Please follow the procedure below after you replaced the SBU assy.

Adjust the following SP modes after you replace the sensor board unit:
• SP4–008 (Sub Scan Mag)
• SP4–010 (Sub Mag Reg.)
• SP4–011 (Main Scan Reg)
• SP4–688 (DF: Density Adjustment). This SP code adjusts the density level if the ID of outputs made in
the DF and Platen mode is different.

gudluck.......!!!!!
