Error CE40: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.
PRINTERCAT : (2) Check “Output value display of image quality sensor / Low-density pattern (05-391-0 to 3)” tocheck if the low-density pattern abnormality occurs for each color. The values under 320 for Y, Mand C, and under 220 for K are defined as low-density pattern abnormality.
PRINTERCAT : (3) Check “Output value display of image quality sensor / High-density pattern (05-390-0 to 3)” tocheck if the high-density pattern abnormality occurs for each color and identify the color whichpattern is abnormal. If the value is 630 or above, it is defined as high-density pattern abnormality.
PRINTERCAT : (4) Set the values of “Image quality closed-loop control / Contrast voltage (08-556)” and “Imagequality closed-loop control / Laser power (08-557)” to “0” (Invalid).
PRINTERCAT : (5) Perform “Enforced performing of image quality open-loop control (05-394)”.
PRINTERCAT : (6) Output the image quality control test pattern (04-270) more than one time and check the patch ofthe color identified in step (3) to see if the image is abnormal (Note).
PRINTERCAT : (7) Replace the image quality sensor.
PRINTERCAT : (8) Set the values of “Image quality closed-loop control / Contrast voltage (08-556)” and “Imagequality closed-loop control / Laser power (08-557)” to “1” (Valid).
PRINTERCAT : (9) Perform “Enforced performing of image quality open-loop control (05-394)” and make sure it iscompleted normally. (Error [CE40] does not appear.) Then perform “Automatic gamma adjustment“( Chapter 3.5.1 and 3.6.1).(10) Clear all "Image quality control abnormal detection counter Y to K display/0 clearing (08-573 to576)".
