Just opened my new mfc240c printer and it wont print black ink why? only prints in color no matter how many times i clean the heads

It is possible the ink carriage and print head are very dirty and needs servicing.

if it is a new black ink cartridge and the printer still wont print black start by:

A: Simply making sure the settings are ok. To do this, go to file>print. When the printer box shows up. click properties.

From there, you will be able to see color settings. (ex. black, grayscale, full color.) Try switching to black or "use black cartridge only.

B. If "a" does not work for you, the print head which hold the ink cartridge is clogged or no longer working. Through the cannon window on the printer, try running a print head cleaning or any maintenance program.

If there's still no black, the print head has seen better days and needs replacing. Most of the time it is more effective to get a new printer.

If you did put in a new printhead, it means you need a new purge, or cleaning assembly. If it doesn't clean and prime the printhead properly, it won't print.

Well if you already installed a new black ink cartridge and still wont print, then try cleaning your printer head. It can be that the some ink was hardened and got stuck preventing you to print a black color.

I had this problem recently with my IP90. Both the black and color heads were clogged. After running the "canned" routines several times to clean the heads and deep clean the heads...still didn't help...here's what I did:

1. open the top lid to have the cartridges that are inserted in the print head move to the middle of the printer.
2. remove both cartridges
3. What is left there is the print head holder. Slightly move it to the right and gently lift the print head lock.
4. Grasp the print head and lift it out of the tank.
5. Have several paper towels hand and know that you will have color and bw ink on your fingers
6. Put the print head on the paper towel
7. Pour rubbing alcohol on the blk and color heads and let them sit of about 10-15 minutes.
8. after that dry the heads and re-insert them in the printer
9. I put new cartridges in the printer and ran clean and deep clean a few times.
10. My color and black and white print came right back!

Hope this helps.

Clean heads, clean heads, clean heads, etc. Then do the test print to see if the heads are open. I had similar problem with an Epson, had to clean the heads often, finally got to where the heads wouldn't clean so threw it away and bought another one (HP this time, the heads are included in the ink carts, haven't had to clean the heads at all.)

I have this same model printer and had this same problem. I solved it by running the cleaning cycle repeatedly (30 times or more). It nealy drained the black cartridge, but they're cheap compared to a new printer ($100 for the mfc240c that replaced it). Press the ink button to the left of the display. Select "test print" and "print quality from the menus, then hit print. After printing, the display will ask if quality is ok. Press 2 for no. It will ask if the black was ok, press 2 for no, if the color looks ok, then press 1 when it asks if color is ok, then press 1 when it asks to start cleaning. In a minute or so, it will beep and tell you to press start. Once the sheet prints again, repeat the same sequence. I didn't even wait for the display, I would just press 2,2,1,1, each time it printed. At first the black section was blank, the one dash appeared, then two or three. I gradually gained on it until I had most of them working again, then let it set overnight and ran a few more cycles the next day and it finally all started working.

Most likely because it uses color as well with the black. Some printers will not allow only 1 cartridge. You need both.
Thanks and keep me posted,
