Declaration of Product Noise Emission Values
The following tables show the noise emission values 4247 Model Z03.
Table 30. Sound emission levels in the Fast Draft Print Mode
Sound Emission Category Operating Idling
LWAd (1 bel = 10 decibels) 7.4 bels 5.1 bels
<LpA>m (bystander positions) 59.7 decibels 36 decibels
Notes:
1. LWAd is the declared sound power emission level for a production series of
machines.
2. <LpA>m is the mean value of the space-averaged sound pressure emission
levels at the one-meter position.
3. The principle printer configuration used to measure the noise emission levels
was:
v
Fast Draft Print Quality mode
v Table top operation
v Without Quiet mode
All measurements are made in accordance with the American National Standards
Institute (ANSI) S12.10 and reported in conformance with the International
