This will take you to the Devices and Printers dialogue. We will be exploring the following steps with the printers listed in this dialogue:

  1. Printer Queue
    1. Double-click on a printer displayed under "Printers"
      • May need to double-click the title to display the printers
    2. A small window will pop up
    3. Make sure there are no jobs in queue in that window
      • Will show a document under "Document Name" and may have a status as "Pending" or "Error"
    4. If there are jobs in queue, select "Printer" at the top left and click on "Cancel All Documents"
    5. After you have checked and cleared the queue, please close the small window
    6. Repeat steps 1-5 for each printer under "Printers"
  2. Unused/Old Printers
    1. Right click on the device
    2. Select Remove Device from the context menu
    3. Select OK
    4. 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
  3. Current Printers
    • We will now be investigating the port assignment associated with each of your current devices. Certain port assignments will interfere with the proper connection of the Silhouette cutting machine. Be sure to repeat these steps with each device listed.
    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):
      • Please note the assignment currently in place
      • 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
      • Select the Apply option
      • Select the OK option
      • 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
    • 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. 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 Test Software Connection. If a Software Connection is not established, please proceed to the Assessing Hardware Failure section

If you have reached this step, it is likely that another printer is causing a USB conflict with the Silhouette cutting machine.

To resolve this conflict with another connected printer (that is directly connected to your computer via USB cable), 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 in order to avoid any associated USB conflicts. We can recommend as a temporary measure that any WiFi connected printer can be assigned to a Static IP Address. This typically resolves any USB conflicts.

If you have previously been able to connect to your machine through the software, you may attempt to try another USB port on your computer and/or another USB cable that is proven to work with other devices.

If you have tried this and are still unable to connect to your machine, please email our customer support team for further assistance at support@silhouetteamerica.com.
