I have a Canon Pixma MP620 Printer, and have installed the relevant drivers for Windows XP O/S. I am printing via a USB Cable. When trying to print from Open Office and Wordpad, the paper feeds through the printer as if it is printing, but comes out blank. I have done a Nozzle Check, and that prints all the pastel colour shades, blacks and greys perfectly. Please can you help me to rectify this problem?

I've seen a number of reports like this. I assume that you CAN print from other programs, such as your Internet browser?

If you can't print from ANY program, that's one thing, but if the only programs that aren't printing are WordPad and Notepad (and they print blank pages), the usual cause is that your printer (always a color inkjet of some type) will not print documents that are all black & white, but as long as there is some color in the page, the page prints.

The reason for that is something wrong with the black ink cartridge. Have you recently put in a new black cartridge, and if so, is it not the ink recommended by the printer manufacturer?

Or has the printer been sitting unused for a long time?

Print a test page using the printer's front panel controls. What happens?

Depending on the make and model of the printer, you might need to:
(a) run the printer's print head cleaning routine,
(b) print a test page, perhaps several times,
(c) manually clean the printer's printing head or related parts,
(d) insert a new black ink cartridge of the recommended type.
