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 2450 or 1650 (the 1250 has 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 SIMM is installed correctly and is not broken or damaged. If the Memory SIMM is correctly installed not broken or damaged then run the “Flash Test” on page 3-3 . If the test fails, replace the FLASH SIMM. 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 3-10 from the menu if the DRAM Memory SIMM is correctly installed and not broken or damaged. If the test fails, replace the DRAM SIMM. If the problem continues, replace the controller board.
