    1. Right click on the device
    2. Select the Printer Properties option (not simply Properties)
    3. Select the Ports tab
    4. If the printer is assigned to a USB## or WSD port (checked box is next to USB### or WSD):
      1. Please note the assignment currently in place
      2. Scroll through the list of ports and select the FILE option
        • If you cannot select the FILE option:
          1. Select the General tab
          2. Select the Change Properties button
          3. Allow changes to be made
      3. Select the Apply option

      5. Watch the Devices and Printers dialogue to ensure that the device does not duplicate after the port has been changed. If the device duplicates, please note the device
    5. If the printer is assigned to a port other than USB### or WSD Port please proceed to examine each of the remaining printers listed in the Devices and Printers dialogue
  4. Proceed to restart the computer
  5. Navigate to the Devices and Printers dialogue as previously directed
  6. Confirm that Unused/Old Printers that were previously removed have not reappeared
  7. Confirm that the port assignment of each Current Printer has not reverted to a USB### or WSD setting

If ANY printer has resisted removal OR any printer persists in its assignment to a USB### or WSD port, please proceed to the Driver Reassignment section.

If ALL printers have been confirmed as removed or assigned to a port OTHER than USB### or WSD, please reattempt the steps found in Testing Software Connection. If a Software Connection is not established, please proceed to the Hardware Failure section

It is likely that any noted printer is causing a USB conflict with the Silhouette cutting machine.

To alleviate this conflict with any direct cable (USB) connected printer, please power off the Silhouette cutting machine, power on the printer, then power on the Silhouette cutting machine.

To alleviate this conflict with any WiFi connected printer, we would advise that you contact your printer manufacturer and request assistance in the reassignment of the port associated with any noted printers, to avoid any associated USB conflicts. We can recommend that any WiFi connected printer be assigned to a Static IP Address. This typically resolves any USB conflicts.

If a Hardware Connection has previously been established, then a hardware failure is unlikely. If a Basic Hardware Connection has been established it is unlikely that the replacement of USB cable or machine will resolve the present concern. If a Basic Hardware Connection has been established, we would advise reviewing, again, the information found in the Firmware/Software Version and Interfering Connections sections.

If a Hardware Connection has not been established, there are 3 potential points of conflicts:

  1. USB Port Failure
  2. USB Cable Failure
  3. Machine Failure

To confirm that the issue is not due to (1) USB Port Failure, please perform the Testing Hardware Connection steps utilizing USB ports on the opposite side (front/back, right/left) of the connected computer.

To confirm that the issue is not due to (2) USB Cable Failure, please perform the Testing Hardware Connection steps utilizing a similar, tested, USB Cable.

If both steps above have been performed, and a Hardware Connection is still not established, it can be presumed that the Silhouette cutting machine has experienced a (3) Machine Failure. To confirm machine failure, and to discuss further options, please email us at customer support.
