Abstract
A method for regulating dew formation on a photosensitive drum in an image forming apparatus comprises detecting the surface temperature of the photosensitive drum, detecting the internal temperature of the image forming apparatus and detecting the internal humidity of the image forming apparatus. A dew point is calculated and it is determined whether the surface temperature is higher than the dew point. If the surface temperature is lower than the dew point then the operation state one or more components within the image forming apparatus is adjusted to regulate dew formation. However, if the surface temperature remains higher than the sum of the dew point and the threshold value, normal operation is maintained.
Claims26
A method for regulating dew formation on a photosensitive drum in an image forming apparatus, comprising:
- detecting the surface temperature of the photosensitive drum;
- detecting the internal temperature of the image forming apparatus;
- detecting the internal humidity of the image forming apparatus;
- calculating a dew point;
- determining if the surface temperature is higher than the dew point;
- and
- if the surface temperature is lower than the dew point, adjusting an operation state of one or more components within the image forming apparatus to regulate dew formation.
A system for regulating dew formation inside an image forming apparatus, comprising:
- a photosensitive drum;
- a first detection sensor coupled to the photosensitive drum for detecting a temperature of the surface of the photosensitive drum;
- and
- a second detection sensor positioned near the photosensitive drum for detecting the internal humidity and internal temperature of the image forming apparatus.
