Cleaning structure and method for friction roll feeders

摘要

With a cleaning system/method, a user places a printing device in a cleaning mode, inserts a cleaning apparatus that includes a cleaning sheet into a paper supply tray of the printing device, and executes a cleaning operation on the printing device. With the system, a set of instructions is stored on a machine-readable medium. The set of instructions causes the printing device to execute a cleaning operation on a feed nip of the printing device. The cleaning sheet cleans the feed roller and the retard roller when it is positioned within the feed nip during the cleaning operation. The set of instructions cause the printing device to move the cleaning sheet into the feed nip and to rotate the feed roller and the retard roller for a predetermined time period, when the printing device is placed into a cleaning mode.
