communications error
Replace the controller card. See “Controller
card removal” on page 4-17.
✷✷
4✷ 10✷ 940 Zero crossing failure • Check the connections on the LVPS card.
• Replace the LVPS. See “LVPS/HVPS
removal” on page 4-19.
✷✷
5✷ 10✷ 950 Controller card
failure—Data mismatch
between secure EEPROM
and NVRAM
If either the operator panel or controller card
were replaced proceeding the error message,
then either an incorrect card was installed or
the printer was improperly powered on.
Note: The controller card and operator panel
cannot be replaced at the same time without a
POR in between. Printer settings on each FRU
are obtained from the other. The settings are
lost if both are installed and powered on at the
same time.
