(23) A head/carriage unit is assigned a property code that represents the properties unique to that
head/carriage unit. The property code is printed on head property labels--bar code label and QR
code label, each of which is attached to the lower cover and carriage-head flat cable,
respectively.
When you remove the head/carriage unit and store it separately from the machine, remove the
property label (bar code label) from the lower cover and store it together with the head/carriage
unit.
If you replace the head/carriage unit, attach the property label (bar code label) that comes with
the new head/carriage unit to the lower cover as shown below.
