Error code
Description
Action
954.xx
Service NVRAM Failure
The NVRAM chip failure with controller part.
•
POR the printer.
•
If the problem persists, then replace the
controller board. See
“Controller board
removal” on page 239
.
955.xx
Service Code CRC <loc>
The Code ROM or NAND flash failed the Cyclic
Redundancy Check (CRC) check or the NAND
experienced an uncorrectable multi-bit failure.
<
loc
> indicates the source of the failure and has
one of the following values:
•
CRC Failure: The source is a failing package
indicated by P
n
where
n
is the package
number. This error could occur on a
controller with ROM or NAND flash and
could occur as a result of the CRC check
done when the machine is powered on. The
range of package numbers is from 0 to 15.
•
Error Correction Code (ECC) Failure: The
source is a failing page indicated by B
n
where “
n
” is the page number. This error
occurs only if a multi-bit failure is detected
during the ECC execution. Single bit failures
will be corrected automatically and will not
result in a service error. The range of page
numbers is from 0 to 1023.
956.xx
Service Controller Board
Controller board failure. Processor failure.
Check on .02 for fan error.
957.xx
Service Controller Board
Controller board failure. ASIC failure.
958.xx
Service NAND Failure
Printer has performed more than 100 “shift and
reflash” operations as a result of ECC bit
corrections.
959.xx
Service Invalid Firmware
Controller verification failure of system boot
code.
•
Update the firmware.
•
POR the printer.
•
If the problem persists, then replace the
controller board. See
“Controller board
removal” on page 239
.
959.0x
Service System Board
System hardware failure.
•
POR the printer.
•
If the problem persists, then replace the
controller board. See
“Controller board
removal” on page 239
.
960.xx
Service Memory Error
RAM memory error: RAM soldered on the
board is bad.
961.xx
Service Memory Failure
RAM memory error: slot 1 RAM is bad.
•
Check RAM in slot 2.
•
If RAM is ok, then POR the printer.
•
If the problem persists, then replace the
controller board. See
“Controller board
removal” on page 239
.
962.xx
Service Memory Failure
RAM memory error: slot 2 RAM is bad.
