3-5 When Not in Use for a Prolonged Period
Important Points to Observe
When the machine is not in use for a prolonged period, be sure to observe the following important points.
Keep the Main Power Switched On at All Times
When the main power is on, the machine performs cleaning of the print heads automatically to match the ambient
temperature and humidity (self-cleaning feature). Leaving the main power switched off may result in hardening of the
ink, clogging of the print heads, or other malfunction. Leave the main power switched on even when the machine is
not in use. When circumstances compel you to switch off the main power, first consult your authorized Roland DG
Corp. dealer.
Also, if a power outage or the like causes the main power to go off, switch the main power on again as soon as power
is restored. Then repeat cleaning and printing tests until dot drop-out has been eliminated. If this does not resolve the
problem, contact your authorized Roland DG Corp. dealer.
Keep at a Constant Temperature and Relative Humidity
Even when the machine is not in use, keep it at a temperature of 5 to 40˚C (41 to 104˚F) and a relative humidity of 20
to 80% (with no condensation). Temperatures that are too high may degrade the ink and cause malfunction.
Once a Week, Check the Amount of Ink and Maintenance Liquid Remaining
Self-cleaning uses up ink and maintenance liquid. If either one runs out completely, self-cleaning cannot be per-
formed, which may result in clogging of the print heads or other malfunction. Check the amount remaining in the
cartridges at least once a week. When the remaining amount displayed at the [INK REMAINING] menu is flashing, it
means that the cartridge will become empty within a week. Replace the cartridge promptly.

If a message appears
When the machine has been out of use for some time, if the message shown below remains displayed on the screen
and a warning beep sounds, it means that ink or maintenance liquid has run out completely, and self-cleaning cannot
be performed. Take action promptly. Failure to do so may result in clogging of the print heads or other malfunction.
