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.
