1.2 High Temperature Parts

Precautions
To prevent burns while disassembling the fax, disconnect the power
cord at least 10 minutes before starting disassembly, to allow high
temperature parts to cool down.
How to treat burns
Heat of about 122°F (50°C) or more causes burns. Also, the longer
the contact, the more severe the burn.
When treating a burn, the first minute after receiving the burn is
the most important. Cool the burn immediately with cold running
water. In the case of a serious burn, seek medical attention
immediately.
The temperatures of the parts shown below become more than 50°C during
operation.
Be Careful not to burn yourself on any of these parts during servicing.
