If your HP printer has any problems with the hardware, such as a paper jam or a carriage jam, incorrectly installed cartridges, or even low ink, it could appear that print jobs are getting stuck in the print queue. Blinking or flashing lights on the front of the printer or erratic or unusually noisy operation are some indicators of hardware-related problems.
If you notice any of these issues, HP recommends searching for a document that is more specific to the hardware issue. For example, if you see blinking lights on your printer, or there is an error message on the computer, go to the HP Customer Support
page and search for the specific error message or blinking lights.
Otherwise, continue with the steps in this document.
