CE40: Image quality control test pattern abnormality:
The test pattern is not formed normally. If you switch off at the right hand side of the machine, wait 10 secs then back on again, It should clear. I think it is caused by condensation.
It can also be transfer belt failure, or paper rubbing against the transfer belt. It could be because the Developer Unit failed to Pass the Close Looping Check by the machine every time it boots.... check for fault from 08-824 if the value of any color is " 1 " means abnormal occur.... check for foreign matters on the dev tank...the simplest way is clean all 3 tanks...then reset it back to "0" then do a 05-200 and 05-396-4-Fax-1624-Set
95% solved the case

Hi [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
I hope that this will help you
