Lexmark E120 - LVPS;HVPS Failure; NVRAM Failure

Diagnostic information 2-21
4506-1xx
LVPS/HVPS failure
NVRAM failure
Error codes 950–954 indicate a problem in the NVRAM (nonvolatile random access memory). Replace the
operator panel assembly. Codes 955–959 indicate a failed controller card. Replace the controller card. See
“Controller card removal” on page 4-17.
Note: NVRAM is on the operator panel printed circuit board while secure NVRAM is on the controller card.
Check margin alignments after replacing the operator panel assembly. If margin errors are unacceptable,
corrections can only be made through software. Contact the next level of support.
✷✷✷936 Transport motor
initial lock failure
Replace the printer or call the next
level of support.
✷ ✷✷✷937 Transport motor lost
lock
✷✷ ✷939 RIP/engine
communication error
Service tertiary light patterns—printhead, transport motor, or RIP/engine communication
error (94x)
Description/action
✷ ✷ Zero signal for fuser control has failed on LVPS.
✷ 940 Replace the LVPS/HVPS. See “LVPS/HVPS removal”
on page 4-19.
Service tertiary light patterns—NVRAM failure (95x)
Description/action
✷ ✷ ✷ When this secondary code is received, one of the following tertiary
light patterns is available.
✷ 950 Secure EEPROM
data does not match
NVRAM.
Check the connectors for the
operator panel.
Replace the operator panel, if
necessary.

failure
✷✷952 NVRAM CRC failure
✷✷ 954 NVRAM chip failure
✷✷✷955 Code ROM or
NAND failed CRC
Check the connectors for the
controller card.
Replace controller card, if
necessary.

✷ ✷✷✷957 ASIC failure
✷✷ 958 NAND failure
✷✷ ✷959 SRAM failure
Service tertiary light patterns—printhead, transport motor, or RIP/engine communication
error (93x)
