I have the same problem. Changed cartridges many times before but did not have any problems. This time the orange light keeps blinking after putting in new cartridges.

SOURCE: third light from the right keeps blinking printer

I had the same problem and the following worked for me: I used a cotton swab with alcohol to clean contact points (copper colored dots) on the back of the ink cartridges themselves. I also gently cleaned the brass-colored pins in the cartridge slots. Hope this solves your problem.

Try cleaning the paper pickup roller, see if that helps.
If it is better, but still not perfect, fit in a new one.

Hi! I have a huge problem with my hp deskjet 940c. It won't print colors - only pink! I have bought two new print cartridges, but it's still no good. The black one is okay. Can you help me?

The issue here is that Most HP printers after a certain amount of years of use have that issue, mine was with the black cartridge so i bought a new one from best buy for about 30 bucks not bad for a decent all in one printer

Time for a new printer. All inkjets are made to just last 3-4 years. Yours is a 5-6 year old. Good replacements can be had to $100 or less.

Canon i9100: colors printing incorrectly

I've had the Canon i9100 since 2003 and have excellent photo printing results. In 2009 it started playing up and I'd gt some banding. More recently, black didn't want to print. It was as though the black ink in the print head got dry some days.

April 2010 - The colours started printing strange and I bought a brand new print head and installed it. Only takes a minute. Still had an issue with photo printing. Black and white was excellent but colours weren't true.

Found advice online to try cleaning the print head to print head carrier electrical contacts by rubbing them with a rubber eraser.

I did that and now I'm getting perfect colour photo prints again.

I had been thinking about buying a new A3+ printer but this is old printer is now working as good as new.

Printer will not work

Not sure if you can do this, but I have used my 940c HP Inkjet successfully since it was new several years ago. I have found that anytime I have had any problems at all, I just unistall it and reinstall using the CD's that came with it. It has always solved any problems, in general. Specific problems can be taken care of by reading the Toolbox that is installed with the CD also. Good luck.
