Hi,

I'm trying to work out how many pages a cartridge would print at 100%
coverage. For 5% coverage it's 310 pages. My brain just cannot seem to get
round this simple calculation. Any help is appreciated and, of course, the
formula that I should use in the future

5% = 1/20, so 310/20 = 15.5 pages at 100%.

That is to say if a given color's cartridge will print 310 pages at 5%
coverage, if you covered the entire page with that color, the cartridge
would last for 15.5 pages.

Many thanks, I did get that figure at one point... honestly.

Thanks again.

In this case;
5/100 x 310 = 15 pages at 100% coverage.

Consider you probably don't print with 100% coverage. All four inks
completely covering the page would be pretty messy!

Hi "geek". Your subject line is interesting, but it's your statement that I
don't understand. I print 100% coverage on my photos...but I'm sure this is
not what you mean. To further the thread, I just got a Canon i560 at Sam's
for \$99.95 (sweet deal considering Worst Buy has them for \$129.99). The
complete set of carts including 2 extra size blacks is \$49.95 (5 carts
total). That's 1/2 the cost the printer which comes with a complete set of
full carts to begin with. So here is what I'm saying...you buy a 3rd party
refill kit, good for about 3-5 refills. Burn through the refill kit then go
out and buy a new printer. You're money ahead. The day is coming when they
will give printers away, you just have to buy the ink. BTW I've printed
about 50 full color 4x6's and the most consumed color (yellow) is only about
1/5 gone. At that rate the retail cost for a print is \$0.20 in ink and what
ever you spend for photo paper. If you refill your cost is only about \$0.02
per print + paper. That is easily competative with Wal-Mart and I print
Butts.
YMMV

To figure out photo ink costs, you simply print a bunch of pages of
photos using full cartridges until they run out, and then figure out how
many photos you get from a set. Add the costs of paper and go from
there.

For photos, it costs me about 25 cents per print. For text, it costs
