C Memory and Personality SIMM Installation Note Table C-1 Your HP LaserJet 5Si/5Si MX/5Si NX has four single inline memory module (SIMM) slots for memory expansion. For the 5Si/5Si NX, all four are available for expansion. For the 5Si MX, one slot is occupied by a 8 MByte memory SIMM and another slot is occupied by a SIMM holding Adobe's PostScript Level 2 language. Therefore, there are two available slots that you can use to install additional printer memory and printer personalities. The printer contains 4 MBytes of on board memory. By adding optional SIMMs with 2, 4, 8, 16, or 32 MBytes, you can increase memory to a total of 76 MBytes (for the 5Si MX). Memory SIMMs for the HP LaserJet 4 Plus and 4M Plus printers can be used in the HP LaserJet 5Si series. PostScript language SIMMs for any other printer cannot be used in the HP LaserJet 5Si series. When you get a new memory board, compare the part number on the outside of the package to the part number in Table C-1 below. If you have not received the correct SIMM, notify your authorized Hewlett-Packard dealer.
