Konica pro 1100 c-2802 low density

[Lordnixon]

After replacing the developer, I have the error c2802. Adding toner to the block solves the problem for several thousand prints. So far, I have ordered TCR, TCB, but I am not completely sure that they will help(delivery times are long). The intermediate block is full, it works during printing, but the toner still goes away (in spurts, in the SM it is specified as normal work)
count 4kk
Before that, the error appeared on the previous planned replacement of the developer, but everything was resolved by itself. Unless the density was not so great. Adjusting the expert settings helped(offset to low, max density).
1) idc - clear
2) IO check motors -OK
3) FW g00-90
4) icp 201 -OK
5) hopper -OK (in check mode ok. are gear slips possible in normal operation?)
6) recall data in process adj not active, but 91-00 was completed

Simple question did you initialize the developer after replacement? Service mode > Process adjustment > Peculiarity adjustment > Toner density sensor init.

yes
moreover, I replaced the new developer again

Ok just double checking.

How old is the drum and charge components in the machine. How is the print density? If you go to Service mode > Machine adjustment > Copy density adjustment > Print screen or follow menu numbers 1,3,6,2. You can use the machine as a copier even if it has error codes on it. I do that to use the machine if i have to wait for new developer due to the error C2803. If you use this mode how is the density of the copies.

It could be as simple as one of your PM parts that is over life and causing poor correction patches.


Change drum, dev and charge at the same time will assure that patches will be developed properly.

Haven't seen any mention if OEM supplies being used or not.

Re: Konica pro 1100 c-2802 low density

Looking at the sample images the density is very low.How was the density just after replacing the developer? If it was nice and solid then it could be a toner supply issue or bad sensor values from the TCB.

Used original parts, original toner, etc. Sorry, my English level is not that high.

No need to worry just use translator and right technical knowledge.
You literally have to stick to allan advices that man knows his stuff...and many more

it was nice and solid ^^ after 100 full coverage prints - look 2nd image. In normal printing mode, about 5k will be printed before the density drops and another 3-5k to c2802
1. I'm also leaning towards to TCB or TCRS. waiting for parts
2. the toner is delivered in small portions only during printing. I don't know if this is normal

Then to wait and see if the TCB and TCRS makes the difference. Keep us posted.

In normal operation the motor on the sub hopper pulses continuously. Short rotations.

Ok got this advise form a big KM importer. Have not tried this myself but will have a go at it when i am faced with the C2802 and C2803 error codes.
Said that this works. Difficult to except the solution.

Remove the frosted lens from the IDCS exposing transmitter and receiver part of the sensor.
If you do this please let me know is that makes a difference.

Don't discard the developer just tone it up and initialize it again.

Also if you do the particularity > gama auto adjust check the error it gives there and check the meaning in the service manual.

Under Service mode > Machine Adjust > IDC Sensor adjustment should be done in the case of poor density or sensor replacement.
