Abstract
An imaging system includes a housing to define a housing space, a collection device to collect fine particles in the housing space, a detection device to detect a collection performance of the collection device, and a cleaning device to clean the collection device.
Claims17
An imaging system comprising:
- a housing to define a housing space;
- a collection device to collect fine particles in the housing space, wherein the collection device includes a charging device and a filter downstream of the charging device in a direction of an air flow passage that directs a portion of the fine particles to collect as a soiling on the charging device;
- a detection device to detect a collection performance of the collection device based in part on a measurement of the soiling on the charging device;
- and
- a cleaning device to clean the collection device based on the collection performance.
2 more elements
An imaging system comprising:
- a housing to define a housing space;
- a second collection device including a second filter coupled to a second air flow passage;
- a switching device to selectively switch between the first air flow passage and the second air flow passage to form a selected air flow passage which communicates an inside of the housing with an outside of the housing, wherein the switching device is to switch to the second air flow passage when a collection performance of the first collection device is less than a threshold performance;
- and
- a cleaning device to clean the first collection device.
2 more elements
An imaging system comprising:
- a housing to define a housing space;
- a collection device to collect fine particles in the housing space, the collection device including a charging device to charge the fine particles and a filter to collect the fine particles having been charged, wherein the fine particles collected form a soiling on the filter;
- a fixing device;
- and
- a print controller to:
- compare a detected collection performance of the filter with a threshold performance for the filter;
- and
- reduce a highest temperature of the fixing device when the detected collection performance is less than the threshold performance.
