Example systems and related methods may relate to monitoring performance of an image forming operation. Namely, a system may include an image forming apparatus configured to execute an operation. The system further includes an external sensor circuit comprising one or more sensors and a processor. The system yet further includes a host computing device configured to generate, in response to receiving notifications of a status of the operational parameter received from the one or more processors of the sensor circuit, a first timestamp indicative of when the image forming apparatus started to execute the printing operation, and a second timestamp indicative of when the image forming apparatus completed the printing operation. The host computing device is further configured to generate a log file. Data of the log file includes the first timestamp and the second timestamp, and is indicative of how quickly the image forming apparatus executed the operation.

An image forming apparatus includes a plurality of image forming units configured to form images, an image bearing member, a detection unit configured to detect a pattern image formed on the image bearing member, the pattern image being used for detecting a color misregistration, a controller configured to control the plurality of image forming units to form a plurality of first pattern images, each having a different color, and control the detection unit to detect the color misregistration, and a storage unit configured to store data on the color misregistration, wherein the controller corrects an image forming position based on the stored data, and wherein in a case where an error is detected in the data, the controller controls the plurality of image forming units to form a plurality of second pattern images, different form the plurality of first pattern images, before the plurality of first pattern images is formed.

Provided is an image forming system in which a plurality of image forming apparatuses are tandem-connected in series. The image forming system comprises a controller that processes image data used for image formation and controlling the image forming apparatus, wherein the controller has a function of outputting an inspection image for obtaining calibration data of the image forming apparatus by the image forming apparatus and enabling acquisition of the reading result read by an image reading unit, and in the function, the controller prepares data for the inspection image to be output by one image forming apparatus and duplicates the data, and transmits inspection image data to each image forming apparatus, and performs control so that image is formed on different transfer media respectively by the respective image forming apparatuses based on the inspection image data received by each image forming apparatus.

A first communication apparatus including a control device configured to: receive a specific signal from a second communication apparatus; determine whether an inter-device distance between the communication apparatuses is equal to or smaller than a first distance; cause a server to supply printing data to a printer when the inter-device distance is equal to or smaller than the first distance; again receive the specific signal from the second communication apparatus; determine whether the inter-device distance is equal to or smaller than a second distance that is smaller than the first distance by using a second reception radio wave intensity of the again-received specific signal; and cause the printing execution unit to execute printing in accordance with the printing data when it is determined that the inter-device distance is equal to or smaller than the second distance.

An image forming apparatus downloads a content via a network and prints an image of the content. when a shift instruction to shift to a first display process is input from a user operation unit after a registration process is completed, a control unit repeats the first display process, a second display process and the registration process so that another content information is newly created and stored in a first storage unit, and when a print instruction to start printing is input from the user operation unit after the registration process is completed, the control unit downloads contents indicated with the content information stored in the first storage unit wherein these contents are defined as print target contents, and sequentially executes print operations for the images of one or more of the print target contents with the print conditions associated with the print target contents.
