5016-001 Options Service Checks When you have a problem with any of the options installed in the options slots on the interconnect board, switch the non-operating option to one of the other option slots, to isolate the failure. Flash Memory Option(s) Service Check Run a copy of the test page and verify the option you are checking is listed. The printer does not recognize options installed, if those options are not listed. Be sure the Memory SIMM is installed correctly and not broken or damaged. If the Memory SIMM is correctly installed, not broken or damaged, run the "Flash Test" on page 3-17. If the test fails, replace the Flash SIMM. If the problem continues, replace the controller board. DRAM Memory Option(s) Service Check This service check is the same as the flash memory option service check with the following exception: If the DRAM Memory SIMM is correctly installed and not broken or damaged, run the "SDRAM Memory Test" on page 3-10 from the menu. If the test fails, replace the DRAM SIMM. If the problem continues, replace the controller board. 2-106 Service Manual
