Canon imagepress c6010 Dens problem

[burak]

Hello again


I did the PT-LPADJ process. window value 1000
I removed the patch sensor and cleaned it.
I cleaned all the toner pipes + subhopper to see if it was clogged.
but the result did not change. the toner flow is fine up to the subhopper, but there is a problem between the developer tank and the toner calculation.
When I rotate the subhopper with my hand, the dens value is recovered. but the machine itself does not supply enough toner to the deveopler tank, the dens value drops to -6%, the machine gives e20 code.
I request your valuable help.

Do u have another developing unit to test on it?

If not try swapping the sensor with another unit.

And Check is the developing pressure good? When u push the unit to the drum , check if there is anything not right.

Send me a 50% black Pg and 100% black Pg.

Try swapping coronas

Did u try what i have suggested?

You can also try swapping the patch sensor.

Best of luck

Hello there,


I have Canon c6010 abnormal dens problem.
In ground works, the dens value decreases to -5%, the machine gives error e020-0481-05. In normal jobs, the dens value is around -2.50%.
I changed the developer and the drum today, the problem does not go away. I cleaned the atr sensor many times, the result did not change. I cleaned the laser and the result did not change. I use oem toner.
please help Attachment 50349

Maybe this info below could be of some help;check it out.

[Symptom]

Unit displayed a E020-0381. Patch sensors were cleaned, the code changed to E020-0481.

• E020-0x81: Lower limit error in light intensity on drum base (reflecting light intensity from the drum surface). DISPLAY > DENS > P-B-P-Y/M/C/K (Measured value of drum base) < 150 (x= 1: Y, 2: M, 3: C, 4: Bk)

[Remedy]

In this case, the Cyan Developer Assembly, was replaced to resolve this issue.
FM4-7440 DEVELOPING ASSEMBLY
