A cleaning station for removing particulate material from a moving web in an
electrostatic
printer/copier includes a customer-replaceable web-cleaning cartridge and a support
bracket/backup shoe assembly. The latter serves to support the cleaning cartridge
for movement between an operative position in which web-cleaning components of
the cartridge exert a substantially uniform pressure on the web, and a service
position in which the cartridge is sufficiently spaced from the web to facilitate
replacement and/or service. Preferably, a bracket that supports the cleaning cartridge
is pivotally connected to a backup shoe that is fixed with respect to the web path
and exerts a uniform pressure on the rear surface of the web, opposite that contacted
by the cleaning cartridge. A quick disconnect feature enables the cartridge-supporting
bracket to be de-coupled from the back-up shoe and removed from the instrument.
