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 discon-
nected) before removing the Main Cover for service. In the event that it is neces-
sary to troubleshoot the unit with the Main Cover removed, with AC power sup-
plied, 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.
