摘要：
The invention relates to an apparatus for detecting sheet misfeed from a tray having at least two sheets whose thickness differs from each other. The thickness of each sheet is detected as it enters into the tray and that value is placed in memory. The thickness of each sheet is detected as it leaves the tray and that value of each sheet is compared to the thickness value in memory for the same sheet when it entered into the tray. If the values match, then only one sheet has been fed from the tray. If the thickness value of the sheet as it leaves the tray is more that the thickness value in memory, then that indicates that more than one sheet has left the tray and a signal is produced which results in the sheet feed system being shut down to enable an operator to correct the situation.
