Paper path sensors and jam detection The paper path sensors detect paper jams as follows: Flipper entry sensor 1 (FLEntry1) and flipper entry sensor (FLEntry):
• paper in the flipper at power on or after clearing a paper jam (when either sensor is activated at power on or after clearing a jam) • paper jammed before entering the flipper (when the printer sends a message that pages are being sent to the stapler/ stacker or stacker, but FLEntry1 is never activated) • paper jammed in the flipper (when FLEntry1 is activated, but FLEntry is not, or when FLEntry1 is never deactivated, or when FLEntry is never deactivated) Flipper exit sensor (FLExit) • paper in the flipper at power on or after clearing a paper jam (when FLExit is activated at power on or after clearing a jam) • paper jammed in the last part of flipping (FLExit never activated) • paper jammed entering the accumulator (FLExit never deactivated) Gear wheel sensor (GWSens)—stapler/stacker only • paper jammed in the accumulator (GWSens never activated) Accumulator exit sensor (ACExit)—stapler/stacker only • paper in the accumulator at power on or after clearing a paper jam (when ACExit is activated at power on or after clearing a jam) • paper jammed in the accumulator (when ACExit is not deactivated after eject) Exit (Exit)—stacker only • paper jammed in the offset module (Exit never activated) EN 3,000-sheet stapler/stacker 213
