and the CR Scale must be free from dust and
dirt or any other foreign matters.
2. Execute encoder checking by the "1.4.6.1 Self Testing Menu (SELF
TESTING)" (p80) in "Maintenance Mode 2".
3. The CR Timing Belt must be free from any defects and the belt must
be in proper tension.
4. The Carriage Unit must slide smoothly, free from undue load.
5. Measure the resistance value of the CR Motor. (17.9 ± 10% [Ω])
If the CR Motor is found in short mode, replace the C511 MAIN Board
at the same time.
6. All the harness must be connected properly and free from short circuit
or broken wire.
􀂆 Remedy
1. Check for dirt, paper dust or damage to the CR Scale
2. Perform the CR Timing Belt Tension Adjustment (p363)
3. Replace the CR Encoder Sensor (p273)
4. Replace the Motor Assy., CR (p264)
5. Replace the C511 MAIN Board (p221)

SERVICE REQ. 00010004

􀂆 Error meaning:
CR Motor Encoder check error
􀂆 Explanation
During initial operation at power on or during CR Motor operation, there
may be a case where the encoder pulse signal is not input at specified
intervals. In such a case, this message is displayed and the printer stops
operating.
􀂆 Cause of trouble
􀂄 Disconnected FFC for the CR Encoder Sensor.
􀂄 Disconnected connector for the CR Motor.
􀂄 Broken wire for the CR Motor Encoder Sensor.
􀂄 Inverted wiring for A and B pulses.
􀂄 Inverted wiring for the CR Motor.
􀂄 CR Motor short
􀂆 Points to be checked
1. CR Scale is disconnected from CR Encoder Sensor.
2. The CR Encoder Sensor and the CR Scale must be free from dust and
dirt or any other foreign matters.
3. Execute encoder checking by the "1.4.6.1 Self Testing Menu (SELF
TESTING)" (p80) in "Maintenance Mode 2".
4. The CR Timing Belt must be free from any defects and the belt must
be in proper tension.
5. The Carriage Unit must slide smoothly, free from undue load.
6. Measure the resistance value of the CR Motor. (17.9 ± 10% [Ω])
7. All the harness must be connected properly and free from short circuit
or broken wire.
􀂆 Remedy
1. Check to see if the CR Scale for detection of the encoder pulse is
removed.
2. Check for dirt, paper dust or damage to the CR Scale.
3. Check if connection of the CR Encoder Sensor connector or Motor
Assy., CR connector.
4. Perform the CR Timing Belt Tension Adjustment (p363)
5. Replace the CR Encoder Sensor (p273)
6. Replace the Motor Assy., CR (p264)
7. Replace the C511 MAIN Board (p221)
