Digital BW, The Print

Hello Jeremy,

(total 24 carts)

Thanks for the good report.  So if you have used 24 carts to make 298
letter size prints, then you're getting apprx 12.4 prints per cart. 
At $20/cart it comes to about $1.61 per letter size print.  With Atlex
prices here in the US ($11.20+shipping, so about $12.00 ea), 12.4
letter size prints per cart would be about $0.97 per print.

Im curious about ink usage in color vs BW.  You said you're about 4:1
color:BW.  I've rearranged your cart list in order of most used and
see that LM and LK top the list.

>.LM - 6
>.LK - 5
>..Y - 3
>.LC - 3
>LLK - 2
>..C - 2
>..M - 2
>.MK - 1

I haven't counted my prints, but I have kept all my used carts (also
just did a survey of the Status Monitor) and have totaled how much ink
I've used in 5 months (got the printer in middle of August).  All my
printing is in ABW, almost all of it at fairly neutral settings. 
Here's the result:

LLK - 2.25
.LM - 2.00
.LK - 1.90
.LC - 1.75
.MK - 1.70
..Y - 1.10
..C - 1.00
..M - 0.80

Obviously the arrangement is different, is it safe to assume that the
over all quantity per print would be similar?

Clayton
