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

The monitor led is green but it gives white flash and still blank

Check the volatage regulator in the mainboard resolder all you found dried unsolder parts inside mainboard. Voltage test the regulator IC if have a voltage flow 2.5 to 5v DC. check ribbon cable connector from mainboard to controller board if properly connected. In the controller board find the small fuse test it for open.
When you voltage test in the power board
in the primary section of power supply
use hot ground. Do not use the hot ground
when you voltage testing the secondary
power supply, mainboard and controller
because it will cause of damage
semiconductor. For safety use cold ground
for secondary, mainboard and controller

It might be lost electricity. open the printer case, test the output voltage of power supply. also check all the IC in mainboard. May be, the waste ink flow to the power supply.

Display is OUT but everything functions....... what to do?

SYMPTOM: No Display.
COUNTERMEASURE: Re-solder the following components on PCB X34-415:
R43, R44, R46, R47, R48, R49, R50, R51, R55, and R57.

Ok so if you remove the top of the unit and cd player down the right side you see a line of surface resistors that say 2R7 on them, they all need to be resolders to the bord theres 9 total.

RM computer-

be sure you downloaded the graphic driver for your computer. you can find it from the manufacturer website or if you know the model of your mainboard you can also find it from the mainboard manufacturer website. also, try changing your display settings by right click your desktop and choose properties then choose display adjust the screen resolution on higher pixel. but my best guess is you need the graphic driver of your computer.
