Machine Doesn't Start
SYMPTOMS:
When starting the dispenser, the status acts like it's starting and after a long time, will throw an error.
This generally happens when the COM Port number for the X-Smart was changed by Windows but the Fluid Management Driver does not pick up the change and tries to keep communicating with the last known COM Port number used but doesn’t prompt the user to pick a new COM port.
If a prompt does show up while starting the dispenser, follow SECTION 1 to find the correct COM Port.
Follow the steps below to fix this issue.
SECTION 1 - Identify the COM Port number
1. Right click on the Windows Start Menu
2. Select Device Manager
3. Double click on Ports (COM & LPT), this will expand the section.
4. Locate the device named USB Serial Port (COM4), remember the number after COM. .png)
The COM number used for this example, yours will differ.
