To be honest when I placed the order for the Xerox 113R00668 OEM black toner cartridge I didn’t know what to expect. I was very happy to discover that everything that was said about the cartridge was all true. From fast delivery to a high yield capacity of 30000 pages. I must say I was truly impressed. I have been able to solve the printing problems of my company and this cartridge has also enabled me to save money that I otherwise would have spent on printing costs. I will definitely be placing another order for this cartridge as soon as this one runs out. This is truly a worthy investment. Thank you!
