Options Problem After installing additional memory (memory chip set or a memory expansion board), the printer does not function as expected. Solution After you turn on the power, the RAM Check message does not display the expected amount of memory. The RAM chips or the optional memory board may not be installed correctly. Turn off the printer and check the installation. Make sure that the chips are installed in the correct sector of the main board and that each chip is firmly seated in its socket. Also make sure that the notches on the chips are all pointing in the correct direction. See Appendix A for more information. You may not have increased memory on the printer's controller board before you installed the memory expansion board. A memory expansion board can be installed only after you have increased the controller board memory to the maximum 2 MB with the optional memory chip set. See Appendix A for more information. 7-46 Troubleshooting
