A spherical silicone additive is selected and introduced into a contact region between a photoreceptor's anti-curl layer and an electrophotographic system's backer bar, and into a bulk material of the electrophotographic system's spots blade. The additive reduces frictional drag and wear at the contact region between the anti-curl layer and the backer bar and at a contact region between a photoreceptor's outermost surface and the system's spots blade. The reduction of photoreceptor drag and wear at the above contact regions reduces photoreceptor surface irregularities, excessive backer bar wear, excessive spots blade wear, belt ripple and belt contamination. As a result, system drive torque requirements may be minimized, the life of the contacting system components may be extended and system performance may be improved.

Spherical silicone additive for reduced photo receptor drag and wear

An apparatus and printing machine that contain a cleaner brush with long sweeper fibers orientated along the overall width of the brush, and having a greater length than the majority of fibers of the brush to remove the particles that adhere to the cleaner housing and thus, prevent toner droppings.

Cleaning brush having fibers of different lengths

A method, apparatus and printing machine are disclosed that contain a monitoring system that includes a sensor and artificial stress conditions to determine the cleaner brush life. A comparative analysis is performed from the data provided by the monitoring system of a normal cleaning residual toner particle mass and artificial stress conditions cleaning residual toner particle mass to predict brush cleaner life reliably.

Monitoring cleaning performance to predict cleaner life

A multilayer laminated structure comprising an olefin film, preferably a polypropylene film having on a first side, of the olefin film, a highly printable blend of (A) alkylene acrylate copolymer and (B) an interpolymer of an alkyl acrylate, an alkyl methacrylate and an alkyl acrylate acid and a woven or nonwoven reinforcement laminated to a second side of the olefin film. The laminated structure is suitable for envelope stock, packaging film and label stock.

Laminated film and method for making a laminated film

A polymeric film substrate having on at least one surface a prime coating of the type which causes destructive film blocking between contacting layers. This prime coating is top coated with pigmented or non-pigment polyester ink base so as to eliminate the blocking. This top coating is a excellent base for printing inks.

Multilayer film structure

A printable film structure comprising a polymeric film substrate having on at least one surface thereof a prime coating of the type which causes destructive film blocking between contacting layers of such coated films, said prime coating having thereon a continuous copolyester coating consisting essentially of the polyester condensation product of the following monomers or their polyester forming equivalence: (a) about 60 to 75 mole % of terephthalic acid; (b) about 15 to 25 mole % of at least one aliphatic dicarboxylic acid of the formula HOOC(CH.sub.2).sub.n COOH, wherein n ranges from about 1 to 11; (c) greater than from about 6 up to about 15 mole % of at least one sulfomonomer containing an alkali metal sulfonate group attached to a dicarboxylic aromatic nucleus; and (d) stoichiometric quantities of about 100 mole % of at least one copolymerizable aliphatic or cycloalphatic alkylene glycol having from about 2 to 11 carbon atoms.

A multilayer label stock structure comprising a label stock of polypropylene film having on one side thereof a highly printable blend of (A) alkylene acrylate copolymer and (B) an interpolymer of an alkyl acrylate, an alkyl methacrylate and an alkyl acrylate acid.

Label face stock

A composite sheet of a polymeric film form base liner, a cured release coating laminated to at least one side of the base liner, and a coating of at least one high surface energy material (a surfactant/emulsifier) on at least one surface of the base liner.
