After your printer has completed its initial startup you should have a solid green light. If the light indicator is blinking or orange often this is an indication of a printer error. For example, this could indicate a paper jam, issue with the ink or toner cartridge, or other serious error.
Because there is no standard to what a blinking light or orange light means if you're getting either of these we suggest referring to the printer documentation for troubleshooting steps or methods of determining what the status indicator is reporting.

This is generally caused by cartridge, make sure the cartridge's connectors (interfaces) are cleaned and not ink or dust stuck on it. for further reference, you can see this http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=125&prodSeriesId=1845551&prodTypeId=18972&objectID=c00818561 Good luck..

Refer to printer documentation

The BJC 3000 will flash two different colored lights in a pattern to signal several different errors. From the documentation I have the two colors are orange and green, could those be the colors you see? At any rate here is the code: Two orange flashes: Out of paper, paper jam, or paper feed error. If no paper is loaded in the auto sheet feeder, or if the paper is not loaded correctly, set the paper correctly and press the Resume button on the printer to continue printing. Three orange flashes: Paper jam. If paper has jammed in the printer, carefully remove the jam and press the Resume button to continue printing. Four orange flashes: A tank inside the BJ cartridge (print head) is out of ink. Replace the empty BJ tank and press the Resume button to continue printing. Five orange flashes: BJ cartridge is not installed properly. Remove and reseat the cartridge correctly. Make sure the orange protective cap and tape have been removed. Make sure the blue locking lever is locked down securely. Six orange flashes: BJ cartridge (printhead) is not installed. Remove and reseat the cartridge correctly. Make sure the orange protective cap and tape have been removed. Make sure the blue locking lever is locked down securely. Seven orange flashes: BJ cartridge (printhead) is defective. Remove the BJ cartridge and check that the contacts on the cartridge and cartridge holder are clean. Make sure the orange protective cap and tape have been removed and reinstall the cartridge. If the error occurs again after you resume operation, you may need to replace the BJ cartridge. Eight orange flashes: Waste ink absorber almost full. The printer has a built-in waste ink absorber to hold the ink that is consumed during print head cleaning. This error indicates that the waste ink absorber is nearly full. Press the Resume button to skip the error so you can continue printing. The POWER light flashes orange and green alternately: Service error. A service error means the printer requires the attention of a qualified technician. If you have any more questions let us know otherwise please don't forget to rate this post.

Flashing resume light also can mean:

1. cartridge is missing or an incorrect print cartridge is installed
2. cartridge is out of ink
3. dirty cartridge contacts
4. paper jammed

Check are cartridges firmly snapped into place and not empty. Use water to wash copper on cartridges if contacts are dirty.
