A method for controlled installation of a brush filament population on a shaft for making a toner adder brush roller includes applying a layer of adhesive over a surface of a roller shaft, applying a template over at least a portion of the shaft surface, and flocking a multiplicity of filaments on the shaft surface to provide a brush on the roller shaft having a filament population controlled by the application of the template. The method also includes removing the template from the shaft surface after flocking the multiplicity of filaments such that a set of filaments less than the multiplicity of filaments is removed with the template. The method further includes flocking additional filaments on the portion of the shaft surface after removing the template from the portion of the shaft surface, the additional filaments differs from said previously flocked filaments in one of material, length, denier, or combinations of the foregoing.

Blockage of the holes in an ink jet nozzle is greatly reduced by immersing the polyether polyurethane foam from the ink jet cartridge in cold water for a period of at least six hours.

Process for reducing blockage in nozzle holes for ink jet printing

In a clean room cups (70) are applied to the standpipe (28) of an unfilled inkjet cartridge. A sealing cup (80) is applied to the ink outlet (46, 48, 50) of the cartridge. Inert gas is forced back and forth between the cups and expelled into the clean room through a filter. Such cleaning removes particles, which significantly improves reliability of the filled cartridge.
