I think the calc's are off for the R2880 which has a 11.4 mL cart.

7 * .386   =  2.7 mL

if the R2880 cart is 11.4mL then 2.7 / 11.4  =  0.24   or 24% !

This means that if another cartridge has less than about 1/4 of ink left, then you should change it too !

BUt John, your calcs are based on a different printer and the mass of the ink used.

I looked at the before and after images of the ink level indicator on my printer (the R1900 not the R2880). I estimated that about 1/32 of each ink cart drops during an ink cart change.

therefore:

1/32   *   7    =   0.22   or 22% !

So again this means that if an ink cart has about 1/4  to 1/5 of ink remaining, then you should also swap that cart. Thats for the R1900. Perhaps my newer R2880 uses less. I will have to wait to see when it time to change an empty cart and repeat my estimations again.

So JOhn I think that you're estimate of 1/8 of a cart may be accurate for the R2500, but from my observations and calcs it is being too generous.

When a single cart is replaced, do the larger printers that use lines from the carts to the print head (3800 and larger, I guess) do a charge cycle or whatever for each cartridge or just for the one that's being replaced?

So far as i know, this happens with all printers. some  are saying that this is not an issue with the larger printers with much larger ink cartridges. well , you still loose ink from all carts during an ink cartridge change except that you  just dont have to do this so often so that is where u save..
