Description/Action
900 RIP Software Unrecoverable RIP software error. May be the result of a code
malfunction, or failure of the RIP controller board.
901 Engine Flash An attempt was made to program the flash memory on the
engine board, and the programming failed. Replace the engine
board.
920 Fuser Error A problem with the fuser. Confirm that the fuser was installed
correctly and that all connections are made. If installation is
correct, replace the fuser.
927 Fan Stalled The cooling fan has stopped when it should be running. Check
the connection of the fan to the LVPS. If connections are correct,
check the LVPS for proper operating voltage of the fan as
described in the Wiring Diagram section of this manual. If voltage
check is incorrect, replace the LVPS. Otherwise, replace the fan.
930 Printhead Error The printer has detected a printhead motor abnormality. Check
the connection of the printhead cable to the printhead and
engine board. If connections are correct, check the engine board
for proper operating voltage of the printhead scanner motor as
described in the Wiring Diagram section of this manual. If voltage
is incorrect, replace the engine board. Otherwise, replace the
printhead.
939 RIP-Engine Comm. The engine board has not responded correctly to a command
from the RIP board after several tries. Check the connection
between the engine and RIP boards. If connection is good,
replace the engine board. If problem persists, replace the RIP
board.
952 Engine Error An engine board NVM abnormality. Replace the engine board.
953 NVRAM Failure A failure detected with the NVRAM chip on the RIP board.
Replace the RIP board.
954 NVRAM failure A failure detected with the NVRAM CRC on the RIP board.
Replace the RIP board.
955 Code CRC The code ROM or NAND failed the CRC check or the NAND
experienced an uncorrectable multi-bit failure. Replace the RIP
board.
956 System Board A processor failure on the RIP board. Replace the RIP board.
957 System Board A ASIC failure on the RIP board. Replace the RIP board.
958 NAND Failure The printer has performed more than 100 "shift and re-flash"
operations as a result of Error Correction Code bit corrections. It
is an indication that the NAND on the RIP board is failing.
Replace the RIP board.
959 NAND Failure A SRAM failure on the RIP board. Replace the RIP board.
960 Memory Error The RAM soldered on the RIP board is bad. Replace the RIP
board.
