dC335, dC361
General Procedures/Information
The ink melt plate heaters only have options for On and Off as listed in Table 2 .
NOTE: The ink melt heater Setpoint Mode for On is displayed as 120 degrees C. This is a tar-
get temperature only. The heater will turn on for a few seconds each time it is activated. It is not
intended to reach 120 degrees. Due to the risk of overflow if the ink melt is continuously acti-
vated the software will ignore the command.
Procedure
1. Enter service mode, GP 1 .
2. Select the Diagnostics tab.
3. Select dC335 Heater Monitor and Exerciser.
The screen displays a blank graph with options to select the required component.
4. Select a component from the menu at the bottom left of the screen.
As each component is selected the corresponding buttons will change to match the
options for that component.
NOTE: If the setpoint mode of any of the printhead heaters (reservoir, left jetstack or right jet-
stack) is changed, the other two heaters will change to the same setpoint mode automatically.
This is to ensure that the printhead is not subjected to undue stress due to temperature varia-
tion between the different heaters.
5. Select the component and options required.
6. Select the Graph button
• The graph will display a trace indicating the temperature change in real time.
• The green line indicates the time.
• The blue line indicates the current temperature.

dC361 NVM Save and Restore
Purpose
To restore the NVM parameters of the machine to their previous values following a service
action; i.e. NVM expansion, Single Board Controller (SBC) Printed Wiring Board (PWB)
replacement, or any others that would necessitate a full NVM initialization. It can also be used
to recover a machine‘s NVM values to a recent service call, in the event that a complete NVM
failure occurred. As an additional tool, the ability to copy files between the hard drive and a
USB drive is provided.
The NVM save to hard disk must be performed at the first service call and whenever the sys-
tem software is changed.
This procedure will save and restore only the SBC, IIT and IME NVM.
NOTE: After a USB flash drive is first connected to the machine a UI sceen message offering
scan to and print from USB options will display. This screen message can be closed or left
open before entering diagnostics without effecting the NVM save / restore processes. If you
choose to close the scan to and print from USB screen message it will not reappear on exit
from diagnostics. Therefore, leave this message screen open if the scan to and print from USB
options are to be required after a NVM save / restore.
Procedure
NVM Save
1. If necessary, connect the USB flash drive to the USB port on the left side of the machine.
2. Enter service mode, GP 1 .
3. Select the Adjustments tab.
4. Select dC361 NVM Save and Restore.
The screen displays the NVM data.
NOTE:
• The top entry displays the live NVM data for the machine.
• If the data has previously been saved to the hard disk these will be displayed in a list
below the live data.
• If a USB device containing NVM data is connected these will be displayed below the
hard disk data. To be recognized by the machine the USB device must be connected
at the time dC361 is started.
5. Save the NVM data.
• To save the live data to the hard disk select the live data entry and select save to
hard disk.
• To save the hard disk data to a USB device select the hard disk entry and select
save to USB device.
• To save the USB data to the hard disk select the USB entry and select save to HDD.
NOTE: Data cannot be saved or restored directly to or from the USB device to the
machine.
6. Select Close to return to the service mode window.
7. Select Call Closeout to exit service mode
