Type Wheel Cleaning Brush

A cleaning brush E of the same form as an ink roll B is used in connection with a type wheel A for cleaning the type wheel A.

The figure shows part of a printer having the type wheel A and an ink roll B used for applying ink to the surface of type wheel A.

The ink roll B is typically packaged in a plastic housing C and is held against type wheel A by a spring F. Ink roll B spins freely on its shaft D.

In lieu of the ink roll B in its housing C, a cylindrical cleaning brush E also packaged in a housing C and freely rotatable on a mounting shaft D is interchangeable with ink roll B. When type wheel A needs cleaning, the cartridge for ink roll B is removed; and the cartridge for cleaning brush E is inserted in its place. Type wheel A is then spun, and brush E cleans type wheel A.

In type-wheel printers, there is a buildup of ink and card dust on the type wheel, such as type wheel A, which degrades printing and necessitates messy, time-consuming cleaning. Built-in cleaning systems are often costly and utilize too much room. The cartridge including cleaning brush E interchangeable with the cartridge having ink roll B therein, provides a ready solution for this cleaning problem.
