Hello Adriatic,

I counted the nozzles of a "check nozzles" pattern. The blacks are 26x16=416
and the colors 3x(10x10)=3x100. But I'm thinking of repeated nozzles in the
"check nozzles" pattern. Because I can't believe that the color it has an
array of 10x10 or similar like 20x5. The black is more "real" with an array
of 26x16 or 13x32 or so.
I asked because I suspect repeated nozzles in the color pattern. 91 (13x7)
or 95 (19x5) or 88 (11x8) is a more "real" array for a hp cartridge. E.g.
the business 1100 has 304 nozzles (may 19x16). I don't know why, hp usually
uses a primary number for the row of the nozzle's array like 19, 13, 11,
etc.
If the color cartridge has 91 or 95 nozzles, there is a reduduncy of 10% or
5% nozzles. It's usefull to know for better classification of refilled
cartridges (may a nozzle pattern shows two nozzles not working, and the
cartridge it has only one not working).

The pattern printed in the check nozzle page reflects the electrical layout,
not the physical layout. Physically the black cartridge has 4x104 nozzles and
the color cartridge has 3x100 nozzles. There are no redundancies in the nozzle
test pattern.

That's a total of only 716 nozzles. Some of the Canons, I believe, have
over 6,000 nozzles. Doesn't this limited number of HP nozzles, by
comparison, hurt their speed and print quality?

In fact Canon has been in trouble. And that is why they pushed that nozzle
game a step futher.

Why?

Simply they are stuck with a designe of their's chartrides whitch have a
seartain maximal ink flow limit. So if you think out and convict a
coustomers that they need some more or aditional inks, then
you have solved for a while that dead end in construction. You spred a
consumation, and this is it.

If you take a look on their's thanks, construction has not changed since
back BJC 6000. And now, how fast are these new Canon printers now?

Now you knew where is a quech.

Thank you for the information.
