Image forming apparatus and non-transitory computer readable medium
An image forming apparatus includes a memory and a processor configured to, when humidity detected by a humidity sensor is equal to or above a preset value with paper sheets stacked in a paper sheet holder being fed to an image forming unit, perform control to set a separation operation time used to separate in a separation operation a single paper sheet from multiple paper sheets stacked in the paper sheet holder to be longer than the separation operation time used when the detected humidity is lower than the preset value.
1. An image forming apparatus comprising:
a memory; and
a processor configured to
when humidity detected by a humidity sensor is equal to or above a preset value with paper sheets stacked in a paper sheet holder being fed to an image forming unit, perform control to set a separation operation time used to separate in a separation operation a single paper sheet from a plurality of paper sheets stacked in the paper sheet holder to be longer than the separation operation time used when the detected humidity is lower than the preset value.
2. The image forming apparatus according to claim 1 ,
wherein when the single sheet is to be separated from the sheets stacked in the paper sheet holder in the separation operation, the single paper sheet is separated from the paper sheets by sucking and picking up the single paper sheet in a blowing state in which a blower blows air to the sheets, and
wherein the processor is configured to, when the humidity detected by the humidity sensor is equal to or above the preset value, perform control to lengthen the separation operation time by setting a sheet feeding time interval to be longer in paper feeding.
3. The image forming apparatus according to claim 2 , wherein the processor is configured to perform control to set the sheet feeding time interval to be longer in the paper feeding as a length of the fed sheets in a transport direction of the sheets is longer.
4. The image forming apparatus according to claim 2 , wherein the processor is configured to perform control to set the sheet feeding time interval to be longer in the paper feeding as a weight of the fed sheet per unit area is heavier.
5. The image forming apparatus according to claim 2 , wherein the processor is configured to perform control to set the sheet feeding time interval to be longer in the paper feeding if the sheet to be fed has a paper quality that is more subject to overlapping sheet feed.
6. A non-transitory computer readable medium storing a program causing a computer to execute a process for forming an image, the process comprising:
when humidity detected by a humidity sensor is equal to or above a preset value with paper sheets stacked in a paper sheet holder being fed to an image forming unit, performing control to set a separation operation time used to separate in a separation operation a single paper sheet from a plurality of paper sheets stacked in the paper sheet holder to be longer than the separation operation time used when the detected humidity is lower than the preset value.
7. An image forming apparatus comprising:
means for storing data; and
means for, when humidity detected by a humidity sensor is equal to or above a preset value with paper sheets stacked in a paper sheet holder being fed to an image forming unit, performing control to set a separation operation time used to separate in a separation operation a single paper sheet from a plurality of paper sheets stacked in the paper sheet holder to be longer than the separation operation time used when the detected humidity is lower than the preset value.
