(03-125: Sensor shutter is opened)(13) Key in “126”, then press the [START] button. (03-126: Image position aligning sensor / LED ON)(14) Press the [START] button.(15) Check how items [G] and [H] are displayed while [7] is pressed.(16) Compare them with the statues of [G] and [H] displayed in step 10.(17) Press the [CLEAR] button.(18) Key in “176”, then press the [START] button. (03-176: Image position aligning sensor / LED OFF)(19) Key in “175”, then press the [START] button. (03-175: Sensor shutter closed)(20) Turn the power OFF.(21) If the image position aligning sensors on both sides are operating normally, proceed to step (23).In other cases, proceed to step (22).(22) Check the following items if the image position aligning sensors are not operating normally:Both [G] and [H] are changed - The image position aligning sensors on bothsides are operating normally.[G] remains same - The image position aligning sensor on the rearside is not operating normally.[H] remains same - The image position aligning sensor on the frontside is not operating normally.Both [G] and [H] remain same - The image position aligning sensors on bothsides are not operating normally.Is the connector CN337 on the LGC board disconnected?Is the connector of the image position aligning sensor disconnected?Is the harness between the LGC board and the image position aligning sensor broken?Is the light emitting or receiving area of the image position aligning sensor stained with toner?Are the sensor shutter and the image quality sensor opening or closing normally? Or are theydamaged?Is the light emitting area of the image position aligning sensor emitting LEDs?||||||||||||||< Checking procedure for the sensor shutter opening/closing status >1. Take off the transfer belt unit so that the sensor unit can be seen.2. Turn the power ON while [0] and [3] are pressed simultaneously.3. The shutter should be opened when “125” is keyed in. It should beclosed when “175” is keyed in.< Checking procedure for the LED emission of the image position aligningsensor >1. Key in “125” to open the sensor shutter.2. The light emitting area of the sensor should emit LEDs when “126” iskeyed in.
