Description: RC Sample Lateral Fail-A1. There is an error with the Cyan fast scan position that is used as a reference during A1 (fine adjustment pattern) and C patch detection. (This is a hidden failure. The Color Regi Spec cannot be guaranteed and Data is only recorded in history.)
Remedy: Check the installation status of the IBT Assembly. Is the IBT Assembly installed properly? Y↓ N→Install the IBT Assembly properly. Replace the IBT Assembly
Code: 389.601
Description: RC Sample Block Fail-A1-In. During the A1 (fine adjustment pattern) and C patch detection, the patch at the MOB Sensor In side did not satisfy the defined number of valid sample blocks. (This is a hidden failure. The Color Regi Spec cannot be guaranteed and Data is only recorded in history.)
Remedy: 1. Check the detection section of the MOB Sensor for contamination, the connectors for disconnection, and the connections for open circuit, short circuit, and poor contact. If no problems are found, replace the MOB ADC Assembly.
Code: 389.603
Description: RC Sample Block Fail-A1-Out. During the A1 (fine adjustment pattern) and C patch detection, the patch at the MOB Sensor Out side did not satisfy the defined number of valid sample blocks. (This is a hidden failure. The Color Regi Spec cannot be guaranteed and Data is only recorded in history.)
Remedy: 1. Check the detection section of the MOB Sensor for contamination, the connectors for disconnection, and the connections for open circuit, short circuit, and poor contact. If no problems are found, replace the MOB ADC Assembly.
Code: 389.604
Description: RC Sample Block Fail-B-#1-In. During the B (rough adjustment pattern) patch detection, the #1 (Yellow) patch at the MOB Sensor In side did not satisfy the defined number of valid sample blocks. (This is a hidden failure. The Color Regi Spec cannot be guaranteed and Data is only recorded in history.)
Remedy: Check the density of Y color. Is the density of Y color normal? Y↓ N→Adjust to correct the density of Y color. Check the connection between the MOB Sensor In P/J150 and the MCU PWB P/J415 for connector disconnection, open circuit, short circuit, and poor contact. Is the connection normal? Y↓ N→Connect the MOB Sensor In P/J150 to the MCU PWB P/J415 properly. Check the Y Magnet Roll for contamination, scratches, and distortion. Is the Magnet Roll normal? Y↓ N→Replace the Developer (Y) (PL 5.2 Item 9). Check the Transfer Belt for contamination, scratches, and distortion. Is the Transfer Belt normal? Y↓ N→Replace the IBT Assembly. Check the Y Imaging Unit for contamination, scratches, and distortion. Is the Imaging Unit normal? Y↓ N→Replace the Imaging Unit (Y) Replace the MOB ADC Assembly. If the problem persists, replace the MCU PWB.
Code: 389.606
Description: RC Sample Block Fail-B-#1-Out. During the B (rough adjustment pattern) patch detection, the #1 (Yellow) patch at the MOB Sensor Out side did not satisfy the defined number of valid sample blocks. (This is a hidden failure. The Color Regi Spec cannot be guaranteed and Data is only recorded in history.)
Remedy: Check the density of Y color. Is the density of Y color normal? Y↓ N→Adjust to correct the density of Y color. Check the connection between the MOB Sensor Out P/J151 and the MCU PWB P/J415 for connector disconnection, open circuit, short circuit, and poor contact. Is the connection normal? Y↓ N→Connect the MOB Sensor Out P/J151 to the MCU PWB P/J415 properly. Check the Y Magnet Roll for contamination, scratches, and distortion. Is the Magnet Roll normal? Y↓ N→Replace the Developer (Y) (PL 5.2 Item 9). Check the Transfer Belt for contamination, scratches, and distortion. Is the Transfer Belt normal? Y↓ N→Replace the IBT Assembly. Check the Y Imaging Unit for contamination, scratches, and distortion. Is the Imaging Unit normal? Y↓ N→Replace the Imaging Unit (Y). Replace the MOB ADC Assembly. If the problem persists, replace the MCU PWB.
Code: 389.607
Description: RC Sample Block Fail-B-#2-In. During the B (rough adjustment pattern) patch detection, the #2 (Magenta) patch at the MOB Sensor In side did not satisfy the defined number of valid sample blocks. (This is a hidden failure. The Color Regi Spec cannot be guaranteed and Data is only recorded in history.)
Remedy: Check the density of M color. Is the density of M color normal? Y↓ N→Adjust to correct the density of M color. Check the connection between the MOB Sensor In P/J150 and the MCU PWB P/J415 for connector disconnection, open circuit, short circuit, and poor contact. Is the connection normal? Y↓ N→Connect the MOB Sensor In P/J150 to the MCU PWB P/J415 properly. Check the M Magnet Roll for contamination, scratches, and distortion. Is the Magnet Roll normal? Y↓ N→Replace the Developer (M) (PL 5.2 Item 8). Check the Transfer Belt for contamination, scratches, and distortion. Is the Transfer Belt normal? Y↓ N→Replace the IBT Assembly Check the M Imaging Unit for contamination, scratches, and distortion. Is the Imaging Unit normal? Y↓ N→Replace the Imaging Unit (M) Replace the MOB ADC Assembly. If the problem persists, replace the MCU PWB.
