If the Printer Makes a Strange Sound
Cause Corrective Action
The printer makes a sound during
operation.
The following sounds do not indicate a problem with the printer .
• There is a sound of vacuum from the Platen
T o prevent paper from rising, paper is held against the Platen by
suction from V acuum holes under it.
• There is a sound when a dif ferent size of paper is used and when
the Carriage goes from side to side
This may happen especially when using B0 or 44-inch paper .
When paper of a dif ferent size is used, a valve is automatically
activated to switch the area for paper suction, which may make a
sound. This mechanism prevents vacuum from V acuum holes where
there is no paper .
In addition, ink is ejected in sync with the movement of the Carriage
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.
