Status messages

Warning messages

Error messages

Critical error messages

Status messages

Status messages reflect the current state of the device. They inform you of normal operation and require no action to clear them. They change as the state of the device changes. Whenever the device is ready, not busy, and has no pending warning messages, the status message READY appears if the device is turned on.

Warning messages

Warning messages inform you of events that require your attention, but they do not prevent the device from operating. An example of a warning message is CYAN INK LOW. These messages appear until you resolve the condition.

Error messages

Error messages communicate that some action must be performed, such as adding media or clearing a media jam. These messages are usually accompanied by a blinking red Attention light. Take the appropriate action to continue printing.

If the error message shows an error code, press the Power button to turn off the device, and then turn it on again. In most situations, this action solves the problem. If the message persists, your device might need service. Write down the error code, and then go to HP Instant Support to learn more about possible causes for the message. For more information, see HP Instant Support.

Critical error messages

Critical error messages inform you of a device failure. Some of these messages can be cleared by pressing the Power button to turn off the device, and then turning it on again. If a critical error persists, service is required. For more information, see Support and warranty.

Change device settings

You can change the device settings from these places:

From the control panel.

From the HP Solution Center (Windows) or HP Device Manager (Mac OS). For more information, see Use the HP photo and imaging software.

From the embedded Web server. For more information, see Embedded Web server.
