Service Caution - Oki OKIOFFICE44 Service Manual

Service Caution

The High Voltage Power Supply Unit in the OKIOFFICE 44 is mounted vertically on the
left side of the unit, with the land side fully exposed. This board develops voltages of
up to 1300 VDC as part of the normal printing process.
OKIDATA recommends that the unit be powered OFF (AC supply cord disconnected)
before removing the Main Cover for service. In the event that it is necessary to
troubleshoot the unit with the Main Cover removed, with AC power supplied, please
take every caution to avoid touching the exposed circuitry of the High Voltage Power
Supply Unit. To do so accidentally can result in a shock hazard.
