Hi i have a brother lc67bk fax printer it won't fax as memory full how do i clear

LC67BK is the Part No. for the Black Cartridge so I presume your Printer Model No. is MFC-420CN as detailed in the heading.

PDF Manual for this model is at the link below which explains about faxing multiple sheets using internal memory.

Power it off!

Then goto start>printers&faxes choose the printer that is printing, in the new box that appears click 'document' then select 'cancel'

Normally if the printer was left on it would continue printing several more pages, as these have already been cached in the memory, switching off the printer for a while clears this.

Are you using fax software? Are you not able to limit the amount of pages to be printed? or at least be able to reject an incoming fax that exceeds a set number of pages?

Problem with my fax Machine MFC 420CN

You can cancel a fax job that is stored and waiting in the memory.
1 For MFC-210C,
press Menu/Set, 2, 5.
For MFC-420CN,
press Menu/Set, 2, 6.
Any jobs that are waiting will appear on the LCD.
2 If you have more than one job waiting, press ▲ or ▼ to select the
job you want to cancel.
Press Menu/Set.
If you only have one job waiting, go to Step 3.
3 Press 1 to cancel.
To cancel another job go to Step 2.
Press 2 to exit without canceling.
4 Press Stop/Exit.

That should do it for clearing faxes you dont need you can also print off all the faxes in the memory and I believe that clears it.

Try scanning at a lower resolution to see if this helps. It could be that the image is too compleax and filling the buffer.
