Black will not print

In the middle of printing a large document my printer ran out of the 3e black ink cartridge. I replaced it, but when I went to resume printing only gray and the colors printed - no black. I went and bought another new 3e cartridge and replace the other. Yet, still NO black will print. Every other color and every other feature is functioning fine. HELP!!!!

Re: Black will not print

This may seem obvious but have you tried cleaning and refreshing the print heads? I've had a similar problem with only certain colors and the cleaning seemed to help.

Many printers require you to print a test page and go through a process to align the new cartridge. If you haven't done this I would suggest this as your first step. This will confirm if the printer is working.

If still no joy, disconnect printer from computer, uninstall it then reinstall it. Can often save hours of messing using this method.

Will not print in black. will print in color. I

Sounds like a badly clogged nozzle. If you are using aftermarket/refilled cartridges, the changes are the ink is not up to manufacturer specs and has dried and clogged the nozzle. The best way to clear this is to take a new black ink OEM cartridge and run the deep cleaning a number of times (at least 3) to see if the nozzle can be cleared. If you continue to use non-OEM cartridges, I would keep a set of OEM cartridges around for nozzle clearing purposes. Also, take the aftermarket ink cartridges back to the vendor and either get an upgraded cartridge or refund.
Let me know if this corrects the problem. Thanks.

IP4000 - How can I force the printer to use the large black (6) ink cartridge?

Do you mean the large black ink as in the 3e vs. the 6? If so, the large black, 3e, is a pigment based ink and the printer should only use it when print text and black and white things. The 6 black is a dye based ink and the printer should only use it when printing photos.

Ran out of color ink on cnnon mx310 ... want to

If when you attempt to print only with the black cartridge installed but it won't print, then this specific printer requires that color ink also be installed. Typical with most inkjets.

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.

3e Black cartridge won't print

I'm not an expert but I go through a lot of ink.. I have found that even with new ink some of the tanks of ink aren't any good especially with compatible which i buy a lot of because it's a lot cheaper (ebay). With that ink I have gone through 10 cartridges in a row before finding one that worked correctly again (I mean out of 100+ cartridges hitting a run of 10 that where bad but the rest good.)

Also, a tech for epson once told me to hit deep clean 7 times in a row before a head check to clean their nozzles.. That has helped with my printer and at Fry's electronics, they have a cleaning solvent in kit, haven't tried it, but i have run alcohol through mine but I'm told that is very ******* the print head (dissolves the glue).

Hope that helped..
