Abstract
A drum maintenance system for use in an imaging device includes a reservoir having a supply of release agent. An applicator is configured to receive release agent from the reservoir and to apply the release agent to an imaging surface of an imaging device. A metering blade is positioned to meter the release agent on the imaging surface applied by the applicator. The metering blade is arranged in doctor mode with respect to the imaging surface and includes a tip positioned adjacent the imaging surface. The tip has a square portion positioned proximate the imaging surface and a beveled portion opposite the imaging surface.

A drum maintenance system for use in an imaging device, the system comprising:
- a reservoir including a supply of release agent;
- an applicator configured to receive release agent from the reservoir and to apply the release agent to an imaging surface of an imaging device;
- and
- a metering blade positioned to meter the release agent on the intermediate imaging surface applied by the applicator, the metering blade being arranged in doctor mode with respect to a process direction of the imaging surface and including a tip positioned adjacent the imaging surface, the tip having a square portion positioned proximate the imaging surface and a beveled portion opposite the imaging surface.
A phase change ink imaging device comprising:
- an imaging surface;
- at least one printhead configured to emit melted phase change ink onto the imaging surface;
- and
- a drum maintenance unit including:
- a reservoir including a supply of release agent;
- an applicator configured to receive release agent from the reservoir and to apply the release agent to the imaging surface;
- and
- a metering blade positioned to meter the release agent on the imaging surface applied by the applicator, the metering blade being arranged in doctor mode with respect to a process direction of the imaging surface and including a tip positioned adjacent the imaging surface, the tip having a square portion positioned proximate the imaging surface and a beveled portion opposite the imaging surface.
A customer replaceable unit (CRU) comprising:
- a reservoir including a supply of release agent;
- an applicator configured to receive release agent from the reservoir and to apply the release agent onto a surface;
- and
- a metering blade positioned to meter the release agent on the surface applied by the applicator, the metering blade being arranged in doctor mode with respect to a process direction of the surface and including a tip positioned adjacent the surface, the tip having a square portion positioned proximate the surface and a beveled portion opposite the surface.
