[Error Code] Canon IRC3380 ERROR E020-0021

[tomson25]

Dear All,

I installed a new Magenta Drum Unit in IRC3380,After that i am getting an ERROR E020-0021. How can I solve this problem.


Thanks

Could be developing cluth part no FM2-3581

0021= Indicates that the patch level is lower than the lower limit of the target although setting it as the maximum when initializing Magenta ATR.
Clean the ATR sensor window. Check the mounting of the developing assembly. Check the ATR sensor open circuit.

Then>perform a DCON clear followed immediately by a full auto gradation adjustment.

make sure to print out P PRINT settings before DCON CLEAR> u need them to re-input DC settings back in printer

u may need to Replace the ATR sensor

In the service manual the ATR sensor location not mentioned.Could you please send me the digram.

[1]Drum film thickness detection computes the film thickness of the photosensitive drum
[2]ATR control determines the amount of toner to supply
[3]Color Dmax control determines the best level of laser power
[4]Black Dmax control determines the best level of developing bias
[5]PASCAL control determines the best gradation table
[6]Dhalf control determines the best gradation table
[7]Abridged Dhalf control determines the best gradation table (abridged)
[8]Color displacement correction control determines the correction value of color displacement
[9]ATVC control determines the best level of transfer bias

ATR Control
The machine executes ATR control to supply toner so that the ratio between toner and carrier inside the drum unit may remain ideal.
1. timing for start-up
- When new drum unit is installed
- every print (video count)
- every 80-sheet (patch image reading sensor)
2. Particulars of Control
The machine computes the amount of toner to supply for each color, and supplies it to the drum unit.
The machine uses the following 2 types of data to compute toner amounts:
- Video Count (for each print)
The machine uses the video data arriving from the main controller to compute the amount of toner consumed, and makes up for it by supplying the drum unit with the same amount.
- Result of Detection by the Patch Image Read Sensor (to every 80-sheet *1)
The machine measures the toner image formed on the ITB using the patch image read sensor, and supplies the drum unit so that the density will be identical to the target density.

ATR-Related Error Code:
- E020-001x: outside correction range (upper limit) error 1
At time of installation or during replacement of a drum unit, the patch density data of the color in question as
determined by ATR control is outside the range of correction (upper limit).
- E020-002x: outside correction range (lower limit) error 1
At time of installation or during replacement of a drum unit, the patch density data of the color in question as
determined by ATR control is outside the range of correction (lower limit).
- E020-010x: outside correction range (upper limit) error 2
At time of printing, the patch density data of the color in question as determined by ATR control is outside the
range of correction (upper limit).
- E020-020x: outside correction range (lower limit) error 2
At time of printing, the patch density data of the color in question as determined by ATR control is outside the
range of correction (lower limit).

We are allways told to give the new drum a little shake before installing as the developer can stick at one end, did you do this?

Also have you tried putting the old M drum back in? does the error clear?

If this happened after changing the drum I'd bet some sensitive parts of my anatomy This is the right response. Take it, shake it, reinsert it. And I don't mean the sensitive parts of my anatomy.

I've had quite a few new drums where the auger snaps inside them and causes E20's. As said above put the old drum or another new one in and see if it fixes it. We always shake the new drums before putting them in so it loosens up the toner inside them to prevent the auger breaking.
