Abstract
An imaging drum maintenance assembly that includes an oil applicator device, and an elastomeric metering blade spaced from the applicator roller and having a bulk resistivity that is less than about 500,000 ohm*meter.
Claims20
An imaging drum maintenance assembly comprising:
- an oil applicator device;
- an elastomeric conductive metering blade spaced from the oil applicator device and having a bulk resistivity that is less than about 500,000 ohm*meter and;
- a conductive bracket composed of at least one serrated edge at which the metering blade is attached.
An imaging drum maintenance assembly comprising:
- an oil applicator device;
- a conductive elastomeric metering blade having a bulk resistivity that is less than about 150,000 ohm*meter, spaced and not in contact with a non-conductive applicator roller having a bulk resistivity greater than about 1×1011 ohm*meter;
- and
- a bracket comprised of a serrated edge of a series of adjacent equidistantly spaced jagged points arranged in a linear row and attached to the metering blade.

An imaging drum maintenance assembly comprising:
- an oil applicator device;
- a conductive grounded, consumable, elastomeric metering blade spaced from so as not to be in contact with the oil applicator device and having a bulk resistivity that is less than about 500,000 ohm*meter;
- a conductive bracket for supporting the elastomeric metering blade, the bracket comprised of at least one series of adjacent, equidistantly spaced lagged points arranged in a linear row;
- and
- a print head for dispersing ink to the imaging drum prior to any action of the oil applicator device and the metering blade.
