Brother MFC-J491DW Product Safety Guide

CAUTION
Put your product on a flat, level, stable surface (such as a desk), that is free from vibration
and shocks. Put the product near a telephone socket (MFC models only) and a standard
grounded electrical socket or a standard electrical socket (for Taiwan).
DO NOT place this product on an unstable cart, stand, or table, particularly if children are
expected to be near the product. The product is heavy and may fall, causing injury to you or
others and serious damage to the product. For the products with scanning functionality, there
is an added risk of injury if the scanner glass should break.
Avoid placing your product in a busy area. If you must place it in a busy area, ensure that the
product is in a safe location where it cannot be accidentally knocked over, which could cause
injury to you or others and serious damage to the product.
Ensure that cables and cords leading to the product are secured so as not to pose a tripping
hazard.
DO NOT place heavy objects on the product.
DO NOT place any objects around the product. Such objects block the access to the electrical
socket in case of emergency. It is important that the product can be unplugged whenever
needed.
IMPORTANT
• DO NOT place your product next to devices that contain magnets or generate magnetic
fields. Doing so may interfere with the operation of the product, causing print quality
problems.
• DO NOT place the product on any tilted/slanted surface. DO NOT tip the product after ink
cartridges are installed. Doing so may cause ink spillage and internal damage to the
product.
• DO NOT place your product next to sources of interference, such as speakers or the base
units of non-Brother cordless telephones. Doing so may interfere with the operation of the
product's electronic components.
• DO NOT place anything in front of the product that will block printed pages or received faxes
