Printer Pixma MX700 will only print in color not black and white?

Try going into Control Panel and click on printers. Normal 0 when the next window comes up, Click on MAINTENANCE, the Properties page will come up and this is where you can do the NOZZLE check/clean and other functions. The NOXXLE is more than likely clogged from lack of use and needs to be cleaned. It might take several times to clean it. Hope this helps. Bud
