Today, office automation (OA) devices such as printers, scanners, and fax machines are widely used. Each office automation device is being developed at high performance to expand its unique capabilities, resulting in more expensive products. On the other hand, by developing each of the office automation equipment that was used independently as a single product has been produced to reduce the economic burden on the user. Such a device is generally called a multifunction device.

In general, since the all-in-one has an original scanning device, a printing device, and a communication device, these devices are used to scan originals, fax jobs to send and receive scanned original data, and print to print a host computer or received fax data. Perform work lights.

A general inkjet multifunction printer, as shown in FIG. 1, is a carrier driving unit (100) composed of a carrier motor (120) for moving a carrier mounted with an ink head (110), a driving driver and related devices thereof, and an automatic paper feeder. Alternatively, a line feed motor 200 including a line feed motor, a drive driver and related devices for picking up and transporting paper prepared in a manual feeder, and a document are transferred to the scanning module 310 through a scan motor to scan the paper. A scan driver 300 comprising a driver driver and related devices for driving the module 310 to scan an original, and a multifunction controller for controlling the operation of each driver and communicating with a host computer and facsimile data communication with another multifunction device. It consists of 400.

Such an inkjet MFP may have three or more driving units, and an operation profile for operating each driving unit may be due to the mechanical characteristics of the driving unit when a driving request is generated to the driving unit in a stationary state as shown in FIG. 2. Acceleration section to prepare the drive unit until the normal operation can be performed, constant speed section to the drive unit performs the normal operation, deceleration section to gradually reduce the drive speed due to the mechanical characteristics when the drive termination request occurs during the normal operation, After a certain time, the driving section is divided into a stop section.

In general, an inkjet all-in-one can send a fax while printing the print data sent from the host computer, and vice versa, it can receive and print the print data during a fax transmission. It is called a (dual job).

Referring to Fig. 3, the driving profile of each driving unit when performing a dual operation of sending a fax while printing the print data in the inkjet MFP will be described as follows: ① section is a section in which a carrier driver and a scan driver are simultaneously driven and ② section Is a section in which the line feed driver and the scan driver simultaneously drive, and in the section ⓐ, the carrier driver, the line feed driver, and the scan driver are operated simultaneously.

Ⓐ As in the section, when three driving units are operated at the same time, the power supplied from the power supply is overloaded, and a phenomenon such as power dip may occur, which may cause an error in the mechanical operation of the multifunction device. In order to supply more power than necessary, the power capacity must be increased, resulting in an increase in cost.

Therefore, the present invention has been made to solve the problem that the three driving unit is driven at the same time is generated by the power overload phenomenon to avoid the power overload phenomenon by avoiding the section in which the three driving unit at the same time overlapping operation. have.

Another object of the present invention is to solve the problems such as power drop derived from the generation of wave overload while using the power supply in use as efficiently as possible.
