Abstract
A method of maintaining a printhead in an operable condition is provided. The method comprises the steps of: (i) providing a chassis having mounted thereon: a maintenance roller having an elastically deformable contact surface and an ink removal system for removing ink from the maintenance roller; (ii) moving the chassis towards the printhead such that the contact surface is sealingly engaged with an ink ejection face thereof; (iii) moving the chassis away from said printhead such that the contact surface is disengaged from the face; and (iv) rotating the maintenance roller such that ink is removed from the contact surface by the ink removal system.
