Rene,
Yes, this is normal. Most QTR profiles use LK and K with small amounts of
LC and LM for toning. In my experience with UC inks, the usage is LK most,
K second most and then LC and LM. Depending on the profile used; C, M and Y
are typically not used (unless you are printing sepia and using Y - since
you print sepia, you should see Y usage). But as you note, all are used up
by some amount when you change cartridges and go through cleaning cycles.
You didn't mention what printer you have, but with the 2200 (and my guess
the 2100 as well) if you press the ink button to move the head to the change
cartridge position and when you change the cartridge, don't press the ink
button again. Instead power the printer off and back on and you will not go
through the cleaning cycle. Several on this forum have noted that this will
save ink.
