Cyan color will not print. I have done the 3-pass "Clean Printhead " cycle at least 5 times, waiting at least 30 minutes between cycles. No improvement. I have replaced the cartridge with a NEW HP 902XL cartridge. All cartridges are HP manufacture. Black and other colors are all working. Is there anything else to try?
