Part 1: Safety and Precautions BJC-50 2.1.2 Automatically capping When the power is switched off with the POWER button, the printer automatically caps the nozzle section of the BJ cartridge to protect itself and prevent ink leakage. If you unplug the DC plug by mistake and cut off the power supply to the printer, plug the DC plug back in, start up the printer normally, then switch off the power with the POWER button. If the nozzle section is not capped, it may clog at the nozzles due to ink drying, or the ink may leak from the nozzles. 2.1.3 When not using the printer Even when not using the printer, leave the BJ cartridge installed in the printer or store it in the cartridge container. Do the same when carrying, shipping or storing the printer. If you remove the BJ cartridge from the printer and leave it as it is, foreign matters may stick or dry ink may clog the nozzle, making it impossible to use the BJ cartridge. 2.1.4 Ink conductivity The ink in the BJ cartridge is electrically conductive. If it leaks onto a mechanical section, mop it up with a damp paper towel or the like. If it leaks onto an electrical section, mop it up completely with tissue paper or the like. Especially, if the ink enters as far as to the IC chip of the PCB and it is hard to wipe off completely, a new PCB should be used. If the Universal adapter is connected to the printer with ink leaked, this may harm the electrical section. Never switch the power on if there has been a leak. 1-6

2.1.2 Automatically capping
When the power is switched off with the
POWER
button, the printer automatically
caps the nozzle section of the BJ cartridge to protect itself and prevent ink leakage.
If you unplug the DC plug by mistake and cut off the power supply to the printer,
plug the DC plug back in, start up the printer normally, then switch off the power
with the
POWER
button.
If the nozzle section is not capped, it may clog at the nozzles due to ink
drying, or the ink may leak from the nozzles.
2.1.3 When not using the printer
Even when not using the printer, leave the BJ cartridge installed in the printer or
store it in the cartridge container.
Do the same when carrying, shipping or storing the printer.
If you remove the BJ cartridge from the printer and leave it as it is, foreign
matters may stick or dry ink may clog the nozzle, making it impossible to
use the BJ cartridge.
2.1.4 Ink conductivity
The ink in the BJ cartridge is electrically conductive.
If it leaks onto a mechanical
section, mop it up with a damp paper towel or the like.
If it leaks onto an electrical
section, mop it up completely with tissue paper or the like.
Especially, if the ink
enters as far as to the IC chip of the PCB and it is hard to wipe off completely, a new
PCB should be used.
If the Universal adapter is connected to the printer with ink leaked, this
may harm the electrical section.
Never switch the power on if there has
been a leak.
