These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Blinking codes details to many popular brand TVs are given. Surf the site with patience. Do a search by type in the brand name of the device to the search box.

With paper loaded properly, turn off/unplug register, turn MA or Service key to "Blind" position (approx. 5 o'clock), turn on/plug in register. "Status-C" will print on the receipt. Some of these TEC's won't reset after changing paper, and this procedure becomes necessary after each installation of a new roll of paper.

you can get the trouble codes out by turning key on off on off on then watch the check engine light it will flash a number of times n pause this will give you codes to take to the auto parts store n tell them they will know most of them the service writer at the dealer can find the rest (example) blink blink blink pause blink blink =32 there could be several so do it a couple times to make sure you get them right and get them all

The error light that is blinking is actually blinking out a error code. In the back of your manual under troubleshooting there should be a list.

On a printer this new about the only error you should see is a paper jam. IF anything else is wrong I'd just put it in the box and take it back. Rarely do you see something fail this new these days. It happens but not that much.

Once you look up the error code you will know what the problem is. It could be a cable unplugged or a paper jam etc. I can;t see it being serious.

Go to "Printers and Faxes" or "Devices and Printers" and try printing a test page by right clicking on the icon and choosing printer properties. This will better define if the problem is something wrong with the printer or connection OR if it is a software issue.

YOU NEED YOUR FIRMWARE UPGRADED BUT ONLY A SERVICE TECH CAN GET IT AND DO IT.1 HOUR OF TIME SHOULD BE PLENTY AND THAT SHOULD INCLUDE A CLEANUP PROBABLY ABOUT 150 TO 200 DOLLARS

this indicates a the print head is not installed correctly or is faulty.

if the green and orange is alternating 5 times then it is caused by the sheet feeder.

you can unplug it for a long period of time and plug it back in and try it. Also, try using a can of compressed air to blow out any debris. Also, check HP's site under you model to make sure you can replace one cartridge without replacing the other.
Otherwise you may have a mechanical issue the would require professional repair, I think that model is about 6 years old and you would probably be better of buying new.

Sounds like your PCU is starting to fail. There is a cleaner roller that removes any remained toner and this could be shot. Try replacing the PCU. If this makes no difference it could be the fuser though this si less likely.
