The cartridge did not last half the claimed number of copies// perhaps sending uninspected cartridges

Hi John,
I am sorry that the cartridge didn't last very long. That sounds disappointing. The advertised estimates of pages are based on a standards set by the industry.
Your usage determines how long a cartridge lasts. High-density prints (such as images and graphs) will use up the cartridge faster.
It is advisable to use the printer's draft mode whenever possible, to help you get more pages. Also most people find the X version of the cartridge to be a better value (if your printer can use those cartridges).
