发明名称 Friction paper-feed method and apparatus capable of preventing paper-feed failure caused by slippage
摘要 A friction paper-feed apparatus and method used in an information processing apparatus such as a facsimile apparatus prevents a paper-feed failure caused by a slippage produced at a contact region between a friction paper-feed roller and a sheet of paper. The friction paper-feed roller is driven with at least one of a drive operation having a relatively long time length, another drive operation having a relatively short time length, or both of the relatively long time length and the relatively short time length. The friction paper-feed roller is controlled to execute a stop operation after each of the drive operations. The stop operation is also executed after repeating a driver operation for a number times so as to terminate an execution of paper transferring operation and to prevent a paper-feed failure.
