Paper Jam DetectionThe OKIFAX4550/OKIFAX4550 ISDN monitors the paper status when the power supply ison and during printing. In the following cases, the OKIFAX4550/OKIFAX4550 ISDNinterrupts the printing process as a paper jam. Printing can be recovered by opening thecover, removing the jammed paper, and closing the cover.
