This document provides part number and specification information for memory upgrades on various legacy HP LaserJet printers.

NOTE: The following part numbers may change or become discontinued without further notice.

HP LaserJet 5L / 6Lseries Printers

See Table 1 for memory SIMM part numbers or the HP LaserJet 5L or 6L series printers.

Table 1: Memory part numbers

1-MB SIMM	C3939A
2-MB SIMM	C3938A
4-MB SIMM	C3148A

The specifications for the above memory SIMMs are:

DRAM
5 Volt
70 nanoseconds (or slower, such as 70ns or 100ns)
Meets JEIDA Specifications

NOTE: An 8 MB SIMM from Kingston Technologies can be used in these printers.

HP LaserJet 4P, 4 Plus, 4V, 5P, 5, 5Si, and 6P series printers

See Table 2 for memory SIMM part numbers for the HP LaserJet 4P, 4 Plus, 4V, 5P, 5, 5SI and 6P series printers.

Table 2: Memory part numbers

1-MB SIMM*	C3130A (Discontinued)
2-MB SIMM	C3131A (Discontinued)
4-MB SIMM	C3132A (Discontinued)
8-MB SIMM	C3133A (Discontinued)
16-MB SIMM*	C3146A

The specifications for the above memory SIMMs are:

72 Pin
32 Bit (No Parity)
70 nanoseconds (or slower, such as 80 ns or 90 ns)
Presence Detect

NOTE: The 16-MB SIMM is not supported on the HP LaserJet 4P/4MP, and 4/4M printers. The 1-MB SIMM is not supported on the HP LaserJet 5Si/5Si MX and 5Si Mopier printers.

HP LaserJet IIISi, 4 and 4Si series printers

See Table 3 for memory SIMM part numbers for the HP LaserJet IIISi, 4 and 4Si series printers.

Table 3: Memory part numbers

8-MB SIMM	C2066A

The specifications for the above SIMM are as follows:

72 pin
36 bit (Parity)
80 nanoseconds
Presence Detect

NOTE: This memory is also compatible with the HP LaserJet 4P/4MP, 4 Plus/4M Plus and 4V/4MV printers. However, it is recommended to use the SIMM part numbers specific to those printers.

Presence detect must be present on all the above listed SIMMs.

HP LaserJet IIISi printers with serial numbers prior to 3200 cannot use the 8 MB SIMM (C2066A).

Presence detect requirements

Presence detect is the ability to report the size and speed of the SIMMs installed in an HP LaserJet printer to whomever is asking for the information. Without presence detect, the printer would be unable to recognize that additional memory had been installed.
