Could be a faulty toner, or it is in a room with too high a humidity (Toner clumped up)
Try shaking the toner before putting it back in.
Do not shake it hard, be very careful.
It would then seem that the Cyan cartridge is broken, it would need to be replaced, depending on life of it, I would call Xerox and ask about reimbursement.
When you insert cartridge it pushes a white spring back so what I did was I removed cartridge pushed the spring back with my finger and with the keyboard spray I cleaned it as well as with wipes several times. Then walla it detected the new cartridge.
