I have same problem BUT I am running on ORIGINAL XEROX CARTRIDGES !!!
reseating the cartridge and turning off the machine did not help !!!
They may be compatable with a 6022, but they are not compatable with yours.
This explains the why portion
I received a message "Replace Black Cartridge," so I did.
After replacing the cartridge, I received an error message: 009-953 Reseat Cartridge.
I removed it and replaced it, tried another new cartridge, turned the machine off and replaced it again. Took out all cartridges and cleaned the insertion spot as the online manual suggested. Also tried unplugging it for 10 minutes. Nothing is working. This is a near band new machine - purchased in September, so 3 months old.
Note: I work for a non-profit, so we do not use Xerox brand cartridges, but after market or third party resources sold on Amazon as compatible. However, keep in mind, that these are recycled xerox cartridges but they are not working.
