This is completely off topic from recipes and cooking but it will save you some time, money and frustration!
A while back I purchased a new HP wireless scanner/printer/fax one thing that sold me on the printer was that the ink was sold in separate cartridges so if one color was depleted you didn’t have to buy an entire new cartridge but what I didn’t realize until later is that if one cartridge was empty the printer would not print…not even if you selected to print in gray-scale which is an option but it still will not work! I rarely print in color, but I do print using black and fax a lot and need the fax confirmation report for my records. Ink and gas is expensive and the thought of having to run 10 miles to the store to buy an ink cartridge in a color I didn’t need to print was a ridiculous thought.
My printer uses the HP 940 Cartridges and after
fighting with the printer trying hard to get it to work, changing it to print in gray-scale and then doing research online at first I found that my only option was to run to the store and buy another blue cartridge just to print in black!! I decided to dig a little further and I found the tip below in a forum.
It worked on the 940 cartridges for me, I don’t know if it will work on other cartridges but if your printer uses 940s then it should work for you.
Remove the “empty” cartridge and place a piece of tape over the opening, letting the tape sag into the hole just a bit. It worked and my printer is back in business. This tricks the printer into thinking the ink sack is full.
A lot of HP printers use this same cartridge so I am hoping this fix can help quite a few readers out.
