Hello Everybody,

Is someone good at math. I'm trying to figure out toner coverage.

If a toner cartridge makes 33,000 copies at 6% coverage, how many
copies would it make at only 5% coverage.

Please show me how you got the answer as I'm sure this is going to
come up again.

Thanks!

33,000 * 5 = 165,000/6 = 27,500???

It would make 27,500 - do the rest of your homework yourself;
that's how you will truly learn. Look up percentages in your
reference books.

I thought that, but no its wrong, if you have 33,000 at 6% then at 5% you
would get more not less (27K)

How can you get *more* at a lower percentage? Are you seriously
trying to say you'd get *less* at 50 percent? Duh!

((100 / 6) * 33000) * 0.05

You know, I originally had it written that way, but then changed it. I
originally had an answer of 39,600. But I remembered an algebra teacher
telling me to "cross multiply & divide by the oddball", meaning (ratios)
6/33,000 = 5/x, where x is the answer you're looking for. This gives the
answer of 27,500. That's the way I remember it anyway.

Of course you would... at 6% coverage you get 33,000 pages, so at only 3%
coverage (Half the toner used for each page) you would get 66,000 pages.....
So as the question was if 6% is 33,000 what is 5% coverage, less toner used
more pages, I work it out at 38,500 pages at 5% coverage.

You are mis-interpreting "coverage". Coverage is the percentage
of a page surface that is 'covered' by the ink. Therefore, the higher
the percentage of coverage, the more ink is used, and the less
copies you will get. The industry standard is 5% coverage.

Can't you see that that result is clearly incorrect! You use less tone
per print and thus get fewer prints? Clearly need some ability to reason!
