If your HP 8610 printer offline, it's getting to be that it's turned off or in sleep mode. Other concerns include network issues, cartridge ink issues, and a faulty USB cable link. The reasons are often the printer is often turned off or in sleep mode when it displays a blank screen. The matter is usually overcome. Disconnect the power cord from the socket. Await a flash then re-insert it to resolve the problem. If things persist, you'll get to seem at other possibilities. This might be due to faulty USB connectivity or a network problem. To elaborate, the USB connection between the printer and thus the pc must have come off. Tighten the sub cable at both ends.
