Abstract
A method for maintaining a transfer roller in an ink jet printer. In an ink jet printer having a transfer roller on which an image is formed by an ink jet printhead, the printhead is periodically purged to prevent clogging. During purging the ink discharged by the printhead is used to wet the entire surface of the roller to dissolve residual dried ink and the transfer roller is then cleaned with a wipping pad or roller.
