  Hereinafter, an embodiment of an image forming apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram illustrating a schematic configuration of an ink jet printer as an example of an image forming apparatus according to the present exemplary embodiment.

  In the inkjet printer 100 shown in FIG. 1, the power supply unit 101 functions by a predetermined operation of the user, and from the voltage generation unit 102, the CPU 103, ROM 104, RAM 105, mechanical drive unit 106, operation panel 107, sensor unit 108, Power supply to the communication control unit 109, the EEPROM 110, and the timer 111 is started.

  The voltage generation unit 102 generates a voltage defined by the electronic devices such as the CPU 103, the ROM 104, the RAM 105, the mechanical drive unit 106, the operation panel 107, the sensor unit 108, the communication control unit 109, the EEPROM 110, and the timer 111.

  The CPU 103 controls the mechanical drive unit 106, the operation panel 107, the sensor unit 108, the communication control unit 109, and the EEPROM 110 according to the control program written in the ROM 104. For the EEPROM 110, the user's usage status data and model-specific information are read and rewritten.

  In addition to the control program described above, the ROM 104 presents component information (life / power), determination conditions (prescribed time, prescribed power) when information is presented by information provision processing, and information provision processing described later. Presentation information (a plurality of presentation information is prepared corresponding to various cases) is written by the manufacturer. Also, information on the usage status of the user (printing rate, usage time in each mode of each part, etc.) is sequentially written in the EEPROM 110 in accordance with the use of the image forming apparatus by the user. The usage status information written in the EEPROM 110 includes which parts or units (in this specification, “parts” and “units” are not distinguished from each other as components) and which operations under which printing rate and environmental temperature. It consists of data such as how many hours it has been used in the mode / operation state, that is, under which use conditions.

  On the other hand, the component information written in the ROM 104 is information as shown in Tables 1 to 10 shown in FIGS.

  Tables 1 to 4 shown in FIG. 7 show examples of component life information stored in the ROM 104, and in the operation mode specified by the manufacturer, are composed of data on the estimated amount of component life at the specified reliability. The example shows a data example of the estimated amount of product life at a reliability of 95%.

  Tables 1 to 4 target the units of the paper transport unit, the paper printing unit, and the power supply unit 101, which will be described later, and the estimated life (time) as a characteristic value, and the print quality high speed, print quality standard, and printing as factors. Each mode / state of quality clean, standby, energy saving, power off, temperature (Table 1 is 10 ° C, Table 2 is 20 ° C, Table 3 is 30 ° C, Table 4 is 40 ° C) (Tables 1 to 4 show the case where the printing rate CMYK is 10%, for example). The estimated amount of product life (estimated life) described here represents an estimated value of MTTF (average value of operation time until failure) of a product used in reliability engineering or the like. The estimated life calculation method can be calculated by the manufacturer performing continuous use under specific factor conditions (eg, temperature 20 ° C. high speed printing) and measuring the time until failure.

  By evaluating the above method for each factor condition, the estimated life for each factor condition can be obtained. However, since the evaluation becomes enormous when the above method is implemented, the “uneven usage method (for example, the usage rate of high-speed printing at a temperature of about 20 ° C. is the entire usage rate) stored in the EEPROM 110 of a similar model that has returned from the market. The estimated life can also be calculated by a method of associating the failure time with the data of the user who used 90% or more of the usage method). The object of the data example is a unit here, but may be a part. Regarding parameters, other parameters related to life may be added.

  Tables 5 to 8 shown in FIG. 8 are data (stress values) obtained by processing each of Tables 1 to 4, and are data obtained by dividing the product life specified by the manufacturer by the estimated life shown in Tables 1 to 4. Is defined as a stress value. Tables 5 to 8 calculated the product life specified by the manufacturer as 24 hours × 365 days × 5 years = 43800 hours. Using this stress value, the remaining life of each component or unit can be determined as remaining life = product life−Σ [stress value according to use conditions × use time]. Parts information such as Table 1 to Table 4 or Table 5 to Table 8 relating to the estimated amount of product life with the specified reliability is written in the ROM 104.

  Table 9 shown in FIG. 9 is a data example of the estimated amount of power consumption at the specified reliability in the operation mode specified by the manufacturer, and the power (watt) as the characteristic value, the print quality high speed, and the print quality as factors. For each mode / state of standard, print quality clean, standby, energy saving, and power OFF, for each temperature (10 ° C, 20 ° C, 30 ° C, 40 ° C in the example of Table 9), a predetermined printing rate (Table 9). Is data in which an estimated amount of power consumption is set at a printing rate of CMYK of 10%. This data is also written in the ROM 104 as the component information.

  Table 10 is an example of data obtained by multiplying the data in Table 9 by a power charge per 1 Wh (the example in Table 4 is calculated as 17 yen per 1 kWh). This data may also be stored in advance in the ROM 104 as component information.

  The operation panel 107 displays information by a display unit using an LCD (Liquid Crystal Display) or the like, and accepts a user operation input by an input unit using a touch panel. A communication control unit 109 performs communication control when receiving a remote operation by a user from an information processing apparatus such as an external PC connected via an electric communication line such as a LAN (Local Area Network). In accordance with an instruction transmitted from the user using the operation panel 107 or the communication control unit 109, an operation linked with information from the sensor unit 108 is performed, or a sheet is conveyed using a sheet conveying unit (described later) of the mechanical drive unit 106. Or paper printing is performed using a paper printing unit (described later) of the mechanical drive unit 106. The sensor unit 108 includes various sensors such as a temperature sensor and a sheet position detection sensor.

  The RAM 105 functions as a main memory of the CPU 103, and also has a function of increasing the processing speed as a cache memory in image data processing or the like. The timer 111 is a device having a time measuring function, and measures the usage time.

  Next, the paper transport unit provided in the mechanical drive unit 106 will be described with reference to FIG. FIG. 2 is a diagram illustrating a schematic configuration of the paper transport unit included in the mechanical drive unit 106. The paper transport unit shown in the figure is the same as the paper transport means provided in a general ink jet printer.

  The paper transport unit 200 includes a paper transport DC motor 201 as a drive source. The power from the paper transport DC motor 201 is transmitted to the gear 202, the paper transport shaft 204 fixed to the gear 202 and the transport rollers 205a to 205e fixed to the paper transport shaft 204 rotate, and the paper 220 is transported to the paper. It is transported at an arbitrary speed in the direction 1/230 or the sheet transport direction 2/240. At that time, the position of the sheet 220 is detected by the sheet conveyance encoder sheet 203 and the transmission type sensor 206. The paper transport bearings 210 and 211 are provided to rotate the transport rollers 205a to 205e at arbitrary positions.

  Next, the paper printing unit provided in the mechanical drive unit 106 will be described with reference to FIG. FIG. 3 is a diagram illustrating a schematic configuration of a paper printing unit provided in the mechanical driving unit 106. The paper printing unit shown in the figure is the same as the paper printing means provided in a general ink jet printer.

  The paper printing unit 300 includes a paper printing DC motor 301 as a drive source. The power from the paper printing DC motor 301 is transmitted to the timing belt 303, the paper printing encoder sheet 304 and a transmission type sensor (not shown) detect the position of the paper 320, and the paper printing mechanism 305 fixed to the timing belt 303 Move and eject liquid of any color at any position. Positioning in the height direction is performed by the paper printing mechanism shaft 306 and the paper printing mechanism bearings 307 and 308. Depending on the printing method, for example, images such as a black print portion 330, a black 50% print portion 331, a black 25% print portion 332, and a non-printed background portion 333 shown in FIG.

  When a user performs printing using an image forming apparatus such as an ink jet printer having the above-described configuration, the user sends a print job to the image forming apparatus from an application on an information processing apparatus such as a PC. The image forming apparatus acquires print data from a print job, and has three print modes (print speed priority mode, normal print mode, and image quality priority mode defined by the manufacturer). Execute), execute printing in the determined printing mode, and output the printed matter.

  By the way, if one component fails in the image forming apparatus, there is a tendency that the function of the entire system is impaired, and the following problems arise in the normal use method in the image forming apparatus as described above.

  For example, when the user uses only the print speed priority mode, the stress is concentrated on the paper transport unit 200, so that the paper transport unit 200 breaks down early, and the life of the paper transport unit 200 is the life of the entire system. It becomes.

  Further, when only the image quality priority mode is used, stress concentrates on the paper printing unit 300, so that the paper printing unit 300 breaks down early, and the life of the paper printing unit 300 becomes the life of the entire system.

  Also, if only the normal printing mode can be used to extend the service life, it will take time when you want to rush to print, and the image quality will deteriorate when you want to print with high definition, which will limit the user. .

  In the image forming apparatus of the present embodiment, the product can be used comfortably for a long period of time (information providing process 1) and the power consumption can be suppressed (information providing) by controlling as follows. Process 2).

  Next, a control flow at the time of printing in the image forming apparatus, which is characteristic in the present embodiment, will be described with reference to FIG. FIG. 4 is a flowchart showing a control flow at the time of printing in the image forming apparatus of the present embodiment.

  When printing is performed, first, print data to be printed is selected from the accumulated print data (step S401).

  Next, a component information grasp determination is performed (step S402). Here, it is determined whether or not the user has selected a mode for performing component grasping. The selection by the user can be performed by a predetermined operation using the operation panel 107, for example.

  If it is in the mode for grasping the component information (Yes in step S402), the information providing process (details will be described later) to the user in step S403 is executed, and then the process proceeds to step S404. (No in step S402), the process proceeds to step S404.

  In step S404, the print mode specified in the print job is determined. If the print speed priority mode is set, the process proceeds to step S405, and printing is executed with priority on the print speed. On the other hand, in the normal printing mode, the process proceeds to step S406, and normal printing is executed. On the other hand, in the image quality priority mode, the process proceeds to step S407, and printing is performed with image quality priority.

  Printing is completed by the series of processes described above.

  Next, details of the information providing process in step S403 will be described. First, the information providing process 1 will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart illustrating an example of the information providing process in step S403.

  First, the difference in remaining life between components is calculated (step S501).

  Next, it is determined whether or not the difference in remaining life between components is equal to or longer than a specified time (step S502).

  If the difference in the remaining life between the parts is less than the specified time based on the above determination (No in step S502), the process proceeds to step S503 to indicate to the user that the use method is good for the life of each part. To do.

  On the other hand, if it is determined in the above determination that the remaining life difference between the parts is equal to or longer than the specified time (Yes in step S502), the process proceeds to step S504 to present the user with a condition that the difference in remaining life between the parts is less than the specified time. To do.

  In the above processing, the part information is compared with the usage status of the user, and the following method is implemented as a method for suggesting to the user a method for prolonging the estimated product life.

  For example, when a user performs high-speed printing for 5000 hours at a printing rate of 10% and a temperature of 40 ° C., and performs high-quality mode clean printing for 3000 hours at a printing rate of 10% and a temperature of 40 ° C., the user's The remaining life of each component or unit can be calculated using the EEPROM 110 in which the usage status is stored and the ROM 104 in which the stress value is stored (here, the stress value is stored in the ROM 104 as component information). it can. The remaining life calculation results for each component or unit under the above conditions are described below.

  Paper transport unit: 43800- [0.63 (stress value) × 5000 hours + 0.49 (stress value) × 3000 hours] = 39180 hours

  Paper printing section: 43800- [0.58 (stress value) × 5000 hours + 0.80 (stress value) × 3000 hours] = 38500 hours

  Power supply unit: 43800− [0.88 (stress value) × 5000 hours + 0.88 (stress value) × 3000 hours] = 36760 hours

  In the above example, the remaining life of the power supply unit 101 is the shortest, and the difference in remaining life (2420 hours) between the power supply unit 101 and the paper transport unit 200 is equal to or longer than a specified time (for example, 1000 hours). As a method of reducing the stress, a condition for reducing the stress of the power supply unit 101 is presented to the user. As a method of presentation, the user interface (the operation panel 107 or a PC used by the user by remote control) can be used with the "probability of extending the service life when the operating environment temperature is lowered" or "standard printing is possible. Providing “etc., etc. increases the probability that the life will be extended as long as it is used”, so that the remaining life between each unit or part becomes average, and the life of the image forming apparatus can be extended. The information presented here is stored as presentation information in the ROM 104 as described above, and necessary presentation is performed with reference to this information.

  Next, details of another example of the information providing process in step S403 will be described. Here, the information providing process 2 will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart illustrating another example of the information providing process in step S403.

  First, a difference in power consumption between usage methods is calculated (step S601).

  Next, it is determined whether or not the power consumption difference calculated above is greater than or equal to the specified power (step S602).

  If the difference in power consumption is less than the specified power in the above determination (No in step S602), the process proceeds to step S603 to indicate to the user that the user is using a good method for power consumption.

  On the other hand, if the difference in power consumption is greater than or equal to the specified power in the above determination (Yes in step S602), the process proceeds to step S604 to present the user with a condition that the power consumption is less than or equal to the specified power.

  9 is stored in the ROM 104 as the component information when the user is using the specified power consumption (for example, specified power of 27 W) or more under the condition that the user grasps the component information. If the user is using an environment temperature of 40 ° C and printing quality high speed (the estimated amount of power consumption is 29 W at this time), “If the printing quality is standard, 2 W can be saved.”, “ 4W can be saved if the print quality is clean. "Is presented to the user via the user interface. If the user modifies the usage method according to this presentation, the power consumption of the image forming apparatus can be suppressed. Note that the information presented here is also stored as presentation information in the ROM 104 as described above, and necessary presentation is performed with reference to this information.

  Further, when the user inputs a charge corresponding to the amount of electric power, for example, 17 yen per kWh, into the image forming apparatus (the data shown in Table 10 in FIG. Calculating the cumulative power consumption fee, presenting this fee to the user, and presenting the power consumption reduction method, the user is more aware of the power consumption reduction, and more power consumption It can also be reduced.

  The control flow in the image forming apparatus according to the present embodiment has been described above. The difference between the control flow and the conventional one is that the part information grasping determination is performed between the print data selection (S401) and the printing mode determination (S404). (S402) and information provision processing (S403) to the user are added. When the user selects whether or not to grasp the component information and grasps the component, the information provision of the method for extending the life is performed according to the flowchart illustrated in FIG. The user can also select a mode that does not require the component information grasp determination (S402).

  Whether to use information effectively is left to the user and is not a process that restricts the user. If the user carries out the information as provided, the stress applied to each component can be dispersed and the life can be extended.

  In addition, according to the flowchart illustrated in FIG. 6, information on a usage method for suppressing power consumption is provided, and if the user performs as provided, the power consumption can be reduced. Note that the process shown in FIG. 5 and the process shown in FIG. 6 may be performed only in one direction, or may be performed in parallel.

However, the image forming apparatus is not limited to the image forming apparatus main body, and the entire image forming system including other apparatuses connected to the image forming apparatus by wire or wirelessly. By applying the control, the failure rate of the entire system can be reduced and the life can be extended, and the power consumption can be reduced.
