Document jams are detected bythe front and the back registration sensors.The front registration sensor and the backregistration sensor are located at the front andback of the registration roller, respectively. Thefront registration sensors are divided into the leftsensor (L) and the right sensor (R), and aremounted on the front registration sensor PCB.The back registration sensor is mounted on theback registration sensor PCB.1) Early reach jam (P01)The front edge of the following document wasdetected after the end of the proceedingdocument is detected before the motorfinishes driving the specified length.2) Residual jam (P02)The end of the document is not detected eventhough the document has been fed for aspecific length after the front edge wasdetected.3) Fast feed jam (P03)The end of the document is detected beforethe document has been fed for a specificlength after the front edge was detected.When the machine is powered on or theupper unit is opened/closed with a document leftin the machine, a removal jam (P00) occurs.8. Special Feed ModeThis unit also supports a mechanical feedmode to check the feed condition without using apersonal computer.This mode should not be available to theusers.The mechanical feed mode can be activatedby pressing the keys on the operation panel, asfollows:a. Turn on the power switch with the startkey pressed.b. Continue pressing the start key for aboutone second.c. Press the stop key.If the start key is pressed while in themechanical feed mode, with documents in thedocument tray, the machine will feed thedocuments at a feed speed determined by theSCSI ID set on the DIP switch located at thecomputer connection. Images are not scanned atthis time.When specifying the feed speed is notrequired, it is possible to check the feeding stateusing the "Count Only mode".Feed speed 1 2 3ID0 Black/white200DPIOFF OFF OFFID1 Black/white300DPION OFF OFFID2 Black/white400DPIOFF ON OFFID3 Black/white600DPION ON OFFID4 Color 200DPI OFF OFF ONID5 Color 300DPI ON OFF ONID6 Color 400DPI OFF ON ONID7 Color 600DPI ON ON ON* The figures 1-3 above indicate the numbersof the DIP switch used to set the SCSI ID.Table 2-301
