• Code: 3-1 ... 3-5
• Description: 3-1 JS0 3-2 JS1 3-3 JS2 3-4 JS3 3-5 JS4 indicates JAM
• Remedy: Paper Jam/Exit - When the paper was not fed to Exit Sensor within the specified time. - When Exit Sensor turned ON in warming up. Paper Jam/Exit - When paper was not fed to Exit Sensor within the specified time after SENSOR REGI OFF. Paper Jam/Exit - When the paper was fed out from Exit Sensor earlier than the specified time. Paper Jam/Tray to Regi - When the paper was fed to Regi Sensor earlier than the specified time. - Paper interval became narrow than the specified time because of the two or more papers are fed at a time. - Paper size error. The paper longer than Legal 14” is used. Paper Jam/Misfeed - When the paper did not reach Regi position within the specified time. Paper Jam/Regi to Fuser - When the paper did not reach Fuser from Regi position within the specified time.

• Code: 3-6
• Description: Paper Size Mismatch - Paper size detected by the Paper Size Switch or set in the NVRAM does not match the paper length obtained from ON time of Regi Sensor at feeding.
• Remedy: FIP1.12 Possible causative parts: 150 FEEDER ASSY 150 PAPER CASSETTE SENSOR REGI ACTUATOR B HVPS/MCU GUIDE TRAY LEFT 550 FEEDER ASSY 550 PAPER CASSETTE 1 Checking the paper size setup Does the paper size in use match the size setup by GUIDE ASSY END or by the driver on the PC? Go to step 2. Replace the paper, or change the paper size setting. 2 Checking NVRAM data Does NV01 Configuration 2 meet the specifications? Go to step 3. Modify the memory data. 3 Checking Regi Sensor Remove EP CARTRIDGE. Keep the lever of INTERLOCK S/W pushed as opening COVER OPEN . Does the number of Sensor/Switch Check increase one by one, when ACTUATOR B of SENSOR REGI is pushed and released? Checks by Chapter 2 Diagnostic [Sensor/Switch Check]. Go to step 4. Go to FIP2.5 SENSOR REGI. 4 Checking the paper feeding tray Is the paper supplied from Tray 1 or Tray 2, when Error is occurred? Go to step 5. Go to step 6. 5 Checking Paper Cassette (1) Are GUIDE ASSY END, GEAR SECTOR, RACK SIZE, LINK SW SIZE1/2/3 of Paper Cassette of Tray 1 or Tray 2 installed correctly? Go to FIP2.17 GUIDE TRAY LEFT. Reinstall the parts causing Error. 6 Checking the paper tray Is the paper supplied from Tray 3 or Tray 4 when Error is occurred? Go to step 7. Replace HVPS/MCU. 7 Checking Paper Cassette (2) Are GUIDE ASSY END, GEAR SECTOR, RACK SIZE, LINK SW SIZE1/2/3 of Paper Cassette of Tray 3 or Tray 4 installed correctly? Go to FIP2.24 OPT ASSY SIZE.
