Question about Brother MFC 420CN All-In-One InkJet Printer

1 Answer

Changing ink cartridges

The printer said I was out of I replaced the cartridge. After replacing it asks "Did you replace Magenta?" I said "yes". Now it says "No Cartridge. Open scanner cover, then reinstall ink cartridge" I actually went as far as replacing ALL the color ink cartridges that weren't even empty, and it still gives me this message. Why is it not recognizing the new cartridge? What can I do to reset this? Why does my printer use so much color ink when I rarely ever print in color?

Re: Changing ink cartridges

Do you use generic ink carts?
Those do make a lot of trouble with different errors.
Use another cart and it should disappear.

The technique of brother printheads demands some ink to keep the printhead working. Otherwise it will dry out. Therefore the machine runs some auto cleaning cycles (about once a week).

You should set date and time and leave the printer on power (You can turn it off by pressing stand-by-fax. But do not unplug/disconnect it from power outlet. Otherwise the printers logic thinks that if the printer is reconnected that it is newly initialized and pumps a lot of ink into the waistinktank).
The amount of ink when running auto cleaning cycles is about 1/10 of the amount of the initializing one!

Genuine brother ink cartridge not detected by printer on DCP J315W printer

This is a common occurrence for these machines. They can get confused when cartridges are changed before they read as empty.

To correct this.
1) Unplug the printer from both the Power and Computer and remove all cartridges closing the cartridge access panel.
2) Plug the printer into the Power only and turn on. The machine will complain about no cartridges, this is fine.
3) Open Ink access panel and insert the first cartridge (Black is most common and close the panel.
4) The machine will complain about the missing cartridges. Open the panel and insert the second cartridge in the sequence and close the panel again.
5) Repeat the process for the third and fourth cartridge.
6) Once all cartridges have been installed the printer will ask if you have replaced the cartridges. Say no to the Black, Cyan and Yellow but yes to the Magenta and it will display the correct readings.

If this process fails to read the cartridge still then there is something wrong with the sensor inside the machine which probably means new machine.

How to replace a brother catridge.

The Brother MFC-240C uses an individual cartridge for each color (black, yellow, cyan, and magenta). When one of the cartridges is empty or near empty, the printer will tell you to replace that ink cartridge.

You can buy the cartridges individually, or you can buy a pack of all three color cartridges or a pack of two black cartridges. To replace one of the ink cartridges, follow the steps below.
All four of the cartridges are located on the right front side of the printer, behind a gray plastic cover. Pull the cover forward from the side, where there is a slight cutout for your finger to grab. When the cover falls forward, you'll see the four ink cartridge holders, coded by color.

For the ink cartridge that you need to replace, push down on the purple handle for that color. The ink cartridge holder will open and fall forward, revealing the ink cartridge itself. Push down on the cartridge holder and the cartridge should pop out toward you a little bit. Grasp the cartridge and remove it.
Open the new cartridge and remove it from its wrapper. Discard the yellow cover, unless you plan to use it for the old cartridge.

Insert the new cartridge into the correct slot (from left to right, they go black, yellow, cyan, magenta) so that the word "brother" is right-side up and located toward the top of the cartridge. Once the cartridge is most of the way in, push the ink cartridge holder up by the purple handle until it snaps into place.

If you are replacing more than one color, repeat this procedure for each cartridge. Then, when you are finished, close the ink cartridge cover.

If you were out of ink or low on ink, the machine should recognize the new cartridge and perform the calibration process. If it doesn't automatically recognize the new cartridge, it will ask if you have changed one or more of the cartridges. Press "1" for Yes when it asks about a color that you replaced, or "2" for No if it asks about a color you didn't replace.

Once the printer comes back up to the ready state, print a color test page to verify that everything is working. If the test page comes out okay, the new cartridge is fine and you can either discard the old cartridge in the trash or save it to recycle. (But don't get rid of it before you are sure that the new cartridge is recognized and working correctly.)

Keeps asking for ink and it has ink

Try removing, and then reseating the MAGENTA cartridge.

If you replace the MAGENTA toner-cartridge, does the problem go away?

How to refill pixma mx700 magenta ink tank without

The colors are individual. That machine takes the Canon CLI-8. I would suggest reading your manual on what the procedure is for changing the ink cartridges out, it typically varies slightly by machine. There should be an option somewhere one of the menus to change the ink cartridges. When you buy a replacement be sure you buy from someone who isn't trying to scam you. I would recommend Cartridge World, of course, or OEM. Do not use cheap online cartridges, you will only have headache later.

Printer asking for replace of magenta toner, replaced it, still asking for magenta replacement. Have taken it out several times and reinserted.

I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink cartridge?
Please consider the following:
If you are using a refilled or third party cartridge that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks causing problems with print quality or damaging the physical printhead.
If you are using factory new cartridges, then please call the manufacturers Technical Support for assistance with the warranty on the cartridges

Install black cartridge, but will not print

Lets do it this way. Follow these steps again carefully and try to install the Ink.

Follow the instructions below to replace the ink cartridges.
Replacing the ink cartridges
1. Verify that the unit is on.
2. Open the ink cartridge door.
3. Squeeze the gray tab below an ink cartridge slot to release the gray latch and then lift the latch.

1 - Ink cartridge latch for the black ink cartridge
2 - Ink cartridge latches for the color ink cartridges
NOTE: The ink cartridge areas are color-coded for easy reference. From left to right, the ink cartridges are black, yellow, light cyan, cyan, light magenta, and magenta.
4. Pull the ink cartridge toward you out of its slot to remove it.

5. Remove the new ink cartridge from its packaging.
6. Hold the ink cartridge by the handle and then slide the ink cartridge into the empty slot.
NOTE: Make sure that the ink cartridge is inserted into the slot that has the same shaped icon and color as the ink cartridge. The copper-colored contacts should be facing the printer as the ink cartridge is inserted.

7. Press down on the gray latch until it clicks into place.

8. Repeat steps 3 through 7 for each ink cartridge that needs to be replaced.
NOTE: All six cartridges must be installed. The printer will not work if an ink cartridge is missing.
9. Close the ink cartridge door. Print a test page.
If after doing this it does'nt work, then i will ask you to unplug the printer cable from the computer and uninstall the printer driver/Software completely.
Shut down your computer and restart it.
Re-install the printer driver/software from the start as you did when you bought it.
Good luck

Hi, it sounds that the issue can be caused by a defective ink cartridge that installed or a printhead that can recognize magenta ink cartridge. To identify which causes this issue please try the following:

1. Reseat ink cartridge
2. Replace ink cartridge with a specified ink cartridge for your printer.
3. If above steps wont resolved that issue, please call your printer manufacture and ask for service referral or process warranty options.
