Service error codes (9xx) (continued)
Error Description
952 NV failure:n
954 NVRAM CRC failure
955 Code CRC <loc>
956 Controller card
957 ASIC failure
958 NAND failure
959 SRAM failure
960 RAM soldered on the
card is bad
961 RAM in slot 1 is bad
Action
Recoverable error. Reset (POR) the
printer. Where n=offset where error
occurred.
Indicates the NVRAM experienced a CRC
failure. Replace the controller card.
Replace the controller card. Where
<loc> = CRC Failure or ECC Failure on
the controller card.
Perform a power on reset (POR). If this
does not fix the problem, replace the
controller card.
Perform a power on reset (POR). If this
does not fix the problem, replace the
controller card.
Before proceeding, perform a power on
reset (POR) to see if the ECC (error
correction code) can reflash NAND.
If this does not fix the problem, replace
the controller card.
Perform a power on reset (POR). If this
does not fix the problem, replace the
controller card.
Indicates a DRAM Memory Error on the
controller card. Replace the controller
card.
If another SDRAM memory DIMM is
available, turn the power off, and switch
the DIMM. If the memory card now works
correctly, replace the failing DIMM. If this
does not fix the problem, replace the
controller card. If another DIMM is not
available, replace the memory option first
and then the controller card if necessary.
