A film carrier which, with a simple structure, can accurately check whether a reading head and a recording head are operating appropriately. Data for checking is determined in advance, and when a negative film begins to be withdrawn, direct current voltage is applied to the recording head. A leading end of the negative film is detected. Thereafter, the negative film is conveyed a fixed amount, the recording head records the data for checking, and the reading head reads recorded data. Next, read data and the data for checking are compared. When the read data and the data for checking do not match, it is determined that there is an abnormality in the recording head or the reading head, and error processing is carried out.

Method of checking magnetic heads, and film carrier

A printer control film and a film carrier allow proper management of the printer control film. When a Bull's-eye serving as the printer control film is inserted into the film carrier, magnetic information recorded on the Bull's-eye is read out. When it is judged based on the read out information that the Bull's-eye is an unused one, a start time of use is recorded on the Bull's-eye together with an apparatus ID. When it is judged that the Bull's-eye was used before, the apparatus ID, the used period, the number of times of use, and the like are read out from the Bull's-eye. When it is judged based on these data that the Bull's-eye carries proper images necessary for a conditioning operation, the number of times of use is updated. Subsequently, images recorded on the Bull's-eye are printed onto a printing paper.

Printer control film, film carrier, and method for managing a printer

In a printer processor, magnetic information is read out from a negative film by a magnetic head unit while the negative film is transported on a negative film carrier. Further, the density of each image is measured by an optical sensor of a sensor unit so as to detect a blank frame and an improperly exposed frame, thereby selecting images to be printed. After determining the print size of the selected images, a last image to be printed last, and a second last image to be printed before the last image is printed are specified. Based on the print sizes of the last image and the second last image, the printing order is determined before printing is performed.
