Hi
I hope that this will help you

[CE40] Image quality control test pattern abnormality

(1) Use "Image quality control abnormal detection counter Y to K display/0 clearing (08-573 to 576)"to check the abnormal occurring condition for each color.

(2) Check "Output value display of image quality sensor / Low-density pattern (05-391-0 to 3)" to

check if the low-density pattern abnormality occurs for each color. The values under 320 for Y, M

and C, and under 220 for K are defined as low-density pattern abnormality.

(3) Check "Output value display of image quality sensor / High-density pattern (05-390-0 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 630 or above, it is defined as high-density pattern abnormality.

(4) Set the values of "Image quality closed-loop control / Contrast voltage (08-556)" and "Image

quality closed-loop control / Laser power (08-557)" to "0" (Invalid).

(5) Perform "Enforced performing of image quality open-loop control (05-394)".

(6) Output the image quality control test pattern (04-270) more than one time and check the patch of the color identified in step (3) to see if the image is abnormal.

(7) Replace the image quality sensor.

(8) Set the values of "Image quality closed-loop control / Contrast voltage (08-556)" and "Image

quality closed-loop control / Laser power (08-557)" to "1" (Valid).

(9) Perform "Enforced performing of image quality open-loop control (05-394)" and make sure it is

completed normally. (Error [CE40] does not appear.)

(10) Clear all "Image quality control abnormal detection counter Y to K display/0 clearing (08-573 to 576).

Good Luck

Regards

CE40:Image quality control test pattern abnormality: The test pattern.

Switch off at the right hand side of the machine, wait 10 seconds, then turn it on back again. I should clear.

I think it is caused by condensation, it can also be transfer belt failure, or paper rubbing against the transfer belt
