I spent years as a wholesale buyer in this industry. On my wife's site
REDACTED - SS she sells both OEM and remans/compatibles so I wrote this for her customers:
Generic toner and ink vs OEM - The Truth About Generic Ink, Toner and Drum Cartridges.
A lot of suppliers use the terms generic, compatible and remanufactured or "reman" too freely and interchangeably. This is wholly inaccurate and you need to know the differences and what you are getting when you purchase these items rather than the OEM.
Q - Should I buy generic and not the genuine OEM? Will it perform the same?
A - It depends on what your printing goals are. If you are printing quality photos to display, a presentation meant to impress or something you are selling we recommend using the genuine OEM brand. These have been fine-tuned to work with your machine and the color and quality will be sharp and consistent. If quality needs to be high but not absolutely perfect or you are doing every day printing, a generic will be more cost effective and you may not notice the difference.
Q - Will a generic void my machine warranty?
A - No. 100% no. It is illegal per the Magnuson Moss Warranty Act to not cover a warranty based on the consumer using a generic cartridge despite what an authorized dealer may tell you. Keep in mind that often the dealer sells the machine and continues to supply the toner (OEM) and perform the service. Buying a generic takes business away from them.
Q - What is meant by generic?
A - We use the term generic here, but not in everyday practice since it provides no true information. A generic is either 100% compatible - meaning it is new in every sense or remanufactured where the original core or shell are used and then reconditioned. A 100% compatible sold in the U.S. market is more likely to be made in China or Mexico where as a remanufactured cartridge is more likely to be "made" in the U.S.A.
Q - Are all compatibles the same?
A - No and Yes. Quality varies greatly between manufacturers and if the materials are of a lower grade or the ink formulation is off you will see it in the results or perhaps a leaking cartridge. Why yes? While there is great disparity between factories, the compatibles you will see in the store or catalog are not actually manufactured by the brand on the box. They are outsourced, sometimes through multiple companies and you don't quite know which company or factory made it. Further, switching suppliers happens often and the cartridge you buy could be different than the time before.
Q - Are all remans the same?
A - Yes and No. See above for "yes". The reason for no, is again quality, parts and the expertise. However a different element is involved due to the fact that some original parts are used. The quality of the product will be determined by which items were replaced how much time was put into cleaning what was kept and which new parts were added. It also matters how many times the original shell has been used. The best remanufacturers use only "virgin" cores - meaning only used once when it was a new OEM and contain mostly new parts especially the drum and cleaning blades/brushes. You also want to make sure a toner or ink cartridge includes the "chip" that was on the original which the printer or copier reads to give technical information like remaining yield.
Q - Should I use a reman vs compatible?
A- Remanufactured will sometimes give better results as it has a closer starting point to the original and does not have to work around as many patent issues. This can be less of an issue for the smaller ink tanks that you often find with Brother and Canon color machines. The compatible is often cheaper. A lot of times only the reman is available from reliable sources as the compatible version has not avoided patent violations. Illegal cartridges are still out there though.
Q - How "Green" is a generic?
A - A compatible offers no recycling at the manufacture point. In addition, since they are made overseas where the factories have less environmental restrictions as compared to the U.S. or an overseas OEM factory, it could be worse. A remanufactured cartridge though does offer earth friendly benefits and is what an environmentally conscious user should look for.
Hope this helps!
