HP Envy 4500 Will Not Copy
Power up the Envy4500 printer by force pressing its power button. Wait until the printer becomes idle. Unplug the power cable with the printer turned on. Wait for a few minutes and reconnect the cable to the respective port of the printer and power supply. Do not use a surge protector for power connection as it produces power fluctuations. Turn on the 123.hp.com/envy4500 printer if it does not power up automatically. Perform a copy function and check if the problem is solved. If the copy problem continues, update the printer firmware.
