Cleaning Station for Liquid Ink Development Unit

A precision method is described for establishing, controlling and monitoring cleaning blade load and setting the cleaning blade force against a photoconductor. Also, cleaning structures are capable of cleaning liquid inks at lower blade pressures and with less wear.

A typical prior cleaning blade is shown in Fig. 1. The cleaning blade forces are established through spring blocks 1, one mounted on each end of the cleaning blade. The adjusting technique consists of adjusting the spring compression bolt 2 which compresses spring 3 between bolt 2 and the stud shoulder 4 of stud 5, thereby transmitting the spring load through the stud to the blade holder 6. The load on each side of the blade is difficult to determine and the settings are not repeatable.

A precision method of setting the cleaning blade load is desired in order to determine the cleaning blade loads required for various types of cleaning blades, for various types of inks, for different photoconductors, and to keep an accurate record of the loads so that they can be duplicated.

The strain gauge spring block arrangement of Fig. 2 is capable of setting a precise load, incrementally adjusting the load, monitoring and recording the load, and repeating the same load as desired. Such an arrangement reduces photoconductor wear and cleaning blade wear due to the ability of setting up the minimum cleaning blade load required, extends photoconductor life due to accur...
