Flatbed / ICC card NVRAM

complete flatbed assembly from another machine will result in a 950.10 NVRAM mismatch error.

RIP board/operator panel replacement

This procedure should only be followed if both the RIP board and operator panel fail. If you only need to replace
one of the FRUs follow the startup procedure described in the FRU's removal procedure.
CAUTION - POTENTIAL INJURY: There is danger of explosion if a lithium battery is incorrectly
replaced. Replace it only with the same or an equivalent type of lithium battery. Do not recharge,
disassemble, or incinerate a lithium battery. Discard used batteries according to the manufacturer's
instructions and local regulations.
Warning: If the operator panel and the RIP board are being replaced at the same time, replace the parts in this
order to avoid damage to the machine.

motor and fans shut down, and the machine is quiet.
4.
After installing the new operator panel, start the printer in to diagnostics mode, and allow the printer to go
through a complete startup cycle and the display to go to Ready.

machine, and start it up. After the machine startup, shut down the machine, and install the new RIP card.
