General FAQ's for Inkjets and Toners


Why didn't my cartridge print the full amount of pages?

Why was the yield lower than what was quoted online? Customers often worry about the yield of their cartridges. They often mistakenly try to track yield by time. The amount of time it takes for a cartridge to go empty is a bad indicator of yield. The cited yield for ink and toner cartridges is given at 5% coverage. This is usually not a lot of print on a page. Typically only a short memo is at 5% coverage. If you are printing letters, using legal size paper, printing photos, web pages or doing any kind of graphics your coverage will vary greatly. This will cause the yield to drop greatly.


There are two ways to properly check for yield. First is to utilize any page count your printer has. Refer the user's manual for instructions. The other way is to count reams or boxes of paper you have used with each cartridge. Both of these methods will tell you how many pages per cartridge you are using. 


Both methods give you a raw number. You should also take into account your typical print coverage. If you only do memos then you should reach the manufacturer's stated yield specifications. If you write full-page letters or print graphics your yield will be considerably less. When printing text and full page graphics a 4000 page yield cartridge will run out of toner in around 800 pages. If you have a color toner printer that uses all four-color cartridges (black, cyan, magenta, and yellow) and you turn it off (power it off) every night and weekend you are also using additional toner. Every time you turn your printer back on (power it up) it must do what is called a "Color Calibration". This could waste as much toner as would be used for 2 pages of print or in other words, up to 12 pages a week. Always leave your toner printer turned on (it will go into a sleep mode to save power) and only turn it off when necessary.


Will my OEM printer warranty be voided if I use compatible, remanufactured, or refill my cartridges?

The answer is NO! The following is a partial quote from the Magnuson-Moss Warranty Improvement Act, which protects your rights and your warranty.

United States Code Annotated
Title 15 Commerce and Trade
Chapter 50 Consumer Product Warranties
15 Section 2032

... (c) No warranter of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name; except that the prohibition of this subsection be waived by the commission if:

1) The warranter satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and

2) the Commission finds that such a waiver is in the public interest.

More simply put, this means that your printer warranty cannot be voided just because you choose to use compatible products unless the manufacturer can prove that the compatible product caused direct damage to your printer. In cases such as this, the manufacturer may choose not to repair your printer but your warranty would remain in effect for all other warranty issues.


Do you buy back empty cartridges?

Yes, we currently accept all empty OEM and aftermarket ink cartridges, but will only pay for certain OEM ink and/or toner cartridges. We either pass them on to our recycling partners or we remanufacture some of the OEM ones. It helps keeps our costs down and retail prices low. But we will not take every type of OEM toner cartridge or any non-OEM toner cartridges, so please go to our  Recycle Program page for complete details.
