re: ABC’s of ISO Toner and Ink Yield Standards

Problem of both standards is, that not many of the customers are printing in the way the new (and old) standards assume.

So, yes, you can compare ink printers of different manufacturers with each other when it comes to continously printing.

But the average customer prints in batches and there you have the printer's self cleaning process kicking in. The yield therefore also depends on how efficient the printer's self cleaning process is and how often it is performed by the printer. Unfortunately those characteristics vary heavily from manufacturer to manufacturer and even from printer to printer.

So, no, even with the new standards you can't compare the printers with each other when it comes to real life printing duties.

Yes, if you get 3500 pages with 5% coverage, you can assume 1750 at 10%. However, the ISO standards do not talk about coverage, but rather focus on real world pages. If you look closely now at OEM claims, most are now following ISO giving you an apples to apples comparision for the first time!

Is the relationship of yield and coverage linear? Will you get 7000 prints at 2.5% as well as 3500 at 5%, 1750 at 10%?

Do OEMs put limits on yields less than 5% so you get say only 4200 prints and not 7000? Is this a function of the cost of the printer?

We still use your IPP Expert Test Suite on a daily basis. We are just waiting on an update to be able to test on Windows XP or newer and the new IPP 2.0/2.1 specs.
