Code: CE40
Description: Image quality control test pattern abnormality: The test pattern is not formed normally
Causes:
Remedy: 1 Use “Image quality control abnormal detection counter Y to K display/0 clearing (08- 2528 to 2531)” to check the abnormal occurring condition for each color. 2 Check “Output value display of image quality sensor / High-density pattern (05- 2731-0 to 3)” to check if the high-density pattern abnormality occurs for each color and identify the color which pattern is abnormal. If the value is 628 or above, it is defined as high-density pattern abnormality. Under 628 (Y, M, C and K) 3 628 or above (Y, M, C and K) High-density pattern abnormality Check if the laser shutter is working properly. <Procedure> 1. Take off the process unit so that the laser shutter can be easily seen. Clean around the laser shutter if the developer has been spilled over. 2. While pressing the digital keys [0] and [3] simultaneously, turn the power ON. 3. Key in “201”. 4. Press the [START] button and check if the shutter is opened and then closed (reciprocating 1cycle). Check if the developer unit has been installed properly. 1. Visually check the installation status of the developer unit, and correct it if there is any abnormality. To (8) (If you have already performed this checking cycle once, proceed to step (3).) 3 Set the values of “Image quality closed-loop control / Contrast voltage (08-2486)” and “Drum surface potential sensor control setting (08- 2561)” to “0” (Invalid). 4 Perform “Enforced performing of image quality open-loop control (05- 2740)”. 5 Output the image quality control test pattern (04-270) more than one time and the list print ([9][START]) in the adjustment mode (05), and check the patch of the color identified in step (1) to see if the image is abnormal. Normal 6 Abnorm al Abnormal image: Blank print, Solid print, White banding, Color banding, White spots, Poor transfer, Uneven image density, Faded image (low density), Uneven light distribution, Blotched image. Blank print: including when one of the YMCK colors is not printed. ‚ Correct the abnormal image. Proceed to step (7). 6 Replace the image quality sensor or LGC board. 7 Set the values of “Image quality closed-loop control / Contrast voltage (08-2486)” and “Image quality closedloop control / Laser power (08-2561)” to “1” (Valid). 8 Perform “Image quality closed-loop control (05- 2742)” and make sure it is completed normally. (Error [CE40] does not appear.) Then perform “Automatic gamma adjustment”. Normal 9 When an error occurs Check and correct it accordingly. 9 Clear all “Image quality control abnormal detection counter Y to K display/0 clearing (08-2528 to 2531)”. 10 Check if any of the springs for supplying power to the transfer belt unit is deformed. Replace the spring if it is deformed.

Set both values of the codes 08-2600 and 08-8103 to 0. 2. Print the test chart 04-270 with A3/LD for more than 2 pages. Then perform list printing ([9]+[START]) to check if no abnormality is found in the image density. If any abnormality is found, correct it referring to “25.5 Troubleshooting for the Image” 3. .Check if the process unit (EPU tray) and the developer unit are installed properly. 4. Check if any toner or developer material is spilt around the laser shutter. Clean if so. 5. Check the center position adjustment for each drawer is within the range preset at the shipment (rear side: 0-3 mm). "[B] Adjustment of the gear holder" 6. Adjust the image dimension with A3/LD. "[A] Reproduction ratio of primary scanning direction (Image clock fine adjustment (Printer))" "[B] Primary scanning data laser writing start position (Laser writing start position (Printer))" 7. Return both values of the codes 08-2600 and 08-8103 to 1. Then proceed to step 3. If it is the second time, proceed to step 4. 2 628 or above (Y, M, C and K) 2 2.Check each value of the subcodes 0 (Y), 3 (M), 6 (C) and 9 (K) of the code 05- 2800. 180 or above (Y, M, C, K all) 3 Under 180 (Y, M, C, K each) (Low density pattern abnormality) <Procedure> 1. Set both values of the codes 08-2600 and 08-8103 to 0. 2. Print the test chart 04-270 with A3/LD for more than 2 pages. Then perform list printing ([9]+[START]) to check that no abnormality is found in the image density. If any abnormality is found, correct it referring to “"8.5 Troubleshooting for the Image" 3. Return both values of the codes 08-2600 and 08-8103 to 1. Then proceed to step 3. If it is the second time, proceed to step 4. 3 Perform the automatic gamma adjustment. If the adjustment is normally finished, this is the end of the procedure. If the error CE41 still occurs, repeat the procedure from step 1. 4 4.Check if the harness between the connector CN423 on the IMG board and the connector CN319 on the LGC board is disconnected or open circuited. Correct if so. 5 5.Check if the harness between the connector CN424 on the IMG board and the connector CN320 on the LGC board is disconnected or open circuited. Correct if so. 6 6.Check if the conductor patterns on the IMG board and the LGC board are short circuited or open circuited. 7 7.If no abnormality is found in steps 4 to 6 above, replace the IMG board. 8 8.Perform automatic gamma adjustment. If the adjustment is normally finished, this is the end of the procedure. If the error CE41 still occurs, proceed to step 9. 9 9.Reinstall the removed IMG board and then replace the LGC board. Perform automatic gamma adjustment after the board is replaced.
