The Memory Expansion Boards If you are having difficulty printing complex, graphics-intensive pages and you have already increased your printer's controller board memory to the maximum 2 MB with memory chip sets, you may need to install a memory expansion board. The .5 MB memory expansion board is an economical choice for adding memory to your printer. This board adds .5 MB of additional RAM to the printer. You can increase the base memory on this board to a total of 2.5 by adding up to four memory chip sets. Combined with the 2 MB on your controller board, the .5 MB board can increase total available RAM to 4.5 MB. The 2 MB memory expansion board adds an extra 2 MB of RAM to your printer. In addition, you can increase the base memory on the expansion board to a maximum of 4 MB by installing up to four optional memory chip sets. Thus, you can increase printer memory to a maximum of 6 MB with the 2 MB board. CAUTION: A memory expansion board can be installed only after you have increased the printer's controller board memory to the maximum 2 MB with the optional memory chip set. See Installing the memory chip set, earlier in this appendix for more information. The procedure for adding additional memory to the memory expansion board is the same for either board. You can use the same type of memory chip sets that you used to increase the memory on your controller board. A-42 Appendix A
