EPL-8000 Installing chip sets on the controller board The RAM chip sockets are located on the upper right side of the controller board. 3. Gently press the chip halfway into the socket. If it goes in at an angle, remove it with a chip puller or a small flat-head screwdriver; then reinsert the chip. CAUTION: Be careful not to scratch the chip or the board when removing the chip. 4. Once the chip is properly inserted, push down firmly on both ends to make sure it is fully seated. There are two sectors on the board, each containing four chip sockets (identified by their IC numbers), as shown below. 17 IO 16 I I I5 12 14 13 If both two sectors are empty, install the fist chip set in sector 1. If sector 1 is already filled, install the second chip set in sector 2. sector IC number Total RAM when hllea I IO. 11. 12. 13 1 SMB 2 14. 15. 16. 17 2M0 Q1 ! CAVIION: You cannot install a zMB chip set on the controller board: you can only use the SMB chio sets. Follow these steps to install a memory chip set: Make sure all the pins on the chip are aligned. They should point inward at slightly less than a 90' angle, as shown below. 0 - K ---====a If any of the pins are bent incorrectly, gentiy push them back into alignment. Line up the pins on the RAM chip with the holes in the socket. Be sure that the small notch on the end of the chip is toward your right. 5. Repeat steps 1 through 4 for each of the remaining chips. 6. Reinstall the interface card, if necessary. Installing chip sets on the memory expansion board There are four sectors on the memory exp,ansion board, each containing four chip sockets (identified by their IC numbers). The four sectors must be filled in alphabetical order. For example, if you are installing your first chip set, install it in sector A. Then install your next chip set in sector B and so on. See the table under "Selecting a memory option," earlier in this section. for a list of the RAM configurations possible the memory expansion board. Before you install the chips, check their pin alignment as described in step 1 of the previous seclion. Then follow these steps: 1. Place the expansion board on your work surface with the components facing up. 2. Align the chip's pins with the holes in the socket. Be sure the small notch on the end of the chip is facing in the direction shown below. Laser Printers
