If the Printer makes a strange sound If the Printer makes a strange sound If the Printer Makes a Strange Sound The following sounds do not indicate a problem with the printer. • There is a sound of vacuum from the Platen To prevent paper from rising, paper is held against the Platen by suction from Vacuum holes under it. • There is a sound when a different 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 different 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 Vacuum 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. • Roll paper makes a uttering sound during printing There may be a uttering sound when large paper is advanced. • If you suddenly hear the tone for cleaning operations At regular intervals, for printer maintenance, cleaning operations will begin automatically, even if the printer is in Sleep mode. • If you suddenly hear the tone for ink agitation At regular intervals, to ensure optimal printing quality, the ink is agitated automatically, even if the printer is in Sleep mode.(*1) The ink is also agitated automatically under the following conditions.
