1-2. I/O CHECK

(1) Check Procedure

To allow sensors to be check ed for operation easily and safel y, data applied to the IC on the board can be checked on the panel with the copier in the standby state (including a misfeed, malfunction, and closure failure condition).

Example

When a paper misfeed occurs in the paper take-up section of the copier, the 2nd Drawer Paper Take-Up Sensor is considered to be responsible for it.

1. Remove the sheet of paper misfeed.

2. From the I/O Check List that follows, check the panel display of the 2nd Drawer Paper

Take-Up Sensor. For the 2nd Drawer Paper Take-Up Sensor, you check the data of “Take- Up” of “2nd Drawer.”

3. Call the Tech. Rep. mode to the screen.

→

4. Select “State Confirm”

Up” under “2nd Drawer.” For “Take-U p” under “2nd Drawer,” select “1” on the left-hand side of the screen.

5. Check that the data for “Take-Up ” under “2nd Drawer” is “0” (sensor blocked).

6. Move the actuator to unblock the 2nd Drawer Paper Take-Up Sensor.

7. Check that the data for “Take-Up ” under “2nd Drawer” changes from “0” to “1” on the

screen.

8. If the input data is “0,” change the sensor.

“I/O Check” and then select the screen that contains “Take-

2. PAPER MISFEED

2-1. Initial Check Items

• When a paper misfeed occurs, first make checks of the following initial check items.

Check Item Action

Does paper meet product specifications? Change paper. Is paper curled, wavy, or damp. Is a foreign object present along the paper path, or is

the paper path deformed or worn? Are the Paper Separator Fingers dirty, deformed, or

worn? Are rolls/rollers dirty, deformed, or worn? Clean or change the defective roll/roller. Are the Edge Guide and Trailing Edge Stop at correct

position to accommodate paper? Are actuators found operational as checked for correct

operation?

Change paper. Instruct user in correct paper storage.

Clean or change the paper path. Clean or change the defective Paper Sepa-

rator Fi nger.

Set as necessary.

Correct or change the defective actuator.

AIDC Sensor 1 (UN20) AIDC Sensor 2 (UN21)

reading of a point of a bare surface on the Transfer Belt is 4.5 V or more during an adjustment of the AIDC Sensor.

• The output from the photoreceiver of the AIDC Sensor that takes a reading of a point in a toner pattern on the Transfer Belt is 1.0 V or less after the adjustment has been completed.

Relevant Electrical Parts

IO Board (PWB-IO) Image Transfer Belt Unit

Step Action

1 Wipe clean the surface of the Transfer Belt with a soft cloth, if it is dirty. 2 Change the Image Transfer Belt Unit if the Transfer Belt is damaged. 3 Reinstall or reconnect UN20 or UN21 if it is installed or connected improperly. 4 Clean UN20 or UN21 if it is dirty.

Open and close the Left Door, run an image stabilization sequence, and

select “State Confirm” -> “Level History 1” to check the AIDC value. If the value is 1.0 V or less, change UN20 or UN21.
