International Classification:

G01D 1500

US Classification:

3461531

Abstract:

The print head of an electrographic printer is cleaned electrostatically. The printhead has a number of electrodes in an electrode array, which cooperate with a dielectric belt. Periodically, printing with the printer is interrupted (e. g. after every 100 pages of printing, or about every minute), and then substantially all of the electrodes are energized at the same time for a time period sufficient to effect burning off of contaminants from the electrodes (e. g. about the time it takes to print four pages, or about 3 seconds). A host computer controls the operation of the printer components. The printer developer unit may be moved away from the dielectric belt prior to the energization of all of the electrodes to effect cleaning.

Abstract:

An accent color printer for printing on a continuous web of material has spaced apart drums, and a flexible continuous belt positioned around the drums. The belt defines a transport path having an arcuate portion at one of the drums. A platen cooperates with the belt to define a curvilinear print region for said transport path. An input module positions a continuous web onto the moving belt. Print heads positioned adjacent the belt print accent colors onto the web at the print region. An outfeed module removes the web from the belt at arcuate portion of the transport path and tensions the removed web whereby the web forms a capstan wrap with the belt at the arcuate portion of the transport path. The capstan wrap results in the tension in the web at the printer region being increased from the tension in the web removed from the belt.
