Display: 49.XXXXX ERROR To continue turn off then on
Description: A critical firmware error has occurred.
Remedy: 1. Turn the device off, and then turn the device on. 2. Check the latest firmware image version. If the latest firmware image version is newer than the one installed on the device, upgrade the device. 3. Try printing a job from a different software program. If the job prints, go back to the first program and try printing a different file. If the message appears only with a certain software program or print job, then the error is in the software program and not in the device. If the job fails to print using a different software program, then turn off the device and disconnect all cables that connect the device to the network or to a computer. 4. Remove any DIMMs and EIO cards, and then turn the device on. 5. If, after removing DIMMs and EIO cards, the device behaves normally, turn off the device and reinstall DIMMs and EIO cards one-by-one, turning off the device off and then on again each time you reinstall a DIMM or EIO card. If a certain DIMM or EIO card causes the message to reappear, replace the DIMM or EIO card. 6. Reconnect all cables that connect the device to the network or to a computer. 7. If the message persists, replace the formatter
