Error 49 Cycle Power FFF
49 errors are possibly one of the most difficult to diagnose.
49 Indicates that a firmware error occurred that caused the processor on the formatter to abort an operation.
This type of error can be caused by invalid print commands, corrupt data, or invalid operations. In some cases, electrical noise in the cable can corrupt data during transmission to the printer.
Other causes include poor quality parallel cables, poor connections, or home-grown applications.
On some occasions, the formatter is at fault, but this is usually
indicated by a 79 Service Error.
I see you state a 49FFF? any other letters or digits displayed?
Specifically 49 FFFF can be a problem if the ribbon cable from the DC controller to the interconnector board is not connected. The control panel display will also be dark.
Other 49 FFx errors can be:
NEC firmware chip error - replace the Firmware
Unsupported EDO Memory installed - Remove unsupported RAM
Fuser life test error during Boot cycle - Replace the Formatter
A Large print Job (>800 pages) or complex graphics can cause the device to quit printing. - Simplify the Print Job, lower DPI etc.,
