• Code: E011
• Description: Transfer belt paper-clinging jam: The paper after the 2nd transfer is clinging to the transfer belt, or a paper jam occurred between the registration roller and the paper clinging detection sensor.
• Causes: Process unit Registration motor LGC board Paper clinging detection sensor Registration roller
• Remedy: roller Drawer Check if paper is folded at the leading edge. Registration guide Replace the registration guide. No scratches on the paper leading edge Drawer Check if paper is folded at the leading edge. Check that paper is not skewed in the side guides of the drawer. Process unit Clean the process unit or replace it. Paper clinging detection sensor Clean the sensor Clean the facing section of the sensor. All Registration motor • Motor check (Perform the input check: 03-108/ 158) • Connector check (CN332) • Harness check LGC board • Board check • Connector check (CN332, CN337) • Harness check Paper clinging detection sensor • Sensor check (Perform the input check: 03- [ALL]OFF/[7]/[E] ) • Connector check (CN337) • Harness check Check of the 2nd transfer roller connection Check that the 2nd transfer roller shaft is securely grounded via the frame. • Check if the bearing and the leaf spring contact properly. • Check if the shaft tip and the leaf spring contact properly, and that conductive grease is applied. Change of the 2nd transfer bias If the leading edge of paper clings to the 2nd transfer roller and causes paper jamming, change the 2nd transfer roller bias correction factor of the leading/trailing edge of the paper. (The larger the value, the smaller the transfer voltage of the leading/trailing edge of the paper.) Codes to be changed (Initial value of the transfer bias of the leading/trailing edge of the paper: 0) • Color mode print (top side): 05-2938-* • Color mode print (back side): 05-2939-* • Black mode print (top side): 05-2940-* • Black mode print (back side): 05-2941-* Sub codes:* -> Plain paper: 0, Recycled paper: 7 Notes: After these codes are changed, perform solid duplex-printing and check that there is no faint or void image on the leading/trailing edge of the paper.

• Code: E020
• Description: Stop jam at the exit sensor: The trailing edge of the paper does not pass the exit sensor after its leading edge has reached this sensor.
• Causes: Separation plate of the fuser unit Separation finger of the fuser unit Exit sensor LGC board
• Remedy: Paper jamming at separation finger in the Fuser Unit. Fuser unit Clean the separation finger. Check if the fingers or springs of the separation finger are securely attached.
