Color cartridge #78 will not work.The one I took out was a #17.


Hello, if you lift the top cover there should be a little label with the correct ink cartridge numbers that you need to buy. I've got a Deskjet 845c, which is similar to your 840c, and the label shows 17 colour; 15 black. I suspect yours will be the same. No others will work as the printer was designed for those particular cartridges. They are still readily available in the shops or online. If you're in the UK try www.inkrite.com

Printer only prints magenta from the tri colour cartridge, have tried different new cartridges, same problem.


Stop buying cartidges. You already know they're not the problem. The problem is in the circuit to the cartidge. Gently wipe the circuit ends then retry. If not, buy another printer that accepts the same cartidges. Don't waste the ones you buyed.

Hp 840c no red printing


Dip the head area of cartridge in hot water by 2 to 3 seconds two or three times and use tissue to check the color, if all three color comes out to tisssue paper, then it works else you have to replace the cartridge.
