• Description: Paper Jam
• Remedy: Carefully pull the paper out, and perform a POR. If the problem remains, then replace the All-In-One.
  Paper jam appears on the LCD display after the POST. Pressing will clear the paper jam. When printing jam occurs at: – leading edge: feed roll – trailing edge : input tray Lift the scanner assembly. Turn on the All-in-One, and check the feed roll for rotation. If it does not rotate, then replace the carrier frame assembly. Go to “Carrier frame assembly removal”. Paper jam appears on the LCD display after the POST. Pressing will clear the paper jam. When printing jam occurs at: – leading edge: feed roll – trailing edge: input tray Lift the scanner assembly. Turn on the All-in-One, and check the feed roll for rotation. If the rotation takes less than 1 second, then check the following: • Wheel encoder for ink contamination. If contaminated with ink, then replace the carrier frame assembly. Go to “Carrier frame assembly removal”. • Paper feed encoder dial sensor for proper connection. If properly connected, then replace the paper feed encoder dial sensor. Go to “Paper feed encoder dial sensor removal”. • NS wiper for wear, damage, or looseness. If damaged, then replace the carrier frame assembly. Go to “Carrier frame assembly removal”. Paper jam appears on the LCD display after the POST. Pressing will clear the paper jam. When printing paper pick does not pick paper and Paper jam appears on the LCD display. • Check the paper pick motor connector J1 for proper connection. • Check the paper pick encoder dial sensor connector J28 for proper connection. • Check the pick motor belt for wear or damage. If any of these is not working, then replace the paper pick assembly. Go to “Paper pick assembly removal”. Otherwise, replace the paper pick encoder dial sensor. Go to “Paper pick encoder dial sensor removal”. Paper jam appears on the LCD display after the POST. Pressing will NOT clear the paper jam, cannot proceed printing. Check the End-Of-Form (EOF) flag sensor for mechanical damage. If damaged, then replace the carrier frame assembly. Go to “Carrier frame assembly removal” on
