The acoustical noise emission levels for the Infoprint 3000 are as follows. Operating levels are measured during continuous running with 20-pound forms.

Table 10. Declared acoustical noise emissions for the Infoprint 3000 in accordance with ISO 9296
  Declared A-Weighted Sound Power Level, LWAd (B) Declared A-Weighted Sound Pressure Level,LpAm (dB)
Operating Idling Operating Idling
60 Hz 6.5 5.5 63 54
  1. LWAd is the statistical upper-limit A-weighted sound power level.
  2. LpAm is the mean A-weighted emission sound pressure level measured at one-meter bystander positions.
  3. 1 B = 10 dB
  4. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.
