E-451c CE40 code.

[randy_ful]

I'm new to the site, and I have an e-studio 451c I have been working on for about a week, and It comes up with a CE40 code when it starts up after going into the automatic calibration, but that is the ONLY time it will show a CE40. I got this error BTW, after replacing the transferbelt and developing material. I have gone through the handbook and followed the troubleshooting material, to no avail.

any help would be awesome.

You need new firmware : v33L

[randy_ful]

its got t410sy0u340

[Paper_path]

Take any finisher/bridge unit off the machine, and run the machine without the center cover on it (the one in the belly of the machine.) Watch the pattern on the belt to see what color is light or not present during it's calibration. If it's C, M, or Y, check the EPU's in the revolver unit. If it's the black, check the EPU and the lifting clutch. If it's neither, try cleaning the IQC sensor or replacing it.

Also check the operation of the revolver unit, if that is your problem then you're in for a headache.

Firmware v340 does not contain a solution to the problem of error CE40

[emujo]

Its not firmware.."got this problem after I disassembled....". You may have left a connector for the xfer unit disconnected, or the color density sensor may be out of whack. Did you perform the developer adjustmenst, and other 05 adjustments after replacing the developer?

Do not forget to reset the counters for this error as well or it will come back.

CE40 Image quality control test pattern abnormality: The

test pattern is not formed normally.

remove bridge unit and belt cover ... whatch the image being formed on the belt.... see if the pattern is good
cut from manual

[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 (Note).
(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.) 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 to
576)".

Note:

Abnormal image:
Blank print, Solid print, White banding, Color banding, White spots, Poor transfer, Uneven image
density, Faded image (low density), Uneven light distribution, Blotched image.
