Cause or Overview
The printer may not be making reliable contact with the docking station cradle contacts
If a QLn220, QLn320, or QLn420 series mobile printer with on-board Ethernet support is not being recognized on the wired network when placed into a network connected Ethernet cradle, insure that the cradle contacts on the underside of the printer are free of any residue. After removing the docking cradle access cover to expose the cradle contacts, make sure that no glue residue remains on any of the gold contacts. If some residue does remain, remove it with a soft cloth or alcohol swab before inserting the printer into the Ethernet cradle.
