Re: blank printing

Look carefully at the new cartridge. Some of them have a clear film that has to be peeled off before it can be used.

I have a Dell 926 All-In-One InkJet Printer, I put a new black ink cartridge in the printer; still have plenty of color ink. When I have a document that I want to print from Word, it will sound like its...

Make sure you've removed the shipping tape from the cartridge's print head. More than likely the black cartridge is not disbursing ink - clean the print head carefully with "Q" tip and alcohol and see if black ink comes out slightly. Re-insert cartridge and try again. Perform "clean cartridge" in printer properties window.

My F4180 has stopped printing with the black cartridge. I have checked with different cartridges and have also uninstalled the HP software fully and then made a new installation with all new driver. No...

It's like the ink is not flowing at the nuzzle! To check this you take some tissue paper, fold it so that is is a little padded. Press the black ink cartridge nuzzle (this is the bottom part where the ink comes from) on it. If black in is flowing well, the tissue ahould come out blotted with black ink. If it does not, it means either the ink is blocked or the is finished. Try this with every black ink cartridge you want to test. 

If see the blot of black and the problem persists, clean the "electronic" contact side of the cartridge with tissue soaked in a bit of methylated spirit. Do the same to the area it makes contact with inside the printer.

Then try to print.

I keep getting cartridge error or it prints a blank page. There is no tape on the cartridge and they are installed properly. It prints sometimes but not all the time Printer keeps saying cartridge error

This has been just happening with me aswell - I just changed the colour cartridge with the black cartridge ran out but i kept it in as it told me to place one in. Trying to print out but black ink wont come - just blank pages - surely the colour cartridge can make black? However, if you have the colour cartridge and are on microsoft word or similar, change the colour of the writing to dark navy and it will print out documents.
