Description
The NVRAM chip failure with controller part.
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 Pn 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 Bn
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.
Controller board failure. Processor failure.
Check on .02 for fan error.
Controller board failure. ASIC failure.
Printer has performed more than 100 "shift and
reflash" operations as a result of ECC bit
corrections.
Controller verification failure of system boot
code.
System hardware failure.
RAM memory error: RAM soldered on the
board is bad.
RAM memory error: slot 1 RAM is bad.
RAM memory error: slot 2 RAM is bad.
