Note • When updating from firmware V68.16.3Z or any earlier version, users must first

update the printer to V68.18.6Z, before updating to any later versions. We also recommend

that users power cycle the printer after the update to V68.18.6Z, before moving to any later

versions.

In addition, when updating from firmware V68.18.1Z or any earlier version, we

recommend users

default the printer after updating to a later firmware version. To default the

printer, send these ZPL commands to the unit:

^XA^JUF^XZ

^XA^JUS^XZ

Wait 5 seconds after sending these command and then power cycle the printer.
