2. Capping
The printer will perform the capping operation when printing has finished or during standby due to errors, in order to protect the printhead and avoid ink
leakage.
If the power cord is accidentally unplugged, turn the power button off, reconnect the power cord, and turn the power button on to confirm that the printer
starts up properly and changes to the "Online" or "Offline" state, then power off the printer using the power button.
Improper 'capping' may cause clogged printhead nozzles due to dried ink or ink leakage from the printhead.
3. When the printer is not used for a long time
Keep the printhead installed in the printer even when it is not used for an extended period of time.
If the printhead is left uninstalled, printing failure may arise from clogged nozzles due to the depositing of foreign matter or dried ink when it is reinstalled.
Even if the head remains installed, the nozzle may dry out and cause printing failure if the ink is drained for transport.
4. Conductivity of ink
The ink used in this printer is electrically conductive. If ink leaks into the mechanical unit, wipe clean with a soft, well-wrung damp cloth. If ink leaks onto
electrical units, wipe them completely using tissue paper. In particular, if ink penetrates beneath the IC chips on the logic board and you cannot remove it
completely, replace with a new logic board.
If electrical units are powered on when ink has leaked, the units may be damaged.
Never connect the power cord when ink has leaked on the electrical units.
1.7.2.2 Ink Tank
0009-1486
1. Opening the ink tank
Do not open the ink tank until ready to use.
When installing the ink tank, shake it slowly 7 to 8 times before opening the seal. Otherwise, the ink ingredients may precipitate and reduce the print quality.
To prevent foreign matter from entering the ink supply unit, install the opened Ink tank mmediately.
2. Handling the ink tank
To prevent foreign matter from entering the ink flow path and causing ink suction and printing problems, never touch the ink port or terminal section of
the ink tank.
When you press down the ink tank cover, the needle enters the ink supply unit, which allows ink to flow between the printer and ink tank.
Do not raise or lower the ink tank lever, except when replacing the ink tank.
