The BCU has three CPUs (Main, MUSIC, and DSP). The CPUs control the 
following functions: 

Main CPU 

• 

Engine sequence 

• 

Machine and printer engine operation 

• 

Timing for peripherals 

• 

High voltage supply, laser, and fusing 

• 

Sensors, drive board, and solenoids 

• 

Motors 

MUSIC (Mirror Unit for Skew and Interval Correction) CPU 

• 

TD sensor 

• 

Line position adjustment 

• 

Memory chip on the toner cartridge 

DSP (Digital Signal Processor) 

• 

Line position adjustment 

 

Controller: 

The controller handles the following functions: 

• 

Printer-to-host interface 

• 

Operation panel interface 

• 

Network interface 

• 

Interfacing and control of the optional USB, Bluetooth, IEEE1394, 
IEEE802.11b (wireless LAN), HDD, and DRAM DIMM 

 

LD Drive Board: 

This is the laser diode drive circuit board. 
 

DRB: 

The DRB (driver board) controls the paper feed motor, development motors 
(color/black), drum drive motors (color/black), transfer unit drive motor, and transfer 
voltage. 
 

IEEE1394 Interface (Option): 

This allows computers to connect to this printer using an IEEE1394 interface.
