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.
Claims20
An imaging system comprising:
- a housing to define a housing space;
- a collection device to collect fine particles in the housing space;
- a cleaning device to dean the collection device.
The imaging system according to claim 16,
- wherein the collection device includes a charging device to charge the fine particles and a filter to collect the fine particles having been charged, wherein the fine particles collected from a soiling on the filter, and
- wherein the detection device includes a filter soiling measurement device to measure the soiling on the filter and to detect the collection performance based on the soiling measured.
The imaging system according to claim 16,
- wherein the collection device includes a charging device and a filter downstream of the charging device in a direction of an air flow passage to carry the fine particles, the air flow passage to direct an air flow that causes a portion of the fine particles to collect as a soiling on the charging device, and
- wherein the detection device includes a charging-device soiling measurement device to measure the soiling on the charging device so as to detect the collection performance based on the soiling measured.
The imaging system according to claim 16, comprising:
- a cleaning controller to compare the collection performance detected with a threshold performance, and to cause the cleaning device to operate when the collection performance is less than the threshold performance.
The imaging system according to claim 16, comprising:
- a fixing device;
- and
- a print controller to:
- compare the collection performance detected with a threshold performance, and
- reduce a highest temperature of the fixing device when the collection performance detected is less than the threshold performance.
