4.2.2 Carriage unit

When the cartridges are installed and the power is OFF, the carriage is normally
locked in the capping position. The locking mechanism is in the purge unit and
prevents the carriage moving from the capping position exposing and potentially
damaging the print head while the printer is being shipped or moved.
When servicing the printer, you can manually release this lock using the following
procedure.
