EPL-7000 LASER PRINTER Memory Options The EPL-7000 comes with .5 MB of standard RAM. If you want to share the printer or if you regularly print complex pages using graphics and downloaded fonts, you may need to increase the RAM of your printer. You have three options for adding memory to your printer: l Increase the memory on the main controller board with memory chip sets. You can install up to three chip sets for a total of 2 MB of RAM. l Add one of two available memory expansion boards. The C822031 comes with .5 MB standard RAM, and the C822011 comes with 2 MB standard RAM. l Increase the memory on your memory expansion board with memory chip sets. Install up to four chip sets to the .5 MB board for a total of 2.5 MB additional RAM, or add up to four chip sets to the 2 MB board for a total of 4 MB additional RAM. Note: You must first expand the memory on your controller board to the maximum 2 MB capacity before you can add an optional memory board. The RAM chip sockets are located on the connector side of the controller board as shown below. As shown, there are three sectors, each with four chip sockets. The chip sockets are easily identified by the IC number. 26 27 26 The three sectors must be filled in the order given below: 1. Turn on the printer power and watch the display for the following: . All the indicator lights on the panel light briefly l The message ROM Check appears l The message RAM Check x.x MB appears. 2. Make sure that the amount of RAM displayed by the RAM check status message matches the new total RAM memory as shown below: Board with 2 chip sets (8 chips) Board with 3 chip sets (12 chips) If the correct amount of RAM does not appear, turn off the power and remove the board to check that the chip set is in the correct sector and that each chip is well-seated in its socket. If the RAM check message is still incorrect, contact your service representative for assistance. If insufficient memory is still a problem even after you increase the memory with memory chip sets, you can install a memory expansion board as described in the next section. 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. only after you have increased the printer's controller memory chip set. See Installing the memory chip set, 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. EPL-7000-6 1/7/91 Laser Printers
