    • A print job is received into a print engine having an image processor. A page of the print job is analyzed for a color gamut and for clear toner. For multi-pass print jobs, toner usage per pixel for each color of the color gamut and the clear toner is determined. Adjusted pixel values for the clear toner are calculated using a predetermined percentage. Adjusted pixel values for the color toner are calculated for each color of the color gamut based on the maximum toner limit. A first layer of the page is rendered using the adjusted pixel values. Then, the adjusted pixel values are scaled for clear toner usage based on the predetermined percentage for the clear toner on the first pass using a tone reproduction curve. Subsequent layers of the page are rendered in selected passes using only the scaled pixel values for clear toner usage.
    • 打印作业被接收到具有图像处理器的打印引擎中。 分析打印作业的页面的色域和透明调色剂。 对于多遍打印作业,确定色域中每种颜色的像素的碳粉使用量和透明调色剂。 使用预定百分比来计算透明调色剂的调整像素值。 基于最大调色剂限度,针对色域的每种颜色计算彩色调色剂的调整像素值。 使用调整后的像素值渲染页面的第一层。 然后,使用色调再现曲线,基于第一次通过中的透明调色剂的预定百分比来调整调整后的像素值用于清除调色剂使用。 页面的后续图层仅使用经缩放的像素值在所选的图像中呈现,以清除墨粉使用量。

    • An image forming apparatus includes a communication portion arranged inside a cover covering an image forming portion in the main body of the apparatus and including an antenna surface for use in establishing near field communication. The cover includes a stacking portion in its upper section. The stacking portion is configured to receive a recording medium with an image thereon, the recording medium being discharged outside the main body of the apparatus. The antenna surface faces a region of the upper section of the cover downstream in a direction of discharging the recording medium. The antenna surface at least partially faces a region of the upper section of the cover outside the stacking portion in a direction perpendicular to the direction of discharging the recording medium. The communication portion is capable of communicating with another communication portion using near field communication.

    • In general, according to one embodiment, an image forming apparatus includes a display unit, an operation input unit, a storage unit, a control unit, and an image forming unit. The operation input unit receives an operation input. The storage unit stores function restriction instruction content that disables setting and use of a predetermined function related to printing, so as to correspond to a sheet handling method after image formation. The control unit displays a setting screen for setting each function related to printing and selecting the sheet handling method on the display unit, acquires the function restriction instruction content corresponding to the selected sheet handling method from the storage unit when the sheet handling method is selected, displays the setting screen in which setting and use of the predetermined function are disabled on the display unit on the basis of the acquired function restriction instruction content, and receives print setting on the setting screen. The image forming unit is controlled by the control unit on the basis of the setting received on the setting screen and forms an image on a sheet.
    • 通常,根据一个实施例,图像形成装置包括显示单元,操作输入单元,存储单元,控制单元和图像形成单元。 操作输入单元接收操作输入。 存储单元存储禁止与打印相关的预定功能的设置和使用的功能限制指令内容,以便对应于图像形成之后的片材处理方法。 控制单元在显示单元上显示用于设置与打印相关的功能和选择纸张处理方法的设置画面,当选择纸张处理方法时,从存储单元获取与所选择的纸张处理方法相对应的功能限制指令内容, 基于所获取的功能限制指令内容,显示在显示单元上禁用了预定功能的设置和使用的设置屏幕,并且在设置屏幕上接收打印设置。 图像形成单元由控制单元基于在设置屏幕上接收的设置来控制,并在纸张上形成图像。

    • An image forming apparatus includes a power-state switching unit, a proxy-process executing unit, a proxy-generation-information transmission unit, and a printing-process take-over unit. The power-state switching unit switches among a plurality of power states including an ordinary state and a power-saving state. The proxy-process executing unit executes a proxy process, which is a proxy process to halfway through a printing process, to be executed by an external target unit. The proxy-generation-information transmission unit transmits proxy generation information to the target unit when the power of the target unit is in the ordinary state. The printing-process take-over unit takes over printing from halfway based on the received proxy generation information.
