E-451c CE40 code.

[Guest]

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

its got t410sy0u340

IQC

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

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.

I'm having the same problem CE40 Error. I'm using Toshiba e-Studio 2500c. I did all the steps which you have mentioned. It seems my Yellow toner has the high density pattern abnormality. ( Returned the value 652 for 05-390 ) What can I do to rectify this issue? Any advice will be a great help . Thank you in advance

PS : By the way in the self test pattern yellow is not getting printed.

If you are getting no yellow the Developer might have been pulled out of the unit. Take the Y unit apart and check the developer level, mag roller rotation etc. Fix that problem and then take apart and clean all the units, especially the charges.

Thanks for the reply. I checked the developer unit. It seems okay, I did clean the units as well. As I stated above it seems my yellow toner is indicating as high density. What might be the cause for it? Is there any way to fix this problem?

You could try cleaning the IQ sensor in the middle underneath the belt near the 2nd transfer point. It's covered by a shutter and is pretty apparent when the belt is out of the machine.

If it really is high density you can adjust it down in 05-205 and then run a bunch of skyshots to get the toner out of there. Also check the doctor blade gap or the mag roller brush adjustment.

CE40

I''l post this.. It may or may not help...I was in Chicago at a Toshiba color school recently... We discussed the fact that Toshiba has changed the developer mag rollers in the copiers from a " smooth, sand blasted type" to a "knurled or ribbed type".. The instructor mentioned that this has been solving CE40 errors,among others. The smooth mag rollers wear down and cause density issues and readings. You can lightly sand the surface of the mag roller or replace with new type ribbed mag roller.

Thanks for the help ToshibaTech and tech07 3 service technicians came today and did some cleaning and checking stuff, but no good. They said that I have to send it to the workshop as they were not able to detect the fault. I live far away from the Toshiba workshop town and transporting it there will be a real pain in the as*. I'm able to get the black prints and copies by doing 08-556 to 0 and 08-557 to 0 ( Entering invalid numbers ). But auto calibration fails if I enable them and displays CE40 error.

I noticed my yellow toner has been spilled where it goes to the developper unit. I mean the small nozzle in the toner and the opening. I cleaned the powder and tried again, but same results.

By the way you have stated to do "bunch of skyshots to get the toner out of there" Can you please elaborate how to perform this? Thanks

Let me rephrase it. No guarantee this would work but you could go into normal mode with 556, 557, and 4546 set to zero (set them back when you are done and it is fixed 4546 can be set to 5.)

Then take the Y toner out and go into normal mode. Hit full color, hit image then monocolor then yellow, make a bunch of yellow sky shots (lay a piece of paper so that it only covers about 2 inches (50 mm) of the glass to the right of the slit glass). You're just trying to run a bunch of solid yellow copies so that it runs some toner out of the DV.

After that you can go and run 05-201, set your 08 codes back as mentioned, and then try to run 05-395.

Again, it may or may not work just an idea I have used a couple times before on other machines. It --shouldn't-- be out of wack but if it is you might have a toner sensor problem. Honestly it's not usually the yellow that causes a lot of problems for some reason. More often it's the other three. I hardly ever see Y developer depleted but the Y toner does dust more than the others. The air flow in these machines is peculiar.
