SOURCE: Error code C380 paper feed failure

c380 indicates auto-toner error for black developer (K).

Check following:

Is the harness between the LGC board and the developer unit drawer connector open-circuited?
Is any harness inside the developer unit or the auto-toner sensor harness open-circuited?
Is the auto-toner sensor connector or the connector CN341 on the LGC board disconnected?

IF connector no problems, then u probably need to replace the auto toner sensor.

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
