Flashing lights On/Off and resume lights are flashing quickly. Printer will not print any documents.

Would be helpful to know which operating system you are using and whether there where any warning light flashing. For starters review the following solutions.
Printer Does Not Start or Stops During Print Jobs

Inner Cover was open when you started printing.

Close the Inner Cover and press the RESUME/CANCEL button on the printer. The printer resumes printing.

Inner Cover was opened while printing is in progress.

Close the Inner Cover and press the RESUME/CANCEL button on the printer.

A page of print data being sent at the time of the error will be erased, so print that page again.

The printer has been printing continuously over a long period.

If the printer has been printing continuously for a long time, the Print Head may overheat. To protect the Print Head, the printer may stop printing at a line break for a period of time and then resume printing.

In this case, interrupt your print session at a convenient time and turn the printer off for at least 15 minutes.

Additionally, if the printer has been printing graphics or photos with intense colors continuously over a period of time, the printer may stop printing to protect the Print Head. In this case, printing will not resume automatically. Turn the printer off for at least 15 minutes.

Caution

The Print Head and the surrounding area can become extremely hot inside the printer. Never touch the Print Head or nearby components.

Out of paper.

Make sure that paper is loaded in the selected paper source.

Reload paper if no paper is found in the selected paper source (Auto Sheet Feeder or the Cassette).

If the same paper is loaded in the other paper source, you can switch the paper source with the Paper Feed Switch or the printer driver to continue printing.

If both paper sources have run out of paper, confirm the selected paper source and load paper there.

Printing documents with plenty of photographs or illustrations.

When the POWER lamp is flashing green, the printer or the computer is processing data. Printing large data such as photos or graphics takes time for the printer and the computer to process, during which the printer may appear to have stopped operating.

In addition, when printing data that uses a large amount of ink continuously on plain paper, the printer may pause temporarily. In either case, wait until the process is complete.

Note

If you are printing a document with a large printing area or printing multiple copies of a document, printing may pause to allow the ink to dry.

Please adjust paper size in printer properties.

Cancel button
Print cartridge status light
Resume button and light
Power button and light

- If the power light is flashing it means that your printer may be receiving data.
- If the resume light is flashing you may be out of paper, or you may have a paper jam, you may be printing a two sided document by hand and the first side has finished printing.
- If the print cartridge status light is flashing that means the top cover may be open, of there may be a problem with one of the cartridges.
- If all of the lights are flashing the printer may need to be reset.

Hope this helps.

This could mean that a 2-sided document was sent to the printer and the printer is waiting for the page(s) to be reinserted to print on side 2. Check your documentation or the HP support page http://h10025.www1.hp.com/ewfrf/wc/product?product=75045&lc=en&cc=us&dlc=en&lang=en&cc=us
for more information.

The power light blinking indicates the printer is preparing to print a document. The resume light indicates 1) needs paper, 2) a paper jam anywhere in the printer, or 3) the ready to print side 2 of the document.

I hope this helps.
