2 | Separation Sensor |
3 | Exit Sensor |
4 | Registration Sensor |
5 | Skew Correction Sensor |
6 | Double-Feed Detection Sensors (Lower: emitter, Upper: receiver) (Option) |
The six sensors listed above are used in jam detection. The readings of their output are used as described in the table below.
Code | Display | Jam Name | Jam Description |
|---|---|---|---|
13 | P | Separation sensor late jam | Leading edge did not arrive after paper feed motor started and operated long enough for 224 mm of feed. |
14 | P | Skew sensor late jam | Leading edge not detected within time for 46 mm of feed after detection by separation sensor. |
15 | P | Skew sensor late jam | Leading edge not detected after pull out started (grip motor) and enough time elapsed for 172 mm of feed. |
16 | P | Registration sensor late jam | Leading edge not detected after skew correction sensor detected leading edge and enough time elapsed for 96 mm of feed. |
17 | P | Exit sensor late jam | Leading edge not detected after registration sensor detected leading edge and enough time had elapsed for 130 mm of feed. |
63 | P | Separation sensor lag jam | This table shows how the amount of feed is calculated when the leading edge of the original is not detected after grip motor starts to pull out original. Standard value: -35.3)×1.5 However, if the operator changes the original length setting, the new specified value will be taken as standard. |
64 | P | Skew sensor lag jam | Trailing edge was not detected after separation sensor has detected trailing edge and enough time had elapsed for 46 mm of feed. |
65 | P | Skew sensor lag jam | Trailing edge not detected after relay motor stopped and enough time had elapsed for 82 mm of feed. |
66 | P | Registration sensor lag jam | Trailing edge not detected after skew correction sensor detected trailing edge and enough time had elapsed for 93 mm of feed. |
67 | P | Exit sensor lag jam | Trailing edge not detected after registration sensor detected trailing edge and enough time has elapsed for 130 mm of feed. |
99 | P | Double-feed jam*1 | Double-feed sensor pair (ultrasound) detected a single weaker than that expected for the original is use and signaled double-feed. |
*1 | Detected by the double-feed sensors after this option is installed. | ||
Abnormality Detection
Errors that occur twice in succession are treated as jams, three times in succession as SC errors.
