Question about HP DeskJet 6840 InkJet Printer

1 Answer

Replaced the black cartridge on my 6840 (which had been working fine until now when it ran out of ink). I keep getting a message that there is a problem with the right cartridge and to remove and replace which I have done to no avail. Thanks to anyone who can help. I noticed that when I insert the color cartridge I get a "soft" click which I don't get with the black one. Holden

I have replaced black ink but printer keeps telling me to replace black ink cartridge


If the it's a remanufactured cartridge (not genuine), the printer will not detect the ink in the cartridge.
If it's genuine, you might want to give Lexmark's technical support a call to have the cartridge replaced.

My black ink ran out so I replaced the ink


Hi:
I have used the printer series that you have for years, and once in awhile, I get a new cartridge that won't immediately print. Often, there is just a bit of dried ink residue on the print head, and that won't allow the cartridge to work correctly.

Some simple things to try are :

1) Remove the black cartridge. and take a damp paper towel and gently swab the print head area. Next, apply some pressure to the sides of the black cartridge, until you see black ink oozing out of the print head. Repeat if needed. Once the ink starts flowing, blot off the excess, and install the cartridge.

If you can't get ink to flow, then the cartridge might be bad. Most of them have an expiration date on the packaging.

Replaced black ink cartridge and printer keeps asking to replace


The message that persists in saying to "replace black cartridge" could be due to a defective cartridge chip. The chip maintains counts and tells the printer when a new cartridge is installed. If you cartridge is remanufactured, they may have neglected to install a new chip.

Regarding the new fuser not working, I'll have to get back to you on that.

Why won't my CX9400F recognize Epson ink cartridges


The Epson CX9400F printer seems to require replacement of all the color ink cartridges, even if only the Black is empty.

I print almost exclusively in Black, but with my first change of Black, I was forced to change all the color. At the time I thought Epson did not provide completely filled color ink cartridges.

Just yesterday, I replaced Black and the printer complained it did not recognize the rest of color cartridges. So I replaced all the other color ink cartridges and now it works fine.

You might want to check out www.clickinks.com for cheaper, mail order alternatives which are Epson ink compatible, if you are not in a hurry.

Black and white not printing correctly, color is fine


If you are not using Epson ink, your printer will do this. Epson printers hate knock-off ink. Always use Epson ink if you want to keep your printer working properly. To solve the problem you are having, try cleaning the ink tubes. Make sure you re-install them properly. Hope this helps. Charlene

No black print


I just installed a new black ink cartridge and it won't print. My new color one will. It worked fine until it ran out of ink and I replaced it with a new one.

Not printing after color cartridge ran out - new black cartridge installed.


Yes, this printer has fixed printheads and must have ink in each color to prevent damage to the printheads. Even when printing black only each color is spit in the servicing area to keep the printhead unclogged.
