Overall A01 Auto Check

Automatically checks the motor/sensor state together with the initial operation and displays the check results of the items given below.

  • Motors runaway
  • Installation state of consumables and other parts
  • Error state/Paper jam state
  • Main unit sensors/encoders
  • Cassette (Paper Detection Sensor)
  • Rear ASF (Paper Detection Sensor)
 The check results are displayed on the panel LCD. Set the one paper to the Rear ASF and each paper cassette.
Output system








 A10 CR motor Moves the CR unit back and forth to perform a CR motor failure check. Check that the CR motor sound is not abnormal. ---
A11 PF Motor Drives the PF motor for approximately 2 seconds to perform a PF motor failure check. Check that the PF motor sound is not abnormal. ---
A13 ASF Motor Drives each ASF motor for approximately 2 to 3 seconds to perform an ASF motor failure check.

 Check that the ASF motor sound is not abnormal.

 ---
A14 ASF Motor (C2)
A15 ASF Motor (C3)
A18 Lift Motor/Sensor (C2) Drives the lift motor for two to three seconds and checks whether the motor works normal and whether the sensor detects the statuses normally. Check that the lift motor sound is not abnormal and the sensor error is not displayed. Remove the cassette
A19 Lift Motor/Sensor (C3)
A21 Supply Pump Motor Drives the decompression motor and checks whether the motor works normally. Check that the Decompression Motor sound is not abnormal. ---
A23 IS Motor Drives the IS motor CW/CCW, and open/close the cap to perform an IS motor failure check. Check that the CR unit moves up/down by the cap up/down operation of driving the IS motor. Open the ADF/SCN Unit or the Printer Cover beforehand.
A31 Rear ASF Solenoid After operating the Rear ASF solenoid, rotate the LD Roller more than once to perform the rear ASF solenoid failure check.

Check that the Rear ASF solenoid sound is not abnormal.
After operating the Rear ASF solenoid, the LD roller rotates. After the LD roller rotated once, check the LD roller does not rotate regardless of motor sound.

Input system













 A40 ALL Sensor Check Displays the state of sensors related to main unit cassette and optional cassette in real time.

Manually switch the target sensor ON/OFF and check that the sensor state displayed on the panel LCD changes.
Regarding the detail of All sensor check,refer to “All Sensor Check Items (All Sensor Check Items)”.

 Since various sensors are mounted, the results are divided in some pages.
A41 Simplex-Cassette 1

Perform paper feeding/ejecting of single side printing from each cassette to check the state of all the cassette related sensors and sensors in the paper feed path.




 The check results are displayed on the panel LCD.





 ---
A42 Simplex-Cassette 2
A43 Simplex-Cassette 3
A45 Simplex-Rear ASF Feed paper from the Rear ASF to check the state of sensors in the paper feed path.
A46 Duplex-Cassette 1 Perform paper feeding/ejecting of double side printing from each cassette to check the state of all the cassette related sensors and sensors in the paper feed path.
A47 Duplex-Cassette 2
A48 Duplex-Cassette 3
A50 Sensor Check - Cassette 1 Perform failure check for each sensor related to each paper feed path.


 Check the state of each sensor changes by installing/removing the cassette and by paper set condition.

---
A51 Sensor Check - Cassette 2
A52 Sensor Check - Cassette 3
A54 Sensor Check - Rear ASF
A57 Temperature and Humidity Sensor Measure the current temperature and humidity, then check that the temperature and humidity sensors are operating normally.

Judge in the order given below.

  1. Check the output values of the temperature and humidity sensors.
    Error judgment guide
      • Disconnection: 0 degrees C or below
      • Short-circuiting: 60 degrees C or above
  1. Touch the temperature and humidity sensors with a hand and check the change of the output values.
 ---
A58 Ink End Sensor

Check the ink end sensor state by comparing the actual remaining ink amount and detection state of the ink end sensor.

Check that the state of the ink end sensor matches the printer state with ink present.

 ---
A59 Ink Leak Sensor

Check the ink leak sensor state with ink present.

 The check results are displayed on the panel LCD. ---
Auxiliary functions A02 CR Unlock Power OFF Turns off the power from the CR unlock state. --- ---
