  • Inkjet printer cartridge adapted for enhanced cleaning thereof and method of assembling the printer cartridge
    Patent number: 6585348
    Abstract: An inkjet printer cartridge adapted for enhanced cleaning thereof, and method of assembling the printer cartridge. An inkjet printer cartridge comprises a cartridge body defining a chamber therein. A substrate is coupled to the cartridge body and has a hole therethrough in communication with the chamber. An orifice plate is coupled to the substrate and has an orifice therethrough aligned with the hole. A platform is coupled to the substrate and surrounds the orifice plate. The platform defines a relatively smooth surface thereon having a predetermined surface roughness for sealably engaging a cap belonging to a print head cleaning service station movable into engagement with the printer cartridge. The surface of the platform may have a surface roughness of between approximately 0.5 microinches and approximately 2.0 microinches. Moreover, the surface of the platform is also level for sealably engaging the cap.
