Change developer and/or check dev gears if broken

[m_donakov]

I check dev gears are ok, change developer from working machine and same problem.

Ok. You cant resolve this kind of problem with a firmware upgrade. Check 3222 and 3201 for the affected colour. Also when doin a force toner check if 3201 lowers down or goes up. Does the toner bottle move? Have you tried with another toner bottle?

[m_donakov]

I tried forced toner suplay and print test page, not adding tonner. One more thing that confused me more is that from 10 time traing once add toner normaly

[m_donakov]

Toner turns, and with another botle same problem.

Again check 3201 and 3222 and post here the values.

[m_donakov]

3201 - 2.18
3222- 1.71

99% the pump. Did you change it to a brand new or used pump? If new pump, try development unit.

dont reset anything, consider this as a warning

Wich colour i affected? Be careful with the tube beeing blocked by itb if the wrong pump is installed in the wrong place, for example placing black pump in the yellow place, its tube will be blocked by itb as it has a different angle
