18 AP-74700 – Rev. 1.0 – 10/03/2008
2.2 CPU ERRORS
These errors can appear when internally the machine detected an illegal software command in the central
microprocessor-circuitry inside the mainboard.
This can happen due to:
• Illegal header-commands might be sent from the rip-computer Æ Make sure the rip is always updated to
the latest version!
Also make sure the latest printer-driver from the Mutoh-website!
If the problem is still occurring:
o Try another rip computer or use a pre-ripped (demo-) file provided by Mutoh.
o Try to rip to a different (analog) Mutoh-printer, whenever available.
o Try to rip an internal job, e.g. print a palette or distance adjust test
• A power drop or spike on the power supply Æ Reboot machine
Check if the problem reoccurs. Also always check for a good, stable power connection + properly
grounded.
• Generally when a permanent-occurring CPU-error appears on your LCD display, every time after
restarting the machine several times, there are possible clues:
• Install always the latest and correct firmware-version!
SX for new-generation RoHS-compliant mainboards
SP for the previous non-RoHS-compliant mainboards
o The onboard offline-memory may be corrupt. Reset the NVRAM and re-insert all the parameters
manually (not with a backup-flashcard or via Ethernet) via the LCD Display. Manual input avoids
copying corrupted data back.
o With the installed firmware – Always install the correct and the latest firmware version!
o Try with a different Mutoh memory-module.
o If this error still reoccurs after these actions, replacing the mainboard and re-inserting the parameters
manually is the last solution. Same reason again, why inserting parameters manually, is to avoid
copying possible NVRAM data to the new mainboard.
• For printers equipped with an older non-RoHs mainboard can, you can also try the following procedure:
o Load the Falcon II v1.26 firmware
o Load directly afterwards, back the latest firmware applicable for your machine
o Re-insert the parameters via the LCD display (to avoid copying corrupt parameters)
o Test if the machine is working properly and try to print
o If the problem still persists after this, the mainboard might need to be replaced
• For printer equipped with a RoHs-mainboard (Revision A or later), this described test is not applicable as
no Falcon II machines exist with these boards. So just make sure you use the latest firmware-version!
Some more specific CPU errors:

Data boundary exception errors. Trouble occurred in the data boundary in its internal memory.
• Make sure you us an Original Mutoh Memory Module ONLY.
