8. Maintenance
When Not Using for a Long Period of Time
If you do not use the machine for a long time, ensure the following:
Clean the internal compartments using the dedicated cleaning cartridge in advance. For the
•
cleaning method, see page 118 "Clean Internals".
Once the internal compartments are cleaned, turn the machine power off, disconnect the
•
USB cable or Ethernet cable, and then unplug it from the wall outlet.
It is recommended to print at least once a month, because the machine consumes a considerable
amount of ink for periodic maintenance and print head cleaning when turned on after a long
period of inactivity.
• If this machine is not going to be used for several days or longer at a time, disconnect its
power cord from the wall outlet.
• When disconnecting the power cord from the wall outlet, always pull the plug, not the
cord. Pulling the cord can damage the power cord. Use of damaged power cords could
result in fire or electric shock.
Be careful of the following:
The nozzles of the print heads may dry out and become clogged. To prevent this, periodically
•
print something. Even if you do not print anything, turn the machine on for a few minutes
once every 20‐25 days.
If you do not use the machine for a long period of time, always check if the nozzles are
•
clogged by printing a nozzle check test pattern. See page 99 "Nozzle Check". Clean the print
heads as necessary, and then begin printing. See page 101 "Head‐cleaning".
If you try to use the machine after it has been out of use for a long time, it may not print
•
properly even if head cleaning is carried out several times. If this is the case, carry out head
flushing. See page 102 "Head‐flushing". If the print heads are still clogged, leave the machine
for about ten minutes, and then print the nozzle check pattern. If the problem persists, turn
the machine off and leave it for at least eight hours. This should unclog the print heads.
After head cleaning is performed multiple times, clogged ink will dissolve over time, and
•
normal printing may become possible.
If there is no improvement after performing the steps above, contact authorized Roland DG
•
Corporation dealer.
