摘要： Certain examples described herein relate to splice detection. In certain cases, a splice is detected in a web being conveyed towards a transfer member of the printing system. In certain cases, a print frame is identified from a sequence of pending print frames using successive repeat lengths of the sequence and a distance of the splice from the transfer member. The identified print frame is to be transferred from the transfer member across the splice. In certain cases, writing of the identified print frame onto a photo-imaging plate of the printing system is deferred. In certain examples, the web is disengaged from the transfer member following transfer of an image of a print frame preceding the identified print frame. The web is re-engaged with the transfer member so as to transfer an image of the identified print frame to the web from the transfer member after the splice is conveyed beyond the transfer member.

摘要： In one example of the disclosure, it is determined that an amount of print agent remaining in a print agent container of a print apparatus is below a threshold level. An amount of print solution is transferred from a print solution reservoir of the print apparatus, or an amount of print solution solvent is transferred from a solvent reservoir of the print apparatus, into the print agent container. At least some of the remaining print agent is caused to dissolve into the amount of print solution or print solution solvent to forma rinse solution. The rinse solution is transferred from the print agent reservoir to the print solution reservoir.

摘要： In an example, a method for controlling termination of a print procedure subsequent to a node reset within print apparatus including a plurality of nodes includes identifying the node at which the reset occurred, and controlling operation within the print apparatus by way of a selected node. The selected node is different from the identified node and selected responsive to the identification of the identified node for operation of a component of the print apparatus as part of a termination procedure.

摘要： According to examples, a method comprises receiving, at a processor, print job data relating to a print job to be performed by a print apparatus, the print job data defining order in which a plurality of colour separation images are to be transferred onto an imaging surface of the print apparatus. The method may comprise determining, based on the print job data, a number of null segments to be inserted into the print job and a location at which each null segment is to be inserted amongst the plurality of colour separation images. A print apparatus and a machine-readable machine are also disclosed.

摘要： An apparatus is provided for controlling a liquid electrophotography printer (LEP). The LEP may include a plurality of ink developers, IDs, to transfer charged ink to a photoreceptor, by virtue of a potential difference between the engaged ID and the photoreceptor selectively dischargeable to allow an image to be formed on a print medium in use through printing a spread of plural colour separations thereon each corresponding to ink from one of a plurality of engaged IDs. the apparatus may comprise a print controller to, in use monitor an order of colour separations to be printed onto the print medium. The print controller may also detect in the order of colour separations an empty separation of an ID followed by a printing separation of the same ID, an empty separation representing a separation in which no image is formed on the photoreceptor and the engaged ID is at a voltage different to the voltage of the ID for a printing separation so as to, in the empty separation, substantially wet the photoreceptor and substantially not transfer ink thereto. The print controller may also, in response to the detection, replace in the order of the colour separations the ID for the empty separation with a different ID.
摘要翻译：提供了一种用于控制液体电子照相印片机（LEP）的装置。 LEP可以包括多个油墨显影剂ID以借助于被接合的ID和可选择性地可放电的感光器之间的电位差将带电的油墨转印到感光器，以允许通过印刷在使用中的印刷介质上形成图像其上分别对应于来自多个接合ID之一的墨水的多个分色的分布。该设备可以包括打印控制器，以在使用中监视要打印到打印介质上的分色顺序。打印控制器也可以按照分色次序检测ID的空白分离，接着是相同ID的打印分离，空白分离表示在感光器上没有图像形成的分离，并且所接合的ID处于电压不同于用于印刷分离的ID的电压，以便在空分离时，基本上润湿感光体并且基本上不将油墨转印到其上。为了响应检测，打印控制器还可以按照分色顺序替换具有不同ID的空分离的ID。
