Errors and warnings are displayed by the following ways:
1) Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution are displayed on the LCD in text and
by icon.
2) Messages during printing from a computer are displayed on the printer driver Status Monitor.
3) Error codes are printed in the "operator call/service call error record" area in EEPROM information print.
Buttons valid when an operator call error occurs:
1) ON/OFF button: To turn the printer off and on again.

(3) Carriage unit replacement
When replacing the carriage unit (QM2-3897), confirm the carriage flexible cable position.
Incorrect positioning of the carriage flexible cable will cause malfunction due to contact of the cable to other parts, or
deformation of the cable itself.
(I) Carriage flexible cable position
Confirm that the carriage flexible cable is not seen in the concave-shaped space of the carriage FCC holder.
(II) Carriage FCC holder sheet position
Attach the carriage FCC holder sheet in the red rectangle-indicated position.

(4) Platen unit assembly
When replacing the platen unit (QM2-3976), confirm that the bridge sheets at the bottom of the platen unit do not curl or
bend.
Curled or bent sheets may prevent ink flow from the borderless ink absorber to the main ink absorber, causing ink leakage
from the absorbers.
Bridge sheet position:
Insert the sheets in the holes of the chassis.
