When removing the ink cartridges it is advisable to rest the in the same position as you find them in the printer, like storing books in a book shelf.
Do not leave these out longer than is necessary and after you reinsert them DO run the print head cleaning and nozzle check utility as advised.
In response to the question on how best to store your ink cartridges so they do not dry up on you: Place these in a zip lock style bag to keep as much air from getting to them as possible.
Even after storing in this manner or leaving them out in the open while you clean your printer. It is advisable to gently press an alcohol soaked paper towel against the ink jet surface. Just please do this as gently as you can until ink is flowing freely from the holes.
Once your printer is assembled again, as stated in the Tip itself, run the deep head cleaning routine several times. Your printer may or may not use the same terms to infer a deep head cleaning, this is typical from one model series to another. The point is to run the head cleaning utility several times to ensure your heads are not clogged up at all.

AToe,
Some Canon Printer Models are extremely difficult to remove the cover plates fo the printer simply to access the waste pads.
Anyone with a Complex Canon Printer with difficult to access waste pads so you can clean them should visit Neil Slade's web site. Mr Slade's web site will give you thorough and accurate step by step instructions to safely disassemble your Canon printer so you can access the print heads and the waste pads.
Remember, this is for those few complicated Canon printers that will not allow you to reach and grab the pads as I instructed in my How To.

AToe - Your instructions leave a whole lot to be desired when compared to Neil's work at his web site. I encourage any Canon Printer owner to visit and bookmark Neil's web site.
Sorry - my earlier comment is wrong. There was so much muck in that well area that I couldn't see the sponges clearly. To the right - what looked like three small sponges - was actually one 1-inch wide sponge handling the black, magenta and yellow cartridges. Later, after clearing away some of the gunk, I found a 1/2-inch wide sponge at the left side of the well that handles the blue cartridge. Cleaned them both, together with the cartridges and printheads. Now a bit better, but still have other print problems, especially black lines suddenly printing on top of each other. Time for a new machine, but I don't like the new HP J6480, L7680 or L7780. Too many negative reviews, and they look and feel flimsy in the store, whereas the d135 was pretty solid. WHAT WOULD YOU RECOMMEND AS A REPLACEMENT FOR OUR D135? Doesn't have to be HP. Need same functions. Thanks. glnz
