Canon imagepress c6010 Dens problem

[burak]

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 82754edf-7617-4794-add5-b65a3a6b93d5.jpg

Hello again,


Starter is new. I have made all the necessary adjustments.
but the machine seems to be unable to transfer the required amount of toner to the developer unit.
waiting for your valuable ideas

of course cleaned the patch sensor many times.

Perform PT-LPADJ and test

I performed the PT-LPADJ process.
but after 100 prints the error came back.
dens value decreased to 6% for black.
I couldn't find a solution

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

After cleaning the black patch sensor and performing the PT-LPADJ,check the values of Dens/window K.it shoud be around 1000 and also the value of P-DA-k and compare it to the values of the 3 other colors.if it is clean,it should give a low value;otherwise it means that the sensor is still dirty and should be replaced.

There is a thin plastic film on the sensor;so this sensor should never be cleaned with alcohol or any other solvent;you can use a blower to clean it.

Hope this info would be of some help to resolve this issue.
