IMPORTANT SAFETY NOTICES PREVENTION OF PHYSICAL INJURY 1. Before disassembling or assembling parts of the copier and peripherals, make sure that the copier power cord is unplugged. 2. The wall outlet should be near the copier and easily accessible. 3. Note that some components of the copier and the paper tray unit are supplied with electrical voltage even if the main switch is turned off.
Page 25
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS 1. The copier and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models. - CAUTION - The RAM board on the main control board has a lithium battery which can explode if replaced incorrectly.
