Abstract

Blade cleaning is well known in the xerographic arts, however current architectural configurations pose potential problems for blade type cleaners. A specific configuration is the 3 o'clock position blade cleaner, see FIG 1 (End View). The cleaning blade in doctor mode is assisted by a disturber brush. As residual toner is removed from the photoreceptor a small pile of toner may collect at the blade tip. As toner builds up it then falls under gravity into a waste container. A potential failure mode for this configuration occurs when the blade cleaner is cammed out of position, and the collected toner on the blade tip falls down onto a charge corotron.

METHOD FOR REMOVING RESIDUAL TONER FROM 3 O'CLOCK CLEANER BLADE(Cont'd)

Blade cleaning is well known in the xerographic arts, however current architectural configurations pose potential problems for blade type cleaners. A specific configuration is the 3 o'clock position blade cleaner, see FIG 1 (End View). The cleaning blade in doctor mode is assisted by a disturber brush. As residual toner is removed from the photoreceptor a small pile of toner may collect at the blade tip. As toner builds up it then falls under gravity into a waste container. A potential failure mode for this configuration occurs when the blade cleaner is cammed out of position, and the collected toner on the blade tip falls down onto a charge corotron.

A solution to the failure mode problem is to use a hybrid disturber brush configuration, see FIG 2 (Side View). As the disturber brush rotates, a hel...
