CANON BLACK 225 VS. 226 (not yet linked)
Regarding your question of Canon cartridges, 225 black vs. Canon 226, our answers are provided below:
> The Black 225 cartridge uses a pigment-based ink...this cartridge is primarily intended for
document/text printing. Pigment based inks provide strong longevity / archivability and increase the
black dot gain; this is especially important when printing small black text characters on the page - they
must be rich so they are easily legible to the eye.
>> The Black 226 cartridge uses a dye-based ink formulation specific to photo printing (this is a Photo
Black cartridge). Dye inks provide a greater amount of light to refract through the paper surface/inkjet
medium and effectively increase the amount of reflected color to bounce back to the eye (commonly
referred to as color 'pop', with respect to color appeal to the eyes. This ink formula is very effective for
enhanced photo printing on photo inkjet papers.

IIT Ink Shelf Life (NON FOAM) - HP88/940/932/933/950/951/02
Regarding your inquiry over shelf life (i.e. 3-months of in-operation), the HP940 ink cartridges will be ok
as these tanks do not have foam inside (ink is contained within a heavy duty foil bag)....typically these
can be stored for at least a year without any problems (just keep them out of sunlight). Now, with
respect to the PRINTHEAD (which there are 2 inside your HP OJPRO 8500 printer), they should
automatically 'seal' when the printer is powered down. If you encounter a start-up issue after such a
long period of time, such as missing colors/streaking, then you may need to run a 'PRIME' or
'PRINTHEAD CLEAN' to recover the system.
