Would think that you got a humidity issue there? Some moisture in the developer...
In that case the issue should return in time.

If you are a cowboy you can add a tablespoon of toner in there and run dev init again.
Don't blame me if this don't work. Been taking developer way past life with this trick but not recommended where good quality is needed.
Before you know it you could have a nice coating of toner everywhere around the imaging section.
The new concentration includes toner, paper dust, common dust, and human skin cells.

Thank you for your suggestions! I really did not know that this dipswitch gives effect after 1000 prints. I will try your ideas, as soon as coronavirus leave us alive

Let me correct myself.
To get the prints darker sould not take too long as it needs to add toner.
Reducing the density would take that long.

Did you add a small amount of toner and the ran dev init?
You can always add but if you dose in with too much toner is would fog up the machine or give you nasty background.

Hello guys, I returned to work after long time due to pandemic.

So today I turned off Drum Potential Sensor with dipswitch, tried to print a number of sheets and density started becoming higher, after 30 pages it became excellent. So as it seems DPS is dead there and I'm going to change it with new one.

Thank you all for your suggestions and attention!
