IR6800 No Yellow printing.

[BobComeau]

Hi All, Started working on a print job that was going quite well for a while.

Then, we got an error E00003-0053. Cleared it once and it went away and we were okay for while longer.

Then, we got a different error E000020-01A9. Reset the power and it too went away for a short while.

Yellow was starting to fade. Prompted for a new cartridge, installed it. No yellow is coming out at all.

Started getting another error E000020-01D2, a couple more times, then E000020-02D2. Most of the error texts refer to a possible poor connection, or a patch detector being defective.

Before I get into this tomorrow, does anyone have any suggestions?

Thanks!

the developer to become under toned; ATR Sensor, Salt Sensor, weak Starter, DC Controller and Toner Supply Drive System.
If possible make 10 color copies to force the ATR sensor to take readings. Then compare the SGNL reading for the color that is generating the error and additional colors in Service Mode; COPIER>DISPLAY>DENS>SGNL-Y/C/M with the Initialization setting in COPIER>ADJUST>DENS>SGNL-Y/C/M.
COPIER>DISPLAY>DENS>SGNL-Y/C/M arethe ATR Sensor readings of the Starter in its present condition and should be within +/- 100 of the Initialization settings.

COPIER>ADJUST>DENS>SGNL-Y/C/M arethe Initialization settings that the copier maintains and are usually between 400 and 650.

2. If the Initialization setting is outside these numbers the Starter will need to be replaced.

When replacing the Starter, make sure to execute:
- COPIER>FUNCTION>INSTALL>AINR-OFF - set to 1
- COPIER>FUNCTION>INSTALL>STIR-Y/C/M
- COPIER>FUNCTION>INSTALL>INIT-Y/C/M
- COPIER>FUNCTION>INSTALL>SPLY-H-Y/C/M

After Initializing the Developer Units print a P-print and keep it with the copier; COPIER>FUNCTION>MISC-P>P-PRINT


3. If the ATR Sensor reading is over +/-100 of the Initialization setting the ATR Sensor, Salt Sensor, Transfer Belt and DC Controller are suspect.

Check that the Transfer Belt is in good condition. The Salt Sensor looks at a patch of toner that is generated on the Transfer belt for each color and determines the amount of toner that is in that patch by the amount of reflected light. If the Transfer Belt is not working properly the patch will not transfer fully from the drum and affect the Salt Sensor reading. Check the status in COPIER>COUNTER>DURBL-1>TR-BLT and replace it if it is over its rated life.

If the Transfer Belt is within its rated life then replace the ATR Sensor and Salt Sensor. If the error continues replace the DC Controller.

4. If the error is indicating an "under toning" condition shortly after the Starter has been replaced, check the Toner Supply Drive Bushing for damage. If the bushing is damaged the Toner Supply Drive Gear and Toner Supply Gear do not mesh and toner is not supplied.

We have some success, for now at least.

I don't have any of the parts mentioned, so I had to hope a good cleaning with particular attention to the contacts mentioned would do some good. After I had it all back together the all the colors were working after a couple dozen pages. Hopefully we will be able to finish the job we were in the middle of.

You mentioned the starter, and from your figures I think I better track some down. Here are the values from the screen: SGNL-Y: 383, -M: 364, and -C 424. Any guesses as to how long these will last, or will running at these values cause any damage?

Thanks for your help!

it all depends what u are printing / Canon sets numbers to a 6%-8% Standard TONER USAGE.
Large area usage effects the DENS-SGNL numbers greatly/ and can cause under-toning / these machines are not printing presses

keep an eye on monthly volume/set up a good maintenance sch.with a tech.

"Check the Developing Bias Connector in the front of the Rotary Assembly for Yellow"

Has anybody replaced the dev bias contact plate that sit's on each colour unit (part of item 80) if so have you a part number please, I've got one missing. Item 80 on the parts list is the complete carousel or rotary unit and even that has no part number!!!!

Your about Four Months late on your response/ Poster took care of issue by following my instructional post above.

May be I should have started a new thread
I am after the part number of the Dev bias contact strip their are 3 in total. 1 of them spring tensioned on each colour unit, as the carousel rotates to the correct colour they complete circuit for D/Bias.
Thanks.
