DOCKING CRADLE ACCESS

Note • Remove the “Docking Cradle Access” label on the bottom of

the QLn320 or 220 printers before docking the printer in the cradle.

Note • Clean the docking contacts with a Zebra cleaning pen to

remove any residue left behind by the label.

The QLn420 does not use the above label over the docking

contacts, but instead includes a plastic docking contacts cov-

er secured by two screws. Remove the screws to remove the

docking contacts cover from the printer and expose the dock-

ing contacts (as shown below).
