6.1.1 Copy & Scan Document Path
6.1.2 Printer Paper Path
1) After receiving print job, the printer feeds the printing paper from the cassette or manual feeder.
2) The fed paper passes the paper feeding sensor. (Jam 0 occurs if the sensor is not operated after certain time passes)
3) The paper passes the paper feeding sensor moving to the paper exit sensor via printing process. (Jam 1 occurs if the sensor is not operated after a certain time passes)
4) The paper passed the paper exit sensor moving out from the set. (Jam 2 occurs if the sensor is still operated after a certain time passes.)

6.2 Clearing Paper Jams
Occasionally, paper can be jammed during a print job. Some of the causes include:
• The tray is loaded improperly or overfilled.
• The tray has been pulled out during a print job.
• The front cover has been opened during a print job.
• Paper was used that does not meet paper specifications.
• Paper that is outside of the supported size range was used.
If a paper jam occurs, the On Line/Error LED on the control panel lights red. Find and remove the jammed paper. If you don’t see the paper, open the covers. Do not use a tweezers or a sharp metal tool when removing a jam. The covering of a metal part can be removed which can cause an electric leakage.

By selecting the correct paper types,most paper jams can be avoided. If a paper jam occurs, follow the steps outlined in “Clearing Paper Jams ”
• Follow the procedures in “Loading Paper ” .Ensure that the adjustable guides are positioned correctly.
• Do not overload the paper tray.Ensure that the paper is below the paper capacity mark on the inside wall of the paper tray.
• Do not remove the paper from the tray while printing.
• Flex, fan and straighten the paper before loading.
• Do not use creased, damp or highly curled paper.
• Do not mix paper types in the paper tray.
• Use only recommended print materials. See “Paper Specifications ”
• Ensure that the recommended print side is facing down when loading paper in the paper tray and facing up in the Bypass tray.
