'Warming up' or 'Scanner failure' messages
This error usually occurs when trying to scan or make copies. The scanner bulb is not hot enough or the electrical conditions are not suitable for the HP All-In-One product.
Follow the instructions listed below to resolve this failure.
NOTE: Make a test copy of any document once each step is completed.
If this copy is successful, the scanner mechanism is functioning correctly.
If the error appears again, skip to the following step.
The scanner lamp lighting should be viewable under the scanner glass right or left corner.
1 - Scanner lamp lighting
2 - Scanner glass
NOTE: The lamp will turn off when the unit enters the Save Energy mode. The unit will return to the Normal mode as soon as any key or button is pressed and the lamp will light again.
If the scanner bulb does not light up, the HP All-In-One product may be defective.
Make sure that the room temperature is suitable for the HP All-in-One product.
NOTE: The correct environment conditions for the HP All-in-One product are listed in the User Guide provided with the unit.
Perform a Power Cycle on the unit by following the steps below:
Turn the unit off.
Unplug the power cord from the unit.
Wait 30 seconds, and then re-connect the power cord to the unit.
Turn the unit on.
NOTE: Sometimes, unplugging the unit and plugging it back in will solve the issue. Be sure to plug it into a grounded outlet, using the power cord provided with the unit.
Check the power connections:
Make sure that the unit is connected directly to the wall outlet and not to a power strip.
NOTE: If the unit works properly when plugged directly into a wall outlet while disconnected from any power strips or surge suppressors, the power strip or surge suppressor may not be allowing enough voltage.
Try a different wall socket.
Every PC provides a standard power cord; it is possible to use it to check whether the electrical failure is prompted by the cord or not.
If the Warming up or Scanner failure error messages persist, please move the unit to a different room or building to verify that the building (or room) is grounded properly.
If your HP All-in-One product uses a external power module, check the power module part number against the part number listed in the User Guide to ensure the proper power module is being used.
If both part numbers do not match and your product is still under warranty, please click the Contact HP link at the top of the page.
If your product is out of warranty, please click the How to Buy link at the top of the page.
Perform a Partial Reset by following the steps below:
Unplug the power cord from the HP All-in-One product.
Press and hold the appropriate button combination for your HP All-in-One product. The appropriate combination for your model can be consulted in the HP All-in-One Products - Performing a Partial Reset of the All-in-One document.
While still holding the buttons down, plug the power cord back in. Release the buttons after the HP All-in-One unit displays the Partial Reset message.
Make a test copy of any document.
If this copy is successful, the scanner mechanism is functioning correctly.
If the error appears again, click the Contact HP link placed at the top of the page for additional support.

Every time the unit is turned on, the scanner carriage should move. Sometimes, when the scanner carriage returns to its home position, the carriage could crash and make a loud noise.
Within a few seconds, the unit gets blocked, and the front panel display shows a Scanner failure message.
Scanner noise could also be caused by the scanner sensor inside the HP All-in-One product being damaged or not properly in place.
