On a Lexmark inkjet printer, the print head is part of the cartridge. By 'remanufactured' they mean that they filled an old Lexmark cartridge with ink and (possibly) cleaned the head as only Lexmark actually make Lexmark cartridges.
As you have two cartridges failing it means that you have two bad cartridges which is sometimes the case with 'remanufactured' cartridges.
