Black printing problem IP3600

[Alexyxx]

I have been having a problem with printing ordinary black typescript with a Canon Pixma IP3600, but only since upgrading OS from WindowsXP to Windows7 a few weeks back, and only with the PG fat Black ink.

Printing a page goes from full good black to fading out to no print at all, in the course of printing about two pages. No grid on nozzle test, but after a deep clean all is well again, lovely black printing for a page or two. Then it all happens again!

Never had anything like this before in several years. Could this be a software problem? maybe it is failing to do routine cleaning? Anyone has an idea how to solve it?

The fat black inks are pigment inks. Maybe try reoving the cartridge and give it a good shaking.

No, shaking does not solve the problem, nor changing the cartridge.  Howevwer, if I do a "normal" clean of the fat black cartridge nozzles every day, that seems to work. Maybe  that SHOULD happen automatically?  But maybe when I upgraded to Windows 7 the automatic cleaning of the fat black  cartridge nozzles stopped working?  Any comments anyone? Any possible fix?
