Frequently Asked Questions

I receive a defective Lexmark T640N toner cartridge. Will I get a free replacement?

Yes. All our remanufactured Lexmark toner cartridges are covered by a 1-year warranty. So if ever you receive a defective cartridge, kindly inform us so we can send you a replacement along with a prepaid shipping label to return the defective product to us.

What are your delivery fees?

Our delivery fees vary. For orders $30 and up and shipping to the continental US, shipping is free. While US contiguous orders below $30 require $3.95 for shipping. For orders shipping to the non-contiguous US, the shipping fee is $24.99.

Why did the toner cartridge not print the estimated number of pages?

The number of pages that the toner cartridge prints depends on what types of documents you print. The stated yield for the toner cartridge is based on 5% coverage. If your printed pages have more than 5% coverage (web pages and graphics), you get less than the estimated number of pages.
