Hello Cynthia,

My apologies for this happening to you. The estimates of pages printed are based on standards set for the industry. How a cartridge will perform in your own printer will vary according to several variables, including the surrounding environment.

Toner usage usually determines how long a cartridge lasts, unless it was damaged or defective. High-density prints (such as images and graphs) will run the cartridge out faster.

Here are some things that might help you get savings:
- Most people have found that the X version of the cartridges are a much better value, if your printer can use them.
- Make use of the printer's draft mode whenever possible, to help stretch out the toner

If it appears that poor performance is due to a defect, the return and exchange process is covered, step-by-step, at:
