Ricoh Pro TF6251 Operating Instructions Manual page 38

3. Basic Operations
• Do not unplug the power cord plug. If the power cord plug is unplugged, the negative pressure
adjustment function does not work, which may cause ink to leak from the nozzles.
• Confirm that the carriage is returned to the maintenance station position before turning off the
power. If you turn off the power before the carriage returns to the maintenance station position, the
print heads will get dry, which may cause nozzle clogging.
• Do not turn off the power during printing. Otherwise, the carriage may not return to the
maintenance station.
• If pressing any of the emergency buttons, the main power switch turns off forcibly. After pressing the
stand-by button on the control section on the front part of the machine, release the emergency stop
button. After releasing the emergency stop button, press the power-on button on the control section
on the front part of the machine and then restart the software. Do not leave the emergency stop
button pressed. Ink leakage may occur.
