four times.
Soft alert
An error message appears on the
control panel if there is no tray for the
selected paper size or the tray is
empty.
Five short beeps repeated
five times.
Strong alert
The printer requires user attention
because paper has jammed, the toner
needs replenishing, or other problems
have occurred.
• Beep alerts cannot be muted. If the printer's covers are opened and closed repeatedly within a
short space of time during an alert indicating a paper jam or insufficient toner, a beep alert might
continue, even after normal status has resumed.
• You can enable or disable beep alerts. For details, see:
• "General Settings", Operating Instructions. (for SP 4510DN)
