Patent ID: 8406673

Claim:
An apparatus for cleaning a rotatable member in an electrophotographic (EP) printer, comprising: a. the rotatable member having a deposition area and a non-deposition area; a toner supply operatively connected to the rotatable member to supply toner to the rotatable member, and a moving receiving member arranged with respect to the rotatable member so that toner is transferred from the deposition area of the rotatable member to the receiving member while the rotatable member rotates; b. a selectively-retractable blade in mechanical contact with the rotatable member so that toner is removed from the deposition area while the rotatable member rotates; c. an artifact sensor for automatically detecting a toner image artifact on the receiver; d. a controller responsive to the artifact sensor for causing the blade to retract when an artifact is detected; and e. a blade cleaner for cleaning the blade while the blade is not in mechanical contact with the rotatable member.
