Needs for installation:
Reliable Power source/outlet. Consider using a UPS if your area's power is unreliable.
Temperature and Humidity
Set up an electronic thermo hygrometer near the machine to monitor ambient temperature and
•
humidity.
• The target ranges for temperature and humidity are 15°C to 32°C (59°F to 90°F) and 45% to 80% RH
(with no condensation).
The machine will display an alert if either temperature or humidity is out of range.
•
• If the ambient temperature or humidity is out of range, a small sensor inside the carriage will detect
this condition and shut down the machine. (This temperature/humidity sensor inside the carriage is
not a service part.)
Humidity
• Ambient humidity must remain more than 45% RH, regardless of temperature. If humidity falls
below 45% this can cause ink to dry faster and cause ink to clog at the print heads and in the
maintenance unit.
• If ambient humidity goes higher than 80% with condensation, regardless of temperature, the ink
may be easily oozed (for example, because the media is damp).
Temperature
• If temperature falls lower than 15°C (59°F) this will interfere with ink ejection (due to higher
viscosity) at the print heads and can lead to ink scattering due to deflection and result in poor
images. The increase in viscosity at low temperature will also cause problems with ink pumping and
operation of the maintenance unit. The slower flow rate of the ink, due to high viscosity, will also
decrease the amount of ink that reaches the print head tanks.
If temperature goes higher 32°C (90°F) this can also cause ink scattering and result in poor quality
•
images. Higher temperatures can also cause electrical components like motors, solenoids, etc. to
fail.
