An inkjet printer comprises a stationary pagewidth inkjet printhead and a printhead maintenance station. The maintenance station comprises a chassis having a maintenance roller and a transfer roller mounted thereon. An engagement mechanism reciprocally moves the chassis towards and away from the printhead such that a contact surface of the maintenance roller is sealingly engaged with or disengaged from the face. A rotation mechanism rotates the maintenance roller only when the maintenance roller is disengaged from the face, and the transfer roller receives ink from the maintenance roller during rotation of the maintenance roller.

A method of maintaining a printhead comprises the steps of: (i) providing a maintenance roller having a contact surface for sealing engagement with the printhead; (ii) moving the roller into a first position in which the contact surface is sealingly engaged with the printhead; (iii) moving the roller into a second position in which the contact surface is disengaged from said printhead; and (iv) rotating the roller such that the contact surface is conveyed away from the printhead. The maintenance roller does not rotate when the contact surface is sealingly engaged with the printhead.
