[0009] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the claimed invention. Although multiple features are described in the embodiments, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined arbitrarily. Furthermore, in the accompanying drawings, the same reference numerals are used to designate the same or similar components, and redundant explanations will be omitted.

[0010] (Overall configuration of the recording device) Fig. 1 is a perspective view showing the appearance of a recording device 101 according to an embodiment. Fig. 2 is a perspective view showing a part of the internal structure of the recording device 101. To facilitate understanding of the structure, the figure shows an X direction corresponding to the left-right or width direction of the device, a Y direction corresponding to the front-rear or depth direction of the device, and a Z direction corresponding to the up-down or height direction of the device. The X, Y, and Z directions are assumed to intersect (substantially perpendicular to) each other.

[0011] The recording device 101 is an inkjet printer that performs recording using an inkjet method, and performs recording by ejecting ink onto a sheet-like recording medium 205 such as paper to form an image. The concept of an image includes characters, symbols, numbers, images, photographs, etc., as well as the blank spaces formed around them. The recording device 101 may be a multifunction peripheral (MFP) that has a recording function as its main function and also has other auxiliary functions such as a scanner function, a copy function, and a facsimile function.

[0012] In this embodiment, the printing apparatus 101 includes a carriage 201, a carriage bearing 202, a guide rail 203, an encoder sensor 204, a print head 206, an ink tank 207, and a linear scale 208 (see FIG. 2).

[0013] The print head 206 has an array of multiple nozzles (ink ejection ports) (not shown), and performs printing by individually ejecting ink supplied from an ink tank 207 from each nozzle. The carriage 201 is slidably supported on a guide rail 203 extending in the X direction, and is capable of reciprocating in the X direction along the guide rail 203. The print head 206 is mounted on this carriage 201, which enables it to scan in the X direction, and it can perform printing on a print medium 205 during this scan.

[0014] The linear scale 208 is provided along a belt for reciprocating the carriage 201, and the encoder sensor 204 detects the linear scale 208. The position of the carriage 201 or the recording head 206 can be identified based on the detection result of the encoder sensor 204. Although details will be described later, it is also possible to determine the total movement distance of the carriage 201 based on the detection result of the encoder sensor 204. While the carriage 201 is moving, the movement distance of the carriage 201 is cumulatively measured, and the measurement result is stored in a predetermined memory (for example, memory 308 described below) as the total movement distance, and is updated when the carriage 201 moves further.

[0015] The carriage bearing 202 is a bearing provided on the guide rail 203, and allows the carriage 201 to slide easily. Details will be described later, but in this embodiment, the carriage bearing 202 is shown as an example of a part (replacement part) that needs to be replaced due to deterioration (wear, etc.) caused by cumulative use.

[0016] In this example, a roll sheet formed by winding a long sheet is shown as the recording medium 205, but the recording medium 205 may also be a cut sheet of a predetermined size.

[0017] 3 is a block diagram showing an example of the system configuration of the recording device 101. The recording device 101 further includes an operation panel 102, a recording control unit 301, a carriage motor 307, and a transport motor 309 (see FIGS. 1 and 3). The recording control unit 301 includes a CPU 302, a power supply unit 303, an interface unit (IF unit) 304, motor drivers 305 and 306, and a memory 308.

[0018] The operation panel 102 is configured to be able to accept user operation input and to be able to display information necessary for recording. A touch panel display is typically used for the operation panel 102, but the function of accepting operation input and the function of displaying necessary information may be provided separately.

[0019] In this example, the memory 308 is shown as a storage device in a broad sense, and is a concept that includes non-volatile memory such as a solid state drive (SSD) and volatile memory such as a random access memory (RAM).

[0020] A CPU (Central Processing Unit) 302 reads out a program for realizing the recording function and develops it on RAM, while performing arithmetic processing for realizing the recording function, thereby realizing each function exemplified in this embodiment.

[0021] As one example, CPU 302 executes a print job received from an external device via interface unit 304. For example, CPU 302 processes image data included in the print job to generate print data and temporarily stores the data in RAM. As another example, CPU 302 can read image data from an external memory via interface unit 304 based on an operation input to operation panel 102, and generate the print data. CPU 302 controls the driving of motor drivers 305 and 306 and print head 206 based on the print data obtained in this manner.

[0022] A motor driver 305 drives a transport motor 309, which generates power to transport the recording medium 205 along the transport path. A motor driver 306 drives a carriage motor 307, which generates power to move the carriage 201 back and forth.

[0023] The power supply unit 303 generates voltages corresponding to the above-mentioned individual elements based on an external voltage, and supplies the corresponding voltages to the elements, thereby causing the individual elements to operate appropriately.

[0024] With this configuration, intermittent conveyance, in which the recording medium 205 is conveyed a predetermined amount and then the conveyance is suppressed, and scanning recording, in which the recording head 206 is scanned during the suppression of conveyance, are repeated, thereby achieving the desired recording on the recording medium 205. Such a print head 206 is also referred to as a serial head. In this embodiment, printing is performed by the carriage 201 scanning the print head 206, so the print head 206 and carriage 201 may be collectively referred to as a printing unit.

[0025] (Replacement parts for recording devices) In such a recording apparatus 101, parts may need to be replaced due to deterioration caused by cumulative use of the drive mechanism. In this embodiment, as an example of a replaceable part, the carriage bearing 202 provided on the guide rail 203 is recommended for replacement when it no longer meets a predetermined standard. For example, if the carriage bearing 202 deteriorates, friction increases when the carriage 201 moves, making it difficult to properly scan the recording head 206. On the other hand, the degree of deterioration of replacement parts may vary depending on external environments such as humidity and temperature, and product variations, which may also change the friction. Therefore, it is generally relatively difficult to determine whether parts need to be replaced, and a technology that can more appropriately determine whether parts need to be replaced with a relatively simple configuration is required.

[0026] 5 is a flowchart showing a part of the determination of whether or not a part needs to be replaced (determination of whether or not a part needs to be replaced) according to this embodiment. This flowchart is mainly executed by the CPU 302, and the outline thereof is to detect the driving load of the carriage motor 307 during the cleaning process of the print head 206.

[0027] In step S201 (hereinafter simply referred to as "S201," and the same applies to other steps described below), it is determined whether or not a cleaning process (head cleaning process) for the print head 206 needs to be performed. The head cleaning process is performed, for example, when the printing device 101 is started up, when the printing device 101 has been continuously operated for a predetermined period of time, or when the print head 206 has printed more than a predetermined amount of data. In the head cleaning process, the function of the print head 206 is restored by suctioning waste ink using a recovery unit (not shown). The recovery unit is disposed at an end of the movable area of ​​the carriage 201. The carriage 201 carrying the print head 206 is moved across substantially the entire movable area of ​​the carriage 201, that is, from one end to the other end of the movable area, before or after the suction operation by the recovery unit. If it is determined that the head cleaning process needs to be performed, the process proceeds to S202; otherwise, the process ends.

[0028] In S202, detection of the drive load of the carriage motor 307 begins. As an example, the carriage motor 307 is driven by PWM (Pulse Width Modulation) control, and in this case, the drive load is detected based on the duty ratio of a PWM signal used to control the drive of the carriage motor 307. As another example, the detection may be performed based on the power consumption of the carriage motor 307.

[0029] In S203, a forward scanning operation is started in which the carriage 201 is moved from one end of the movable area to the other end to scan the print head 206. Upon completion of the forward scanning operation, the process proceeds to S204.

[0030] In S204, the carriage 201 is moved from the other end side to one end side of the movable area, and a backward scanning operation is started to scan the print head 206. Upon completion of the backward scanning operation, the process proceeds to S205.

[0031] The forward scanning operation in S203 and the backward scanning operation in S204 are performed at the same and constant scanning speed. During these operations, ink ejection from the print head 206 is suppressed, but ink ejection may be performed if necessary.

[0032] In S205, the print head 206 is stopped at a predetermined position, and detection of the driving load of the carriage motor 307 is completed. In this manner, the driving load of the carriage motor 307 while the carriage 201 moves over substantially the entire movable range is detected. The driving load of the carriage motor 307 may be detected for any part of the movable range as long as the carriage 201 is moving within the movable range. As an example, the driving load may be detected only for the central portion of the movable range where the moving speed of the carriage 201 is likely to stabilize.

[0033] In S206, a predetermined calculation process is performed based on the detection results (the driving load of the carriage motor 307 during the forward scanning operation and the backward scanning operation). Here, a duty ratio of the PWM signal that can achieve the desired speed of scanning of the print head 206 (movement of the carriage 201) is calculated. The desired speed here refers to the scanning speed that the print head 206 should have when scanning and printing with the print head 206. Therefore, if the driving load of the carriage motor 307 is large when the print head 206 achieves this scanning speed, the duty ratio of the PWM signal is calculated to be a large value.

[0034] In S207, the calculated duty ratio of the PWM signal is saved in the RAM as one of the parameters to be used in subsequent recordings and updated.

[0035] In S208, the head cleaning process is completed with the recovery of the function of the print head 206, and this flowchart ends. Note that the head cleaning process may be completed within this flowchart. Therefore, the waste ink suction operation by the recovery unit may be performed at an appropriate timing between S202 and S208 (for example, before S203, after S204, or after S203 and before S204).

[0036] 6 is a flowchart for determining whether or not a part needs to be replaced according to this embodiment. This flowchart is mainly executed by the CPU 302, and the gist of it is that the display regarding part replacement is switched based on the total movement distance of the carriage 201 and the duty ratio of the PWM signal.

[0037] In S301, it is determined whether or not a predetermined condition is met. This step can be said to be a step for determining whether or not to start the present flowchart. Here, for example, if the recording device 101 is started up, if the recording device 101 returns from sleep mode, or if a print job is completed, the predetermined condition is deemed to be met and the process proceeds to S302; otherwise, the process returns to S301. In other words, the steps from S302 onward may be performed before the next recording operation is executed.

[0038] In S302, it is determined whether the total movement distance Lcr of the carriage 201 is greater than a predetermined reference value Lcr1. Here, as described above, the movement distance of the carriage 201 is cumulatively measured based on the detection results of the encoder sensor 204, and is stored as the total movement distance Lcr in, for example, the memory 308. It is then updated when the carriage 201 moves further. If Lcr>Lcr1, the process proceeds to S303, otherwise the process proceeds to S311.

[0039] In S303, it is determined whether or not the PWM duty ratio Rdt, which indicates the duty ratio of the PWM signal updated in S207, is greater than a predetermined reference value Rdt1. If Rdt>Rdt1, the process proceeds to S304, otherwise the process proceeds to S311.

[0040] In S304, it is determined whether the total movement distance Lcr of the carriage 201 is greater than a predetermined reference value Lcr2 (where Lcr2>Lcr1). If Lcr>Lcr2, the process proceeds to S305, otherwise the process proceeds to S310.

[0041] In S305, it is determined whether the PWM duty ratio Rdt is greater than a predetermined reference value Rdt2 (where Rdt2>Rdt1). If Rdt>Rdt2, proceed to S306; otherwise, proceed to S310.

[0042] In S306, it is determined whether the PWM duty ratio Rdt is greater than a predetermined reference value RdtE (where RdtE>Rdt2 (>Rdt1)). If Rdt>RdtE, proceed to S307; otherwise, proceed to S309.

[0043] In S307, a signal (hereinafter, an error signal) is output to the operation panel 102 to display that the recording operation cannot be performed, and this flowchart ends.

[0044] In S309, a signal (hereinafter, W2 signal) for displaying on the operation panel 102 that a part replacement should be performed is output, and this flowchart ends.

[0045] In S310, a signal (hereinafter, W1 signal) is output to cause the operation panel 102 to display that the time to replace the part is within the reference period, and this flowchart ends.

[0046] In S311, a signal (hereinafter, OK signal) is output to the operation panel 102 to display that the recording operation can be performed, and this flowchart ends.

[0047] (Display content related to replacement parts) FIG. 4 is a diagram for explaining the display content related to component replacement based on the flowchart of FIG. 6. The horizontal axis in the figure corresponds to the total moving distance Lcr indicating the cumulative measurement result of the moving distance of the carriage 201, and its unit is [m (meter)]. The vertical axis in the figure corresponds to the PWM duty ratio Rdt indicating the duty ratio of the PWM signal updated at S207, and its unit is [% (percent)].

[0048] The display related to component replacement is output to the operation panel 102, and its content is switched based on the comparison of the above Lcr and Rdt with the reference values Lcr1, Lcr2, Rdt1, Rdt2, and RdtE.

[0049] In the example of FIG. 4, when Rdt > RdtE, regardless of Lcr, it becomes "error display" and is displayed based on the error signal output at S307. Also, when Rdt2 < Rdt ≤ RdtE and Lcr2 < Lcr, it becomes "W2 display" and is displayed based on the W2 signal output at S309. Also, when Rdt > Rdt1 and Lcr > Lcr1, and when Rdt2 < Rdt ≤ RdtE and Lcr2 < Lcr does not hold, it becomes "W1 display" and is displayed based on the W1 signal output at S310. In other cases, it becomes "OK display" and is displayed based on the OK signal output at S311.

[0050] Here, the "OK display" indicates that the recording operation is executable, and it may be a blank display (no display) instead of the "OK display". Also, the "W1 display" is the first warning display indicating that it is time to replace the component (in this example, the carriage bearing 202) within the reference period, and as an example, character information such as "The replacement time of the component is approaching." is displayed. Also, the "W2 display" is the second warning display indicating that the above component should be replaced, and as an example, character information such as "Please replace the component." is displayed. In addition, the "error display" is a third warning display indicating that the recording operation cannot be performed, and as an example, text information such as "The recording function is limited. Please contact the customer service center" is displayed.

[0051] The parameters may be set based on an evaluation test for evaluating the degree of deterioration of the replacement part, for example. Lcr1=3.87×10 9 [m] First reference measurement value Lcr2=4.30×10 9 [m] Second reference measurement value Rdt1=95[%] First reference detection value Rdt2=97[%] Second reference detection value RdtE=100[%] Upper limit of tolerance can be set as follows.

[0052] In this embodiment, the above-mentioned "OK display", "W1 display", "W2 display", and "error display" are realized by the operation panel 102, but instead, they may be notified by a warning sound, voice guide, etc.

[0053] In summary, if the PWM duty ratio Rdt corresponding to the detection result obtained from the flowchart of FIG. 5 is a detected value outside the allowable range (if Rdt>RdtE), it is displayed that the recording operation of the recording device 101 cannot be performed. Furthermore, if the PWM duty ratio Rdt is a detected value greater than the first reference detected value (if Rdt>Rdt1), it is displayed that the time to replace the part is within the reference period. Furthermore, if the total movement distance Lcr, which is the cumulative measurement result of the movement distance of the carriage 201, is greater than the first reference measurement value (Lcr>Lcr1), it is displayed that the time to replace the part is within the reference period. On the other hand, if the PWM duty ratio Rdt is a detected value greater than the second reference detected value and the total movement distance Lcr is a measured value greater than the second reference measured value (if Rdt>Rdt2 and Lcr>Lcr2), a message is displayed indicating that the part should be replaced.

[0054] When a part is replaced, the total travel distance Lcr stored in the memory 308 can be initialized (Lcr=0), which causes the total travel distance Lcr to be measured again for the new replaced part.

[0055] In this embodiment, the carriage bearing 202 is shown as an example of a replacement part, but the replacement part is not limited to this example as long as it is a part that requires replacement due to deterioration caused by cumulative use. In this embodiment, the replacement part is at least a part of the mechanism for transmitting the power of the carriage motor 307 to the carriage 201. Therefore, in this embodiment, the part to be replaced may be only the carriage bearing 202, but the carriage 201 and / or the guide rail 203 may also be replaced incidentally.

[0056] As described above, according to this embodiment, the determination of whether or not part replacement is required is made based on both the cumulative measurement result of the movement distance of the carriage 201 (total movement distance Lcr) and the detection result of the drive load of the carriage motor 307 (PWM duty ratio Rdt). Generally, because the deterioration of replacement parts can vary depending on the external environment, it is relatively difficult to determine whether part replacement is necessary. In contrast, according to this embodiment, the PWM duty ratio Rdt is referenced in addition to the total travel distance Lcr. When the driving load of the carriage motor 307 is large, the PWM duty ratio Rdt becomes large regardless of the total travel distance Lcr. Therefore, according to this embodiment, it is possible to determine whether part replacement is necessary by taking into account the actual degree of deterioration of the replacement part. Therefore, according to this embodiment, unnecessary part replacement can be prevented, which is advantageous in improving the usability of the recording device 101.

[0057] (program) The present invention may be realized by supplying a program that realizes one or more functions of the above-described embodiments to a system or device via a network or a storage medium, and having one or more processors in a computer of the system or device read and execute the program. For example, the present invention may be realized by a circuit (e.g., an ASIC) that realizes one or more functions.

[0058] (others) In the embodiments, individual elements are named based on their main functions, but the functions described in the embodiments may be sub-functions and are not strictly limited to these expressions. Furthermore, these expressions can be replaced with other similar expressions. For the same purpose, the expression "unit" can be replaced with "tool," "component," "member," "structure," "assembly," etc. Alternatively, these terms may be omitted or added. In addition, the ink is not limited to a colored liquid containing a dye or pigment, but may be a colorless, transparent liquid, i.e., the ink is a liquid in a broad sense. From this perspective, the recording device 101 may be referred to as a liquid ejection device, and the recording head 206 may be referred to as a liquid ejection head.

[0059] Furthermore, two or more selectable elements exemplified in the embodiments are not strictly limited to the examples and may be arbitrarily combined, for example, each of the two or more selectable elements may be additionally or alternatively selected. For example, when two elements A and B are arbitrarily combined, they may be expressed as "A and / or B" or "at least one of A and B" to indicate either A only, B only, or both A and B.
