This section explains names and functions of the parts on the rear side of the printer.
1. Optional Interface Board Slots
Optional interface boards can be inserted.
Insert an optional Gigabit Ethernet board, IEEE 802.11b interface unit, Bluetooth interface unit or IEEE1284
interface board in the left slot.
Insert a USB host board in the right slot.
2. Expansion Card Slots
Insert a security, digital camera or encryption card.
3. Controller Board
Slide this out to install options such as the SDRAM module or User Account Enhance Unit.
4. Ventilator
Releases heat from internal components to prevent overheating. Do not place objects against or near these holes.
Doing so results in printer malfunction.
Replace the dustproof filter when the "Replacement Alert/Replace IntTrans Unit soon." message appears on the
display. Replace it with the intermediate transfer unit together.
5. Power Connector
Connect the power cable to the printer. Insert the other end into an electrical outlet.
6. Drying Heater Switch
If the paper in the paper tray is moist due to high humidity, the print quality may decrease. The drying heater
prevents moisture. If humidity is high, turn the switch on.
7. Ethernet Port
Use a network interface cable to connect the printer to the network.
