# Verification Items list

Automatically checks the sensors/motors internal state together with the initial operation and displays the results for the following items:

• Motor runaway
• Connection state of consumables
• Error/jam condition
• Main Unit Sensors/Encoder
• Cassette (Paper Detection Sensor)
• Rear ASF (Paper Detection Sensor)

1. Visually check that the CR action is smooth.
2. Check that the CR motor sound is not abnormal.

Drives the PF motor for approximately 2 seconds to perform a PF motor failure check.

Inspection of the SMAP phase sensor is performed automatically while the PF motor is being driven.

• PF Motor
  Check that the PF motor sound is not abnormal.
• SMAP Phase Sensor
  The inspection result is displayed on the screen after the check finishes.

Visually check that the CR unit and CR shaft are operating as follows.

1. Lift the CR shaft from the PG1 state (PG is at narrowest) to the PG7 state (PG is at widest) and then set it to the release state on the paper guides.

2. Cancel the release state on the paper guides and lower the CR shaft from PG7 to PG1.

• Lift Motor
  Check that the lift motor sound is not abnormal.
• Lift phase sensor
  Check that the display changes according to the inserted/pulled out state of the paper cassette.
  -Paper cassette inserted state
  The “Pull_Out_The Cassette” message appears on the panel LCD.
  
  -Paper cassette pulled out state
  The lift motor operation starts.

Check that there are no abnormalities in the operating sound.
1. Check the operation of the rear ASF solenoid visually and by its sound.
2. Check that the LD roller rotates.
After the LD roller rotates, check from the sound that the motor drive one way clutch is idling due to the one way clutch.

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”.

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.

Supported paper sizes :
A4 / Letter

Judge in the order given below.

1. Check the output values of the temperature and humidity sensors.
   <Error judgment guide>

• • • Broken wire : 0°C or lower
    • Short : 60°C or higher

1. Touch the temperature and humidity sensors with a hand and check the change of the output values.

Check the ink end sensor state with ink present.

Check that the sensor state on the panel LCD changes as a result of moving the ink end sensor lever.

Check the state of the ink leak sensor.
