ABSTRACT:
An apparatus for efficiently cleaning a platen roller of a printer. A cleaning unit is attached to a main unit in place of a removal unit for an intermediate transfer sheet. A cam is turned by means of turning an arm UP/DOWN lever, and the arm is turned from an UP position to a DOWN position by means of the cam, to thus bring a cleaning pad on a leading end of the arm into contact with a platen roller and perform cleaning operation. When an operation mode is set to a cleaning mode and when attachment of the cleaning unit UC is detected, the platen roller is rotated, thereby allowing cleaning operation.
