Troubleshooting Without Error Code; Parameter & Printing Related Issues; Parameters Are Not Being Saved During Shutdown; Unstable Machine Behaviour (Cpu Errors, Machine Crashes) - MUTOH Rockhopper 3 Troubleshooting Manual

3 TROUBLESHOOTING WITHOUT ERROR
3.1 PARAMETER & PRINTING RELATED ISSUES

3.1.1 Parameters are not being saved during shutdown

Step 1 : Be assured to use the latest firmware-version
Step 2 : Check available NVRAM
Diagnostics
Free space: bytes free
Max block: largest block free (bytes)
If an error occurs, problems occur or the free space for parameters is very low (<100), proceed
to the next step
Step 3 : Go to diagnostics – and change MOD-level to 0
(MOD-level defragments internal parameters, clearing memory for additional data, can be re-
verified with Test
Step 4 : If still not ok:
a. Try to reset the parameters
b. Try to clear the NVRAM
Step 5 : If the problem still persists, the NVRAM might be damaged

3.1.2 Unstable machine behaviour (CPU errors, machine crashes)

If this behaviour still proceeds, after replacing a main-board and restoring the parameter-backup, in some
rare cases, it can happen that something inside the parameters becomes corrupt but we cannot see. This
results mostly in strange machine-behaviour (unknown cpu errors, crashes).
In that case a parameter backup should not be taken because when you restore it, you might literally
'restore the problem' on another board.
In this situation, the clearance of the NVRAM may be proceeded.
Before proceeding to this try to print out the machine setup and parameters to insert everything with the
same values afterwards.

EFORE PROCEEDING WITH THIS PROCEDURE
,
DONE YOU MIGHT LOOSE THE SETTINGS AND WILL MAKE YOUR MACHINE TOTALLY UNUSABLE
MAINBOARD REPLACEMENT IS THE ONLY OPTION
This procedure takes much more time and is more complicated (the machine doesn't know if there is ink
inside, eco ink or mid solvent ink, or cleaning, the serial number is gone, head adjustments in parameters
must be re-programmed, distance adjust, etc...). This manual programming, will take much more labour-
time... (up to a few hours)
So, in this situation, manual parameter might anyway still be useful...
