When Not in Use for a Prolonged Period
- Switch on the sub power once a month.
[PRESS THE POWER KEY TO CLEAN] message appears once a month.
- 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.
Temperatures that are too low may cause the ink to freeze and damage the heads.
Explain following items in reference to the Setup Guide.
When Transferring the Unit
VS-640/540/420/300 is transported with the ink filled. The ink pressure applied from the ink cartridges closes
the inner valve of the ink damper. So that, you do not have to worry about ink dripping during transporting.
When the machine has to be tilted, always keep the cartridge slot side upper than the print head side.
