Part 1: Safety and Precautions BJC-6000 2.1.2 Automatic capping When the printer is turned off with the POWER button, it automatically caps the BJ cartridge's nozzles to protect them as well as to prevent ink leakage. If the AC cable is unplugged from a wall outlet before the printer is turned off with the POWER button, the nozzles will not be automatically capped. In this case, plug in the AC cable again, turn on the printer, and then turn it off with the POWER button. The nozzles will be automatically capped. CAUTION If the nozzles are not capped, ink may dry out and clog the nozzles or leak from the cartridge. 2.1.3 When not using the printer The BJ cartridge may be either left installed in the printer or stored in the cartridge container. This also applies when carrying, transporting, or storing the printer. CAUTION If the BJ cartridge is left in open air, out of the printer or cartridge container, foreign matter or dried ink may clog the nozzles, resulting in poor print quality. 2.1.4 Ink's electroconductivity The ink in the BJ cartridge conducts electricity. If ink is spilt in the printer's mechanical parts, use a dampened paper towel to wipe clean. If ink is spilt onto the printer's electrical components, use tissue paper to wipe clean. If ink gets under an IC chip on the control board and cannot be removed thoroughly, replace the control board with a new one. Never plug in the printer if its' electric circuitry is in contact with spilt ink. CAUTION Otherwise the electric circuitry could be damaged. 1-6

2.1.2 Automatic capping
When the printer is turned off with the
POWER
button
, it automatically caps the BJ
cartridge's nozzles to protect them as well as to prevent ink leakage.
If the AC cable is
unplugged from a wall outlet before the printer is turned off with the
POWER
button,
the nozzles will not be automatically capped.
In this case, plug in the AC cable again,
turn on the printer, and then turn it off with the
POWER
button
.
The nozzles will be
automatically capped.
If the nozzles are not capped, ink may dry out and clog the nozzles or leak
from the cartridge.
2.1.3 When not using the printer
The BJ cartridge may be either left installed in the printer or stored in the cartridge
container.
This also applies when carrying, transporting, or storing the printer.
If the BJ cartridge is left in open air, out of the printer or cartridge
container, foreign matter or dried ink may clog the nozzles, resulting in
poor print quality.
2.1.4 Ink's electroconductivity
The ink in the BJ cartridge conducts electricity.
If ink is spilt in the printer's
mechanical parts, use a dampened paper towel to wipe clean.
If ink is spilt onto the
printer's electrical components, use tissue paper to wipe clean.
If ink gets under an
IC chip on the control board and cannot be removed thoroughly, replace the control
board with a new one.
Never plug in the printer if its' electric circuitry is in contact with spilt ink.
Otherwise the electric circuitry could be damaged.
