3.2 Service Mode of Printer Driver
There are certain printer driver control functions, described below, that are, in
principle, hidden from the end user. These service mode functions, which must be
used with caution, are provided for service purposes only.
See
"Part 3: 3.3.2 Service mode of printer driver" (page 3-18)
for details.
3.3 Protecting the Power Supply
The power supply for the BJC-7100 printer consists of an AC adapter and a power supply
circuit on the logic board. Provided the AC supply is connected, the printer power supply
is live whether or not the power is set ON or OFF using the
POWER
button.
Always unplug the AC adapter from the power outlet before connecting it to or
disconnecting it from the printer. Ignoring this warning can result in damage and
failure of the printer power supply.
When moving the carriage by hand when, for example, manually capping the
ink nozzles or releasing the carriage lock, do so slowly while paying attention
to the operation of the carriage motor; the back electromotive force generated
by moving the carriage horizontally may damage the motor control board.
If it is necessary to move the carriage horizontally fairly frequently, such
as when replacing or adjusting the carriage, temporarily disconnect the
carriage motor connector from the control board.
