Beep pattern
12 short beeps
• Users cannot mute the beeping sound of alert the machine is currently making. When the machine
is making the beeping sound to alert users of a paper jam or toner request, if the machine's covers
are repeatedly opened and closed within a short space of time, the beeping sound might continue
even after normal status has resumed.
• You can change the sound type and volume. For details about Sound, see "General Features",
Device Management.

The status of the machine is indicated by the indicator lamps on the control panel, the status icons, and
messages that appear. This section describes the location of the indicator lamp for the [Check Status]
