try to check the drum unit...

[akbareshghi]

drum unit is clear
my guest is developer (mixing with toner)

[adween]

if like that just take out the toner bottle and print until toner sign on. after that u put back the toner. did u use original toner? if u use compact toner i think the toner is not suite with your dv type.

I used Developer type 21 for 2035(pack of 1 kg but i pour one-half of it into the dv unit)
I used Original toner
I solved the problem with 50 Copies(full black) and copies become clear
but i changed the code of 2220 and because of my Td sensor failureToner Supply mode is controlled by Image pixel count not by TD sensor
Please guide me for setup current high quality copies for future because after 200 copies or higher the problem of dirty coping reappeared
my guess is the wrong setting of my machine , because the all of parts and consumable is new and recently is replaced(Drum , Blades, developer , Charge roller , pad Charge roller ,...)
thank you

Try using developer type 24. I thought that's the correct one for the 2035. Your quality problems are caused by the wrong type and amount of developer.

What's the condition of the dv-unit?

Correct developer for 2035 is Type 26 B0799640 and use the full pack!!

Type 21 is for 2090/2105
Type 24 is for 1060/1075/2051/5000/6000 etc

Get the correct dev, the correct toner, maybe new drum and blade, then re-enter all the settings from the machines birth certificate, initialize dev, run up auto process codes then see how ya go from there.
