Installing Flash SIMMs in the Hewlett Packard 4V
Your HP LaserJet printer has four SIMM (Single In-line Memory Module) slots. Use them to install additional printer memory and printer personalities (such as the Flash SIMM).
The HP LaserJet 4V printer comes with 4 MBytes of volatile RAM memory and can be expanded to 68 MBytes.
The HP LaserJet 4MV printer contains 12 MBytes of volatile RAM memory. By adding optional 1, 2, 4, 8, or 16 MByte SIMMs you can increase memory to a total of 44 MBytes.
Note: RAM Memory SIMMs for the HP LaserJet 4 Plus and 4M Plus printers can be used in the HP LaserJet 4V and 4MV printers. PostScript language SIMMs for the HP LaserJet 4 Plus and 4M Plus printers cannot be used in the HP LaserJet 4V and 4MV printers. Flash SIMMs for the HP LaserJet 4P and 4MP printer can be used in the HP LaserJet 4V and 4MV printers if the blue jumper on the Flash SIMM is replaced before the SIMM is installed in the HP LaserJet 4V or 4MV.
SIMM boards and your printer controller board can be damaged by small amounts of static electricity. Wear an antistatic wrist strap or touch the surface of the antistatic package before touching a board. When handling a board, wear an antistatic wrist strap or frequently touch the antistatic bag or bare metal on the printer.
Test the SIMM by sending the PCL codes to call the images on the SIMM if it has previously been programmed.
