Airflow

The printer uses two fans to cool its internal parts. Be sure that you do not block
the air vents. Lack of correct cooling and ventilation can cause printer failures and
improper operation.

Declaration of product noise emission values

The following tables show the noise emission values for the 4247 Printer.
Notes:
1. LWAd is the declared sound power emission level for a production series of
2. <LpA>m is the mean value of the space-averaged sound pressure emission
3. The principle printer configuration used to measure the noise emission levels
All measurements are made in accordance with International Organization for
Standardization (ISO) 7779 and reported in conformance with the International
Organization for Standardization (ISO) 9296.

The Parallel Interface

The 4247 Printer supports the Parallel Printer Interface. A single, 36-pin connector
is mounted on the adapter card.
Attach the PC-parallel interface to the host by using one of the following cables:
v Standard PC parallel printer cable, up to 1.8 m (6 ft) in length
v 1284 Bidirectional parallel printer cable, up to 4.57 m (15 ft) in length
