Error code 18 Problem: " MIO Not Ready " error message

Possible Cause and Solutions:



• The printer is not connected to a LAN when it's expecting to see a LAN. Terminate the port on the printer with a BNC T and two 50 ohm termination's.
• The MIO card is defective or maybe just not seated correctly. Remove the card and reseat it, try swapping with a known good card from another printer. Replace if necessary.
•Windows XP, click Start and then click Control Panel. Click Printers And Other Hardware and Printers And Faxes. In the Printers And Faxes window, from the File menu, click Server Properties, then click the Drivers tab. This shows the settings in your printer's driver. Compare the settings in this dialog box with the ideal settings in your printer's manual. If you see a discrepancy in these settings, the printer may simply need a new driver and delete old one. You can download printer drivers from the printer manufacturer's Web site.
• Get more help. Installing a new driver won't solve every printer woe, of course, so understanding Windows' built-in Help system will give you an even sharper troubleshooting edge.
