PLEASE NOTICE THAT due to new programming features in printers to encourage usage of OEM ink cartridges, sometimes, when using remanufactured product, printer might show messages such as "used", "low on ink" or "ready" but with low ink message or no ink level information at all, these are all normal, will not affect printing and actual printing pages yield will be more than OEM ink cartridges.
