In order to use the product with safety
In order to use the product with safety, make sure to read the user's manual (this manual) before using
the product.
General Caution
Do not touch the safety switch of the internal parts of the printer. Electric shock may
occur due to the occurrence of high pressure. The rotation of the gear may also cause
injury.
Do not use an extremely flammable spray around the printer. Fire may occur because of
parts with high temperature.
Please let our staff in Customer Center know after unplugging mains connector when
the cover gets extremely hot, is smoking, emits questionable odor, or is making strange
noise. Fire may occur.
Please let our staffs in Customer Center know after unplugging mains connector when
liquid such as water goes into the printer. Fire may occur.
Please take a foreign object away after unplugging when you drop foreign objects such
as clips into the printer. That situation may case electric shock, fire, and/or injury.
Do not conduct an operation or an analysis other than specified in user's manual. That
situation may case electric shock, fire, and/or injury.
Please let our staffs in Customer Center know after unplugging mains connector when
the printer has fallen down or damaged. That situation may case electric shock, fire, and
injury.
Do not connect the power cord, the printer cable, or the ground wire other than in-
structed in user's manual. Fire can be induced if misused.
Do not insert objects at the vent hole. Do not operate the printer with the rear cover
opened. Electric shock, fire, and/or injuries may occur.
Do not place a cup with liquid on the printer. Electric shock, fire, and/or injuries may
occur.
Risk of explosion if battery is replaced by an incorrect type.
Battery of the printer need not to be replaced. Do not touch the battery.
Replace the whole board to replace the CU main board.
In the case of replacing batteries at board repairs, replace with the specified type ones. In-
stallation of another type batteries may result in explosion.
Caution for used batteries are as follows; do not recharge, force open, heat or dispose
of in fire.
When open the printer cover, do not touch the fuser unit. You may get burned.
Do not throw toner cartridges, or image drum cartridges into fire. You may get burned by
dust explosion.

Rev. 1 5 /
Do not go near an ejection area while the power is on and in printing. You may get
injured.

2.1 Main Control PCB
Main Control PCB (ASP-PWB) (1200dpi)
Figure 2-2-1 illustrates the block diagram of the Main Control PCB (ASP PWB).
Figure 2-2-1

Rev. 1 18 /
The Main Control PCB of the 1200dpi printer consists of a CPU, RAM, HDD, CompactFlash, SouthBridge
LSI, EEPROM, KeyChip, PCI Bus Option and Advanced Interface.
(1) CPU
1GHz Transmeta TM5800 CPU.
(2) RAM
There are 3 types of RAMs. SDRAM DIMM is the only user option RAM. The DDR and
video RAM configuration is fixed and cannot be modified. Only the total memory of the
DDR and SDRAM DIMM is recognized as a usable RAM within the system configuration.
DDR : This is 256MB and 266MHz in speed, and directly soldered on the ASP PCB.
SDRAM DIMM: 128, 256, and 512MB; 133MHz speed, 144p DIMM mounted in DIMM slot.
Video RAM : RAM that is directly soldered on ASP PCB for the video LSI.
(3) HDD/CompactFlash
The 1200-dpi program is stored in a storage medium. Depending on the model, the system
is equipped with HDD or CompactFlash. However, HDD may be added as an option to
a model with CompactFlash. HDD is a mold assembly similar to the one for the 600-dpi
system.
(4) SouthBridge LSI
This is a ALI-make BGA package LSI. It mainly controls the USB I/F, Centro I/F, image
processing LSI, Ethernet board, and MFP extension board via the PCI bus.
(5) Image Processing LSI
This is an EFI-make BGA package LSI. It is mainly for image processing.
(6) EEPROM
This is a 3.3V/256kbit EEPROM with an 8-pin DIP package mounted on the IC socket.
It stores various settings that the control unit manages.
(7) KeyChip
The KeyChip is an 8-pin DIP package mounted on the IC socket. It is purchased from
EFI and stores EFI management information.
(8) PCI Bus
100-pin: An MFP extension board is available as optional equipment.
68-pin: A LAN card is provided as standard equipment.
(9) Advanced Interface
Standard : Centronic Parallel I/F (IEEE-1284)
USB (USB2.0) I/F
Ethernet Board
Additional PCB : MFP Extension Board (PCI BUS Connection)
