To confirm that the Hard Disk Drive is installed correctly, print a status sheet. If the drive is not listed on the status sheet, try reinstalling the drive. Make sure that the electronic connector on the Hard Disk Drive is securely connected to the socket on the circuit board. For instructions on how to print a status sheet, see “Printing a status sheet” on page 50.

Installing a Memory Module

Increasing the printer’s memory allows you to print complex or graphics-intensive documents. You can increase printer memory up to 768 MB by installing optional Dual In-line Memory Modules (DIMMs).

This printer has three DIMM slots, but one slot has a 64 MB DIMM already installed in it at the time of manufacture. To increase printer memory to its maximum of 768 MB, you have to purchase three 256 MB DIMMs and remove the original 64 MB DIMM.

You can purchase DIMMs from various vendors. Be sure they meet the following requirements:

DRAM type

Synchronous Dynamic RAM Dual In-line

 

Memory Module (SDRAM DIMM)

 

 

Memory size

32 MB, 64 MB, 128 MB, or 256 MB

 

 

Type

168-pin type, 64 bit, with SPD*

 

 

Access speed

66.66 MHz or higher (15 ns or less)

 

 

Height

Less than 40 mm

 

 

*SPD stands for Serial Presence Detect, a chip residing on the memory module that contains information about the size, speed, and other specifications of the memory as well as manufacturer information that can be retrieved by the motherboard through electronic signals.
