2. TROUBLESHOOTING PROCEDURES

2.1 Precautions prior to repair

(1) Conﬁrm the basic check items indicated in the User's Manual.

(2) Through hearing from the user, obtain information, as far in detail as possible, on the situation concerning the fault.

(3) Inspect the printer in a condition close to the actual situation in which the fault occurred.

2.2 Items to be checked prior to taking action on abnormal images

(1) Check to see if the printer is operated in an adequate environment.

(2) Check to see if the consumables (toner, drum cartridges) are replaced properly.

(3) Check to see if the right paper is used. See the paper speciﬁcations.

Clearing Paper Jams

This section explains how to clear paper jams.

Reference! • For details on the location of each component of the machine, refer to

"Swich scan test" and "Motor clutch test".

Checking Error Messages

When a paper jam occurs, the [Paper jam] or [Document jam] message appears on the display screen and the <STATUS> key on the operator panel blinks. The error code and description differ according to where the paper jam occurs.

Possible to get burned.

Since the fuser unit right is extremely hot, perform the operation with care.

Note! • The image drum (the green tube) is very delicate. Handle it carefully.

• Do not expose the image drum to direct sunlight or very bright interior light (approximately more than 1500 lux). Even under the normal interior light, do not leave it for more than 5 minutes.

Replace the toner sensor board or the FFC between the toner sensor board and the CU/PU board.

Note! Toner sensor operation check method using the SWITCH SCAN function of

the self-diagnostic mode.

(1) How to check operation of the toner sensor at the printer side.

1. Status change of the toner sensor can be checked from the control panel using the self-diagnostic mode. First, switch the display to the control panel display. For the method of switching the display to the control panel display, refer to section 3.4.3 Switch Scan Test

2. Remove the ID unit and the toner cartridge (TC) from a printer. There is a window inside a printer opposing the ID side when viewed from the front of a printer. The toner sensor is located inside the window.

3. Place a white paper 3 mm away from the sensor window. The white paper should be placed in the manner of opposing the toner sensor.

4. When light is reﬂected by a white paper so that incident light falls on the toner sensor, the control panel display shows "L". When the paper is moved so that any light is not reﬂected by the paper so that the incident light does not reach the toner sensor, "H" is displayed on the control panel.

5. If the control panel display toggles between "H" <-> "L" as a paper is ﬂipped

in front of the toner sensor, it indicates that the toner sensor and the related

system of the printer are working normally.

Action to be taken at NG

• Clean surface of the toner sensor to remove the stains due to residual toner and paper dust.

• Check the connection condition of the FFC cable between the CU/PU board and the toner sensor board (TSA).

• Perform the operation check again. If the situation has not bee improved and

remains unchanged, replace the CU/PU board or the toner sensor board (TSA).

(2)

How to check operation of the toner sensor at the toner cartridge (TC) side

1. To the position where the toner sensor is conﬁrmed to be operating normally in the printer itself by the above paragraph (1), install the TC and the ID unit to check operations by observing display on the control panel.

2. If the ID unit works normally, the display on the control panel will toggle between "H" <-> "L" in synchronism with movement of the silver reﬂector plate that is located on the side of the ID.

Action to be taken at NG

• Check operation condition of the respective ID motors by using the Motor & Clutch Test of the self-diagnostic mode.

• Clean surface of the silver reﬂector plate on the side of ID to remove stains. (Stain due to toner or paper dust)

• Replace the TC of different color and the ID unit as a pair.

If a satisfactory operation is attained by using the a pair of TC of different color

and the ID unit, replace the TC or replace the ID unit.

Is the environment condition changed sharply from a low temperature environment to a high environment condition within a short time? (Example is such a case that a printer is moved from storage condition of a cold area in winter to an ofﬁce environment.)

Actions to be taken

at NG

Leave a printer for around one hour in the new environment to get used to the new environment. After that, turn on the power again. Before turn on the power, touch the metal panel of the controller panel and the metal plate inside a printer to feel temperature increase inside a printer with human hands. After conﬁrmation that the printer temperature has increased close to the room temperature, turn on the power again.
