Remedy: Is the item that has reached the adjustment range (MIN or MAX), "Fast Scan Margin" or "Slow Scan Margin"? Y↓ N→Check the following: • Check that the value of dc131 NVM Read/Write [760-024] is "0". • The Imaging Unit (Y, M, C, K) for improper installation. If no problems are found, replace the following parts in sequence: • Imaging Unit (Y, M, C, K) • LPH Unit (Y, M, C, K) • Rear Holder Assembly Is the item that has reached the adjustment range (MIN or MAX) "Slow Scan Margin"? Y↓ N→Raise/lower the LPH (Y, M, C, K) 2 to 3 times to check the LPH lift up/down mechanism. If the problem persists, replace the LPH Unit (Y, M, C, K). Replace the MCU PWB.
