Summary: | To inhibit double-sided printing when a fan of an ejection unit removably attached to an image forming apparatus fails.SOLUTION: An image forming apparatus 1 comprises: both sides inversion means 180 that inverts a sheet for forming images on both side of the sheet; a first inversion guide 172 into which the sheet is temporarily inserted by a both sides inversion means; a first tray 160 to which the sheet is ejected; an attachment part 1b to which an ejection unit 2 is removably attached; and a control section 200. The ejection unit has a second tray 161 to which a sheet is ejected, a second inversion guide 170 into which the sheet is temporarily inserted by the both sides inversion means, and a fan 171 that blows air to the second inversion guide. When the fan fails, the control section inhibits ejection of the sheet to the second tray and inhibits double-sided printing forming images on both sides of the sheet.SELECTED DRAWING: Figure 4
【課題】画像形成装置に取り外し可能に取り付けられた排出ユニットのファンが故障した場合に両面印刷を禁止する。【解決手段】シートの両面へ画像を形成するためにシートを反転する両面反転手段180と、両面反転手段によりシートが一時的に入り込む第一反転ガイド172と、シートが排出される第一トレイ160と、排出ユニット2が取り外し可能に取り付けられた取り付け部1bと、制御部200と、を備える画像形成装置1であって、排出ユニットは、シートが排出される第二トレイ161と、両面反転手段によりシートが一時的に入り込む第二反転ガイド170と、第二反転ガイドへ空気を送風するファン171と、を有し、制御部は、ファンが故障した場合、第二トレイへのシートの排出を禁止し、且つ、シートの両面へ画像を形成する両面印刷を禁止する。【選択図】図4 |
