Confidential 4.2.3 Digital Output (DO) Test
This function checks whether the Digital Output (DO) components (Motor, Clutch and Solenoid)
operate.
When the interlock is opened while the Motor Test is performed, each component ends to operate.
In this Test Mode, each DO component can be turned individually. Therefore it allows
the CE to check a components operation from outside, and judge whether the component
is normal or not.
When all the diag. functions are stopped, all the DO components can be turned off.
DO test can make each of the DO components operate simultaneously.
When a paper jam or PQ problem is occurred, or an error message or code is displayed, this test
enables to look for the broken or damaged parts.
Test result: NG (Go to each FIP or replace the parts.)
OK (Turn off/on the main power.)
4.2.4 Executing Motor Test
1) Power off the printer.
2) Power on the printer while pressing S and T keys.
3) Release the fingers from these keys when the CE Mode and Password is displayed.
4) Press T key twice and press OK key.
5) The CE Mode and ESS Diag are displayed. (Entered the Diag. mode.)
6) Press T to select IOT Diag, and then press OK key.
7) Press T key to select Digital Output, and then press OK key.
8) Press S or T key to select the test item.

Confidential - About Clutch
The electromagnetic clutch in the printer controls the rotation of the roller by allowing or interrupting the 
torque transmission from the motor to the roller.
By the passage of electric current through the coil inside the case, the electromagnetic clutch becomes 
an electromagnet, and attracts the armature and gear to the rotating rotor, thereby rotating the gear.
Upon the loss of power to the coil, electromagnetic force is lost and the armature comes off the rotor, 
and the gear comes to rest.
The clutch makes so soft noises that you must be close the component to audibly confirm the operation 
of the component.

Confidential - About Solenoid
The solenoid in the printer opens or closes the shutter, or controls the position of the gear for transfer-
ring the torque of the motor to the roller.
By the passage of electric current through the coil inside the case, the solenoid becomes an electro-
magnet and attracts the plunger.
Upon the loss of power to the coil, electromagnetic force is lost, and the plunger returns to its original 
position by spring action, thereby allowing the shutter to operate or the gear to move to the predefined 
position.
Unlike a clutch, a solenoid generates a loud operation noise.
