4520-xxx Options Service Check Service Tip: When you have a problem with any of the options installed in the options slots on the interconnect board on a 212/414/ 616 (the 010 and 010 at service level B have only one slot), switch the non operating option to one of the other option slots to isolate the failure. Flash Memory Option(s) Run a copy of the test page and check to see if the option you are checking is listed. The printer does not recognize the option being installed if the option is not listed. Check to make sure that the Memory card is installed correctly and is not broken or damaged. If the Memory card is correctly installed not broken or damaged then run the "Flash Test" on page 3-4. If the test fails, replace the Flash card. If the problem continues, replace the controller board. DRAM Memory Option(s) This service check is the same as the flash memory option service check with the following exception: Run the "SDRAM Memory Test" on page 3-12 from the menu if the SDRAM Memory card is correctly installed and not broken or damaged. If the test fails, replace the SDRAM card. If the problem continues, replace the controller board. Hard Disk Option Service Tip: The Lexmark T printers support one hard disk option. Check to make sure only one hard disk option is installed. Check to make sure the fixed disk and the fixed disk board are correctly installed. Run the "Quick Disk Test" on page 3-2 from the Device Test on the Diagnostic Menu when a problem is suspected either with the hard disk system board or with the hard disk. Diagnostic Information 2-81
