Simple answer to this (and I'm sorry you won't like this)...

Replace your printhead but first, check the warranty date on the printhead and then call HP support and ask politely/firmly for a replacement.

HP are well aware of issues with the black part of the HP88 printhead (the one used by the L7000 series MFD) and shouldn't argue too much.

Color Ink prints fine but Black ink will not print. Have replaced both black in cartridges and Cleaned several times. Have turned off printer and computer after cleaning. Nothing working.


You could clean the black ink cartridge. For this you need to remove the black ink cartridge which is present in the printer. In order to clean the laser or scanner block you could use a cotton swab as it would fully clean the dirt. You need to clean the grime and the dried ink present in the printer. This would remove all the hindrances which prevent the ink from flowing. Cleaning the printer heads would also help to solve the problem.

I was printing several pages & it just stopped working. the ink button & on button flash. Changed the ink cartridges but still get the same blinking with no printing. Turned both the computer...


Press the Ink Cartridge Replacement button and check the flash pattern of the control panel lights:
ERROR and POWER lights flash at the same speed = replace black cartridge
ERROR light flashes twice as fast as the POWER light = replace color cartridge

Button flashes, won't print


Actually, I figured this out all by myself. After I'd tried everything else, I took out the black printer cartridge and noticed there was black ink smeared all over the back, so I took some cleaning solution that came with some ink refill kits I had, cleaned off the contacts on the cartridge and on the back of the printer itself where the cartridge meets the printer, and it suddenly started printing again. TaDa! It's going again!

HP 3310 says "Black Cartridge Empty" when new one is installed.


remove the black cartridge/ place a piece of scotch tape on the left side of the gold top gold contact on the back of the cartridge, put back in the printer, remove the cartridge again and put tape on the right top gold contact on the right side of the cartridge, put back in the printer, remove cartridge and take off the two pieces of tape, should work good for you now/ It no doubt will print out an alignment page now.

Ink cartridge problems


exchanged the black cartridge (57): the printer told me there was a problem with it, that I should remove it and re-insert it. I did, the ink button still blicks. After several efforts the printer started to work again, printed one document and then told me there was a problem with the colour cartridge. I removed it, re-inserted it several times. Finally a test page was printed - everything was okay.

Then the printer refused to print anything - the yellow LED lamp blicks continuously. Have turned the printer on and off, have also shut down the computer and re-started.

The only thing that will work now is the black cartridge, if I remove the colour one.

Replaced empt 3E cartridge. Now it won't print


I had removed and reinstalled the empty 3e cartridge. Sorry for the Confusion. I hadn't put a new 3e cartrige in until today. Them I ran " deep clean" twice. The printer works fine. I still don't understand why the printer wouldn't print color, when I was had set the printer to print in color when my 3e cartridge was empty and all colors including the 6 black showed full.

Printer will not print


Ren, Does the printer show the cartridges have been changed? If the printer doesn't recognize the new cartridges, turn off the computer and unhook the printer, unplug the printer from the computer and electric. Turn on the computer so it boots without the printer hooked up,(2x) then shut down again. Rehook the printer and plug it in then reboot the system. http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?BV_UseBVCookie=yes&oid=41661&prodoid=46048263&infoType=Downloads&platform=All You can also find updated drivers from epson from here. Good Luck, Tim
