Abstract: An image processing apparatus includes a print mode initializing unit, a print mode modifying unit, a data retaining unit that retains the modified print settings for a predetermined period, a data receiving unit that receives data, a storage unit that stores the data, a data size calculating unit that calculates a size of an available storage area of the storage unit and a size of print data in accordance with the modified print settings when the data receiving unit receives the data when the modified print settings are retained. A comparing unit outputs a signal in response to a condition where the size of print data exceeds the available storage area. A print mode adjustor modifies, in response to the signal, the print settings so that the print data can be stored in the available storage area.

Abstract: A multi function device includes a main board configured to control functions corresponding to a model of the multi function device and a sub board configured to be connected with the main board. The sub board carries out peripheral control corresponding to the model of the multi function device. Main board first identification information indicative of a category of the main board is obtained, and main board second identification information intrinsic to each model of the multi function device is also obtained. Then, the model of the multi function device is identified based on the main board first identification information and the main board second identification information when the multi function device is powered on. Further, function information corresponding to the identified model is obtained. The main board and the sub board of the multi function device are controlled based on the function information so as to function correctly.

Abstract: A facsimile machine includes: a display that displays a menu screen including a menu item, an operation unit that allows a user an entry based on the menu screen, and a display control unit that changes the menu screen to be displayed on the display in response to the entry. The display control unit controls display/undisplay of the menu item based on a predetermined operational status of the facsimile machine when the display control unit changes the menu screen. The menu item corresponds to an operation effective to the predetermined operational status.

Abstract: A communication device, such as multifunction peripheral, includes a communication section communicable with an external device such as a call center, a mode changing section, a communication status indicating section, and a mode change enabling section. The mode changing section changes an operation mode from a first mode to a second mode. Settings of the communication device falling in a prescribed category are not changeable in the first mode but changeable in the second mode through user's operations. The communication status indicating section indicates that communications between the communication section and the external device are established. The mode change enabling section enables the mode changing section to change the operation mode from the first mode to the second mode under a condition where the communication status indicating section indicates that communications between the communication section and the external device are established.

Abstract: An ink jet recorder includes an ink jet head having nozzles, through which ink can be ejected. The recorder also includes an apparatus for purging the head. The apparatus includes a cap for covering the nozzles. The apparatus also includes a suction pump for sucking ink from the head through the cap covering the nozzles. The apparatus further includes a memory, a temperature sensor and a controller. The memory stores the purge interval at which the pump should suck ink. The sensor measures ambient temperature. If the measured temperature is abnormal, the controller replaces the stored purge interval with shorter interval. In this case, the apparatus purges the head at the shorter interval. This keeps the ejection of ink in good condition regardless of ambient temperature.
