Appendix Environmental Conditions Temperature and humidity Acoustic noise 83 For operation When using only battery for power supply When using battery and AC adapter for power supply Temperature: 0 to 45°C {32 to 113°F} Humidity: 10 to 90% RH (except for paper) Temperature: 0 to 40°C {32 to 104°F} Humidity: 10 to 90% RH (except for paper) For print quality When using only battery for power supply When using battery and AC adapter for power supply Temperature: 5 to 45°C {41 to 113°F} Humidity: 10 to 90% RH Temperature: 5 to 40°C {41 to 104°F} Humidity: 10 to 90% RH For battery charging Temperature: 0 to 40°C {32 to 104°F} Humidity: 10 to 90% RH For storage Temperature:
-25 to 70°C {-13 to 158°F} Storage time: 120 hours During operation Approximately 53 dB (bystander position) (including auto- cutting operation) Note: The values above are measured in the Epson evaluation condition. Acoustic noise differs depending on the paper used, print- ing contents, and the setting values, such as print speed or print density.
