Incorrect USB port selection
Incorrect USB Port specification is one of the most common problems. Perform a
Printer Port Test. If there is no communication between the printer and computer, it is
likely that the printer is assigned to the wrong USB COM port.
To assign the proper USB port to MelcoJet printer, click Start / Control Panel / Printers
& Faxes. From the Printers & Faxes dialog box, double click the MelcoJet driver, then
click on the Ports tab. Select the proper USB port if you know it (in this illustration, it is
USB006), then click OK. Proceed to the Printer Port Test in the Utilities window to
confirm. If you do not know which port is assigned to MelcoJet, you may have to try each
of the USB ports listed in the Ports tab dialog box until you make the proper connection.
Once all of the above problems are resolved, perform a Printer Port Test in the utilities
window to make sure the computer and MelcoJet are communicating properly.
Reinstalling the printer driver
Try reinstalling the printer driver program. Before reinstalling the driver, first uninstall
the printer driver using the Printers and Faxes utility of the Windows Control panel.
