Abstract

Elektrofotografischer Drucker mit einem verbesserten, flexiblen Kettenschutz (50), der zum Schutz der Tonergehäuse-Antriebskette gegen Verschmutzung durch Tonerstaub angeordnet ist. Der elektrofotografische Drucker kann einen starren Kettenschutz (68) umfassen, der benachbart zu dem flexiblen Kettenschutz (50) angeordnet ist, derart, dass der flexible Kettenschutz (50) und der starre Kettenschutz (68) einander überlagern.

Figure imgaf001
An electrophotographic printer having an improved flexible chain guard (50) disposed to protect the toner cartridge drive chain from toner dust contamination. The electrophotographic printer may include a rigid chain guard (68) disposed adjacent to the flexible chain guard (50) such that the flexible chain guard (50) and the rigid chain guard (68) overlap one another.
