Need help with my konica c451

[zeyad]

did you go thru the initialization process?

i am sorry I did not get your question. However, I have pulled all the old powder from the drum unit including the one on the magnetic roller then i have added the new developer powder.

but i have checked the drum it seems fine. it is almost clean.

Aftermarket developers don't work well in these machines. Buy new yellow Image unit and line will be gone. Make sure it is genuine Kon/Min
