Faxes I keep getting an error message: faxes in memory. Change empty cartridge and try printing again. However, both my color and my black cartridge are brand new.

on ours the cartridges click twice to be fully seated..there are 4 cartridges in this one.. if one is not all the way down, it will error..in extreme cases if all the cartridges are in place..unplug the unit and reboot it..

Generally the "received in memory" message is a result of the machines inability to print. I.E. It received a fax, attempted to print it, failed, and then stored it in memory to print once the issue has been corrected.

The Prepare Black Toner error is likely directly related. If the toner cartridge is empty, inserted incorrectly, or damaged it could be causing this error. Try reseating the cartridge by removing and reinserting. If that doesn't clear the error try replacing it with a new Canon branded cartridge.

As soon as you correct the printing issue the stored faxes will print.

Specifically on the Magicolor 5430DL you can print when a cartridge is empty, but this is disabled by default. To enable printing even with a toner cartridge empty.Press the Menu Button, then press the right button until the ENGINE menu appears and press the select button.Next press the right button until TONER appears and press SelectOnce in the Toner Menu the first option should be "EMPTY" if not press the right button until you see "EMPTY" and press Select.There are two options, the default is "STOP" pressing the right button once should change from STOP to CONTINUE.While the display reads "CONTINUE" press Select.You should see the message "CONTINUE is selected"You can now print even when one or more cartridges are empty. However, the lack of the cartridge's color will be noticed in any print jobs calling for that color... (Obviously)

it is problem printer cartridge change it then solve it

Hi,
I would like to inform you that there is no way to print with black cartridge alone. You need to install two cartridges to wok the printer. So I recommend you to install color cartridge and change the settings to print in black only.

Actually there is no solution to this "problem" nearly for all Inkjet machines.
The reason is that Printers are Dummy Receivers, meaning that they can not process the print file, sent to them by any source. They are programed to just print the file without "asking questions".
The Manufactures now, of Inkjet machines, in order to avoid the possibility of printing something with a certain colour missing, they have just programmed their machines NOT TO PRINT ANYTHING whenever ANY colour is empty.
So, dont bother trying to print making all kind of adjustments and change settings and get a new cartidge :)

Sadly in a word, 'No'.

Here is the exact answer from Brother:

Your Brother machine is designed to stop ALL printing operations
(printing from the pc, printing received faxes and printing copies or reports) when any of the ink cartridges are empty. This is to ensure the life of the print head and maintain premium print quality. If the unit were to continue printing, print jobs and cleaning cycles would suction air from the dry cartridge and damage the printhead. Even if you print in black only or change the print settings to MONO or GRAYSCALE to avoid printing in color, the programmed cleaning cycles would still suction the dry cartridge, because they are programmed to clean ALL the ink nozzles.

The only way to continue printing is to replace the empty ink cartridge or cartridges.

While memory is available, black and white faxes will continue to be received into memory. If a color fax is being received, the Brother machines HANDSHAKE will request the fax be sent as black and white fax.

All faxes received into memory will automatically print once the ink cartridge is replaced.

NOTE: Brother strongly recommends that customers do not use generic ink or refill their Brother ink cartridges. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability since the ink formulation in genuine Brother ink cartridges prevent smearing and clogging of the print head. The Brother limited warranty does not apply to any problem that was caused by the use of unauthorized third party ink and/or cartridges.

The Brother machine will not print if the message "Toner Empty X" ( X =C for Cyan, M for Magenta, Y for Yellow and K for Black) is displayed on the LCD. The empty toner(s) must be replaced in order to continue printing. Incoming faxes will be stored in the memory until the toner(s) is replaced.

=) SOLUTION!!! To print from memory, simply press the "FAX button on the front panel.
Then, press the "MENU" button. "1. Fax Settings" will appear in the display. Press the
"right" arrow key once so that you get "Memory Reference" to appear on the screen.
Press the "OK" button once. It will display "Print List", but you want to "Print Document",
so press the "right" arrow key until you get to "Print Document" and press "OK."
Once you are there, press "OK" again and the message "Print 1st page only?" It displays a YES and NO, so hit the left or right arrow key to choose. If you want to print the entire document,
choose NO and press "OK" Your document will print out!!! =)
