• Code: E722
• Description: ADF document jam
• Causes: Regist paper sensor stuck jam/detection of out-of-spec oversized documents – Once the regist paper sensor becomes active, it does not become inactive when the fed document is transferred to the distance exceeding the maximum page size. (Simplex and Duplex)
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.

• Code: E723
• Description: ADF document jam
• Causes: Detection of out-of-spec undersized documents – Once the regist paper sensor becomes active, it becomes inactive before the fed document is transferred by the distance equal to the minimum page size. (Simplex and Duplex)
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.

• Code: E724
• Description: ADF document jam
• Causes: Scan sensor stuck jam – The scan sensor does not become inactive even when the fed document is transferred by 60mm after the regist paper sensor becomes inactive. (Simplex and Duplex)
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.

• Code: E725
• Description: ADF document jam
• Causes: Detection of a too little space between documents – Before the document is transferred by 31mm after the regist paper sensor becomes inactive, the sensor becomes active. Detection of a too little space between the documents. (Simplex)
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.

• Code: E726
• Description: ADF document jam
• Causes: Activation of the reverse paper sensor for the documents not to be reversed – Switching to the first separator is not carried out normally causing activation of the reverse paper sensor. (Simplex and Duplex) • The reverse paper sensor becomes active in feeding of a simplex document. • The reverse paper sensor becomes active between reversal to the back and activation of the regist paper sensor.
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.

• Code: E727
• Description: ADF document jam
• Causes: Activation of a sensor at an unintended timing – The scan sensor, regist paper sensor, hopping sensor or reverse paper sensor becomes active at an unintended timing. (Simplex and Duplex)
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.

• Code: E728
• Description: ADF document jam
• Causes: Detection of chattering of a sensor – Chattering of a sensor is detected. Once a sensor becomes active, the sensor becomes inactive in 5mm feeding of the document. Then the inactive sensor becomes active in the next 5mm feeding. (Simplex and Duplex)
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.

• Code: E741
• Description: ADF document jam
• Causes: Reverse paper sensor stuck jam/ detection of out-of-spec oversized documents – The reverse paper sensor does not become inactive when the document is transferred to the distance exceeding the maximum page size. (Duplex)
• Remedy: Open the ADF cover, remove every jammed document from the paper feed path, and close the ADF cover.
