Brother MFC-240C My fax machine has been working. I went away for a while, came back and replaced all the ink cartridges with the correct brother ones. Now the machine won't do ANYTHING and the little window says "close cover." I have checked and re-checked and cannot find anything open. Oh- It won't turn off either

It may be a memory issue.

Unplug the machine from the power.

Remove all the ink cartridges

Replug the machine and reinstall the ink cartridges

Make sure there is ink in all cartridges and unplug the machine. Plug it back in while you hold the stop key and it should clear the error.

Drum for Brother MFC-6800 All in One Machine
You can expect it to print 12,000 Page Yield
Whats the difference between a DRUM and a TONER Cartridge? The toner cartridge is a cartridge holding the toner (ink). The drum does the work to transfer the ink to the paper. You will need to replace the drum every 5-6 toner cartridges you use.

Is it an ORIGINAL BROTHER cartridge ? ?

OR

A cheaper version ? ?

media refers to the paper to be printed on. check that the guides are set correctly and there is nothing blocking the paper sensor in the paper tray.

Somethings that have worked for some Brother owners to get cartridges recognised.

1. With your MFC powered up, open it up and remove the cartridge you are having a problem with, then close the MFC, leaving it powered up. It should report that there is no cartridge in the machine.

Still with the MFC powered up, open it up and reinsert the ink cartridge, then close the MFC. It should either ask if you have replaced a cartridge or go into its cleaning mode.

Answer "yes" to "have you replaced cartridge?" and it should either "print" or "clean" and then "print".


2. The cartridge holder in the printer has an "electronic eye" (light sensor) of some type for each cartridge.
Some users have found that putting either permanent marker/sharpie/black PVC tape either on the area of the ink cartridge that goes near the sensor or alternatively putting tape over the sensor itself allows printing to occur.
The problem with this method is that the printer will no longer recognise near-empty cartridges and so will not warn you to replace them and so the print head may be damaged. This is said to work on LC57 icartridges used with the following models: DCP-330C, DCP-350C, DCP-540CN, DCP-560CN, FAX-2480C, MFC-240C, MFC-440CN, MFC-465CN, MFC-665CW, MFC-685CW, MFC-885CW, MFC-3360C, MFC-5460CN, MFC-5860CN.

I'll bet you're using cheap generic ink, after having used real Brother ink cartridges. It sees and it knows the ink is generic (apparently by measuring the electrical resistance of the ink). I'm in the midst of the same issue and am going to try using real Brother cartridges to see if the problem goes away.

IssueAn 0xc18xxxxx or 0xc19xxxxx ink system error code displays on the front panel. The printer cannot copy, receive faxes, or print. Solution
Press the On button to turn the printer off. 
Unplug the power cord from the back of the printer.
Remove all the ink cartridges.
Wait two minutes.
Plug the power cord into the back of the printer.
Press the On button to turn the printer on. 
Install the ink cartridges when prompted.
If the error code does not display, the issue is resolved.
If the 0xc18xxxxx or 0xc19xxxxx ink system error code displays on the front panel, service the printer.

you will probably have to have all cartridges working.

If you only want to print in b/w and do not use the color ones there is a workaround.

Please notice that you will destroy the C/Y/M part of the print head because the ph needs the ink to prevent a dryout!!!

Simply stick some adhesive tape around the window in the middle between the ink-outlet and the valve. The flag inside signals the printer the inklevel (and also the cartridge being installed).
