Question about Brother MFC-640CW All-In-One InkJet Printer

2 Answers

Brother MFC-640CW Was working fine in every way. Today I went to use it and it won't power on. Did all the needed test of electric outlets and the outlet is fine. Hold the on/off button down and the LCD screen won't light up at all. Is there some type of fuse in this unit or is there something else that I can check

Try pulling the cord from the back of the printer and re-inserting it.

Brother MFC-640CW All-In-One yellow not printing

if your print head is removable (the thing your ink cartridge clips into) remove it and clean it out with asorbic alcohol on both the print face and the ink inlet area- If your yellow has been empty for a while before you bought a new cartridge, it is possible that ink has dried in the ink channels of the print head and this is almost impossible to repair and you would be better off buying a new print head- Also if you have a fairly new printer you can contact the manufacturer about your issue and they may or may not send you one for free- My KodaK AIO had the same issue and Kodak replaced the print head for free all I had to do was take the time to call them

MFC 640CW not refilling with new ink cart.

Unplug printer from power. Wait a minute. Take all carts out. Plug machine to power. mfc demands carts. Reinsert carts (have a look if they all filled with ink!!). If asked press 2 (No change) despite you use a new cart press 1 Yes cart changed.

Should work!
