Adjustment after LD unit replacement
Do the following settings after replacing the laser unit.
These operations are for initializing the D-Phase data and shading data after LD unit
replacement.
1. Plug in and turn on the main power switch of the machine.
2. Enter the SP mode.
3. Select the SPs of the replaced LD unit, and set them to “1”.
SP2-180-004 (Black/cyan)
SP2-180-006 (Black/cyan)
SP2-180-005 (Magenta/yellow)
SP2-180-007 (Magenta/yellow)
4. Exit from SP mode.
5. Turn the main power switch off and on.
These are adjustments for skew adjustment.
1. Unplug and turn off the main power switch of the machine.
2. Execute ‘MUSIC’ (SP2-111-002) and check the result for each color with the following SPs.
SP2-117-004 (Black)
SP2-117-002 (Cyan)
SP2-117-001 (Magenta)
SP2-117-003 (Yellow)
3. The color skew adjustment should only be executed if one or more of the above SP values is
not within ±5. No skew adjustment is required when all SP values are within ±5. However, if
one or more of the SP values is not within ±5, then you must adjust color skew for any color
that has an SP value that is not 0.
4. Open the front door and then remove the paper exit tray (
p.4-41).
5. Close the front door and execute “MUSIC” (SP2-111-002).
