4045-XXX Options Service Check 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 DIMM is installed correctly and is not broken or damaged. If the Memory DIMM is correctly installed not broken or damaged then run the "Flash Test" on page 3-19. If the test fails, replace the FLASH DIMM. 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 "DRAM Memory Test" on page 3-9 from the menu if the DRAM Memory DIMM is correctly installed and not broken or damaged. If the test fails, replace the DRAM DIMM. If the problem continues, replace the controller board. Hard Disk Option Check to make sure the fixed disk and the fixed disk board are correctly installed. Run the "Quick Disk Test" on page 3-17 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. Note: The Quick Disk Test is a non-destructive test and indicates Pass or Fail. If the test fails, replace the hard disk. If a problem still exists, replace the hard disk board. The "Disk Test/Clean" on page 3-18 is used to help restore the disk if the disk contains bad data and is unusable. This test is divided into a cleaning and a verifying or testing section. WARNING: This can be a very lengthy test depending on the disk size. This test leaves the hard disk unformatted. The servicer or user must reformat the disk using the Format Disk Menu operation. This is a destructive type of test. All the data on the disk is destroyed and should not be performed on a known good disk. 2-32 Service Manual
