Cause Corrective Action
The printer makes a sound during
operation.
The following sounds do not indicate a problem with the printer .

the Carriage goes from side to side
When paper of a dif ferent size is used, a valve is automatically

there is no paper .

back and forth to ensure optimal ink ow . At this time, the valve
automatically switches the area for paper suction, which may make
a sound.
