Options Service Check
Service Tip: When you have a problem with any of the options
installed in the options slots on the interconnect board, switch the
non operating option to one of the other option slots to isolate the
failure.
Serial Port Service Check
Run the “Serial Wrap Tests” on page 3-17.
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
RIP board.
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. 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 3-22. If the test fails,
replace the Flash card assembly. If the problem continues, replace
the
RIP 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 3-13 from the menu if the
DRAM Memory card assembly is correctly installed and not broken
Belt Unit Check the transfer belt unit for
scratches or nicks. Be sure there is
no toner buildup on the belt. Replace
the belt unit if it is damaged.
