Option card service check
Serial port
Run the “Serial Wrap Test” on page 3-22.
Note: The Serial Wrap Test is designed to check the serial port hardware by using a wrap plug, P/N
1329048, and invoking the Serial Post Diagnostic Test. The test helps isolate the printer from the serial
cable and host computer. The test provides failure information on the display for approximately three
seconds. If the test indicates a problem, replace the option card. If the problem continues, replace the RIP
board.
Flash options
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. Be sure the memory card assembly is installed
correctly and is not broken or damaged. If the Memory card assembly is correctly installed, not broken or
damaged, then run the “Flash Test” on page 3-24. If the test fails, replace the Flash card assembly. If the
problem continues, replace the RIP board.
DRAM options
This service check is the same as the flash memory option service check with the following exception: Run the
“DRAM Test” on page 3-21 from the menu if the DRAM Memory card assembly is correctly installed and not
broken or damaged. If the test fails, replace the DRAM card assembly. If the problem continues, replace the RIP
board.
