Description

  The present invention relates to a recording apparatus. More specifically, the present invention relates to a recording apparatus having a power saving mode for suppressing power consumption in addition to an operation mode in which ink is ejected toward a recording medium to execute a recording operation.

  In a recording apparatus such as an ink jet recording apparatus, it is rather rare that the recording operation continues to be performed continuously during a period in which the power is turned on, and there is a period of waiting without performing the recording operation. On the other hand, when the power switch is turned on to start up, a predetermined initialization operation is executed in the recording apparatus. In the initialization operation, in addition to initialization of the built-in electronic circuit, a mechanical initial stage such as a recording head moving mechanism that moves the recording head, a conveyance mechanism that conveys the recording medium, and a pressure mechanism that pressurizes the ejected ink, etc. Is also executed.

  Since these many kinds of initialization operations are executed, it takes a considerable time from when the user turns on the power switch until the recording apparatus starts the recording operation. For this reason, once the power switch of the recording apparatus is turned on, there are many users who do not shut off the power even if the standby time is somewhat longer.

  Therefore, as described in Patent Document 1 below, there is a recording apparatus capable of restarting an operation mode without an initialization operation while introducing a power saving mode with reduced power consumption to reduce power consumption in a standby machine. is there. That is, when the period of no input with the power on exceeds a predetermined time, the recording apparatus shifts to the power saving mode to reduce power consumption. When any instruction is input from the outside, a return operation is indicated and the operation mode is shifted again. An instruction input from the outside includes an instruction transferred from a host device connected to the recording apparatus, and an instruction generated by the recording apparatus itself upon detecting that an operation unit provided in the recording apparatus is operated. Including.

  In the return operation for returning from the power saving mode to the operation mode, the recording apparatus operates by taking over the operation state immediately before shifting to the power saving mode by connecting each unit to the power supply without executing the initialization operation. For this reason, unlike the power-on, the time from the start of the return operation to the start of the recording operation is short.

Patent Document 2 below describes control when returning from the power saving mode to the operation mode. As described in this document, when an external command is input during power saving, motor excitation, lighting of the panel backlight, etc. are resumed, and the state immediately before the transition to the power saving mode is recovered. Furthermore, as described in Patent Document 3 below, there is also an electronic apparatus in which a dedicated control device that controls the power saving mode is introduced to smoothly return to the operation mode.
JP 2000-326590 A Japanese Patent Laid-Open No. 2002-144777 JP 2006-201886 A

  As described above, the recording apparatus that has shifted to the power saving mode consumes less power and returns to the operation mode in a short time. For this reason, there are users who use the recording apparatus without shutting off the power supply for a considerably long period of time. In particular, in a commercial printer that uses a long and continuous recording medium, a large-capacity ink cartridge may be used, and the printer may continue to be used without shutting off the power supply.

  As described above, when returning from the power saving mode to the operation mode, the operation state immediately before the transition to the power saving mode is taken over, so that the same operation as when the operation mode is continued can be executed. Yes. However, in practice, if the recording apparatus is continuously operated by repeating the power saving mode and the operation mode without shutting off the power, the recording quality deteriorates, the wear of moving parts increases, the power efficiency decreases, etc. It turns out that problems arise.

  For the purpose of solving the above problems, as a first embodiment of the present invention, a feeding mechanism that takes in a plurality of loaded recording media one by one, and transports the loaded recording media in a transport direction along a predetermined transport path. Input from outside, a transport mechanism that moves the carriage that reciprocates the recording head in a direction that intersects the transport direction, a recording head that ejects ink to the recording medium transported along the transport path, An operation mode for recording an image on a recording medium in accordance with an instruction, and when the period without an instruction input from the outside continues for a predetermined time longer than the predetermined time, the other parts are detected except for a part for detecting the instruction from the outside. Standby in a state in which the power consumption is reduced by cutting off from the power supply, and when an external instruction is input, a power saving mode is executed to perform a return operation to return to the operation mode. A recording apparatus comprising a control unit for a row, the control unit, in return operation, a recording apparatus for executing the measurement procedure for measuring the operating conditions depend on the environmental conditions of the recording apparatus is provided. As a result, the performance of the recording apparatus does not deteriorate even if the recording apparatus continues to operate without repeating the power supply while repeating the power saving mode and the operation mode. In addition, it is possible to prevent a serious failure from occurring due to accumulation of operating condition defects caused by changes in environmental conditions.

  According to one embodiment, in the recording apparatus, the return operation includes an initialization operation of the feeding mechanism and the transport mechanism. Accordingly, even if a part of the feeding mechanism and the transport mechanism moves for some reason while waiting in the power saving mode, the feeding mechanism and the transport mechanism can be normally operated in the operation mode after the return. .

  According to another embodiment, in the recording apparatus, the plurality of transport paths include a manual path for loading recording media one by one without using a feeding mechanism, and an instruction input from the outside is a manual path. In the return operation, the initialization of the feeding mechanism and the transport mechanism is not executed, and a flag indicating that is set, and the recording paper staying in the recording unit When the paper is discharged, the feeding mechanism and the transport mechanism are initialized with reference to the flag. As a result, when the return operation is started by an instruction to use the manual feed path, when the return operation is started for the purpose of using the manual feed mechanism, the wasteful operation of initializing the feeding mechanism is saved. The return operation can be completed quickly. Further, when the feeding mechanism is used again, the transport mechanism can be operated under operating conditions that are suitable for the environmental conditions after the return.

  According to another embodiment, in the recording apparatus, the return operation includes a pressurizing operation for applying pressure to the ink ejected by the recording head. As a result, even if the pressure applied to the ink during standby in the power saving mode decreases, it is possible to prevent degradation of the recorded image due to insufficient pressure in the operation mode after the return.

  According to yet another embodiment, in the recording apparatus, when the instruction input from the outside is an instruction related to ink replenishment, the pressurizing operation is not executed. Accordingly, it is possible to avoid a wasteful pressurizing operation in the returning operation and quickly complete the returning operation started for the purpose of replacing the ink cartridge.

  According to another embodiment, in the recording apparatus, when the instruction input from the outside is an instruction to shut off the power supply of the recording apparatus, the end sequence of the recording apparatus is executed without executing the measurement procedure. Thereby, a useless return operation can be avoided, and the return operation started for the purpose of shutting down the power supply can be quickly completed.

  According to another embodiment, in the recording apparatus, the measurement procedure is included in the transport mechanism and includes a transport motor measurement that measures the actual load of the transport motor that operates the transport mechanism, and a carriage movement mechanism that moves the carriage. A carriage motor measurement for measuring the actual load of the carriage motor to be moved. As a result, even if the environmental conditions change while waiting in the power saving mode, the efficiency of the feeding motor, carriage motor, and conveyance motor can be prevented from decreasing, and the carriage movement amount and the recording medium conveyance amount can be accurately controlled. Can be controlled.

  According to another embodiment, in the recording apparatus, the plurality of transport paths include a manual path for loading recording media one by one without using a feeding mechanism, and an instruction input from the outside is a manual path. In the case of an instruction to use, the return operation does not execute the conveyance motor measurement, sets a flag indicating that, and refers to the flag when a recording medium is loaded in the manual feed path. Carriage motor measurement is executed. Thereby, when the return operation is activated by an instruction to use the manual feed path, useless conveyance motor measurement is omitted, and the return operation can be completed quickly. In addition, when the transport mechanism that has been used before shifting to the power saving mode is used again, the transport mechanism can be operated under operating conditions that are suitable for the environmental conditions after the return.

  According to another embodiment, in the recording apparatus, the plurality of transport paths include a board path for transporting a plate-shaped recording medium that cannot be bent, and an instruction input from the outside is an instruction to use the board path. In some cases, the return operation does not perform a transport motor measurement and a carriage motor measurement. As a result, when the return operation is activated by an instruction to use the board path, useless conveyance motor measurement and carriage motor measurement are omitted, and the return operation can be completed quickly.

  Furthermore, as a second aspect of the present invention, a feeding mechanism that takes in a plurality of loaded recording media one by one, a transport mechanism that transports the loaded recording medium in a transport direction along a predetermined transport path, and transport A liquid ejecting head that ejects liquid onto a recording medium transported along a path, a carriage moving mechanism that moves a carriage that reciprocates the liquid ejecting head in a direction crossing the transport direction, and a recording medium according to an instruction input from the outside When the operation mode for recording images on the camera and the period when there is no instruction input from the outside continues for a longer time than the predetermined time, the other parts are cut off from the power supply, leaving the part that detects the instruction from the outside. The control unit that executes the power saving mode for performing the return operation to return to the operation mode when an instruction from the outside is input in a standby state with reduced power consumption A liquid ejecting apparatus comprising a control unit, in return operation, the liquid ejecting apparatus to execute the measurement procedure for measuring the operating conditions depend on the environmental conditions of the liquid ejecting apparatus is provided. Thereby, the above-described effect can be enjoyed also in the liquid ejecting apparatus.

  The above summary of the invention does not enumerate all the necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the scope of claims, and all combinations of features described in the embodiments are included. It is not necessarily essential for the solution of the invention.

  FIG. 1 is a perspective view showing an appearance of an ink jet recording apparatus 100 having a power saving mode including a return operation to an operation mode as viewed obliquely from the front. As shown in the figure, the outer mold of the ink jet recording apparatus 100 is formed by a substantially rectangular parallelepiped case 101 as a whole.

  On the upper surface of the case 101, a feeding unit cover 110, a transport path cover 120, and an ink cartridge holder cover 130 are sequentially arranged from the rear end. The feeding unit cover 110 is opened in the direction indicated by the arrow C in the drawing with the rear end as a hinge by lifting the notch 112 with a finger. A feeding unit 310 (described later) appears inside the opened feeding unit cover 110. The transport path cover 120 and the ink cartridge holder cover 130 can also be opened according to arrows B and A shown in the drawing with the rear end as an axis. Inside the conveyance path cover 120, the path of the recording paper 250 being recorded appears. Thereby, maintenance work such as removing the recording paper 250 stagnating on the path can be performed. The ink cartridge holder cover 130 is formed so as to extend to the front surface of the case 101, and the ink cartridge 232 can be detached from the front surface of the ink jet recording apparatus 100 with respect to the cartridge holder 230 that appears when the case is opened.

  Further, a discharge portion cover 140 is formed below the ink cartridge holder cover 130 and a waste liquid cartridge cover 150 is formed on the right side of the discharge portion cover 140 on the front surface of the case 101. Each of the discharge unit cover 140 and the waste liquid cartridge cover 150 can be opened in the direction indicated by arrows D and E in the drawing with the lower end as a hinge. When the discharge unit cover 140 is opened, a discharge unit 340 for discharging the recorded recording paper 250 appears therein. Further, the waste liquid cartridge 152 can be replaced by opening the waste liquid cartridge cover 150.

  In addition, the ink jet recording apparatus 100 includes an operation panel 160 disposed at the front right end of the upper surface of the case 101. The operation panel 160 includes buttons 162 for directly operating the ink jet recording apparatus 100 and a liquid crystal panel 164 for displaying an operation state and the like. Accordingly, the user can operate the ink jet recording apparatus 100 in a stand-alone manner while checking the state on the liquid crystal panel 164.

  FIG. 2 is a perspective view showing an appearance when the ink jet recording apparatus 100 shown in FIG. 1 is viewed obliquely from the rear. As shown in the figure, on the upper surface of the case 101, a notch 122 that becomes a clue when opening the transport path cover 120 is visible. In addition, a manual path cover 170 is disposed on the back surface of the case 101. The manual feed path cover 170 can be opened according to an arrow F shown in the drawing with the lower end as a hinge. When the manual path cover 170 is opened, a path for manually feeding the recording paper 254 opens therein, and an arbitrary recording paper 254 can be loaded into the ink jet recording apparatus 100.

  FIG. 3 is a perspective view showing the internal mechanism 200 that appears when the case 101 is removed from the ink jet recording apparatus 100, as viewed from the same viewpoint as FIG. As shown in the figure, the internal mechanism 200 is formed in front of and behind a frame 220 extending in the longitudinal direction of the ink jet recording apparatus 100.

  A feeding unit 310 that is exposed when the feeding unit cover 110 is opened is disposed behind the frame 220. The feeding unit 310 includes a paper support 210 formed on the back surface of the feeding unit cover 110 and a hopper 212 disposed below the paper support 210. The paper support 210 supports the recording paper 250 loaded in a stacked manner from behind. The hopper 212 has a function of moving back and forth and pressing the uppermost recording sheet 250 against a feeding roller 312 described later.

  On the other hand, a transport unit 320, a platen 330, and a discharge unit 340 are sequentially arranged in front of the frame 220. A carriage 260 is disposed above the platen 330, and a cartridge holder 230 is disposed above the discharge unit 340.

  Here, the cartridge holder 230 is fixed to the front end of the frame 220. A plurality of ink cartridges 232 containing ink are attached to the cartridge holder 230. The mounted ink cartridge 232 individually contains, for example, seven colors of ink of photo black, matte black, gray, yellow, cyan, light cyan, magenta, light magenta, and red. Further, the ink cartridge 232 attached to the cartridge holder 230 communicates with the carriage 260 through a flexible tube (not shown) and supplies ink to the recording head 262 disposed on the lower surface of the carriage 260.

  On the other hand, the carriage 260 reciprocates over the entire width of the platen 330 along the guide shaft 280. The timing belt 270 disposed on the front surface of the frame 220 is stretched over a pair of pulleys (not shown) disposed near the side ends of the frame 220, and travels horizontally between the pulleys according to the rotation thereof. The carriage 260 is coupled to the timing belt 270 and driven.

  The waste liquid cartridge 152 attached to the front end of the right end of the frame 220 accommodates an absorbing member that absorbs ink discharged for the purpose of cleaning the nozzles by the carriage 260 at the home position located on the right side of the platen 330. As the operation time of the ink jet recording apparatus 100 becomes longer, the discarded ink is accumulated in the waste liquid cartridge 152. By exchanging the ink, the high absorption capacity can be maintained over a long period of time.

  FIG. 4 is a cross-sectional view of the internal mechanism 200 showing the conveyance path 300 of the recording paper 250 in the ink jet recording apparatus 100 including the internal mechanism 200 described above. As shown in the figure, the ink jet recording apparatus 100 is configured to load and insert a recording sheet 250 to be ejected of ink ejected from a recording head 262 mounted on the lower surface of a carriage 260 through a plurality of paths. Can be transported.

  It is assumed that the recording paper 250 loaded on the paper support 210 passes through the feeding unit 310, the conveying unit 320, and the discharging unit 340 and is discharged from the discharging unit 340 to the outside. Is a route to be done. In this path, with a plurality of recording sheets 250 loaded on the paper support 210, first, the lower end of the hopper 212 moves forward to press the uppermost recording sheet 250 against the feeding roller 312. The feeding roller 312 is rotationally driven by a motor (not shown), draws the pressed recording paper 250 downward, and then sandwiches it between the feeding roller 312 and the retard roller 314. At this time, since the lower end of the hopper 212 moves backward, the other recording paper 250 is separated from the uppermost recording paper 250 by the retard roller 314. Further, the other recording paper 250 drawn in with the fed recording paper 250 is returned to the paper support 210 by the return claw 311. Next, when the recording sheet 250 sent out by the feeding roller 312 reaches the conveyance unit 320, the peripheral surface of the D-shaped feeding roller 312 is separated from the recording sheet 250, and the conveyance of the recording sheet 250 is conveyed to the conveyance unit 320. Delivered.

  The conveyance unit 320 includes a conveyance driving roller 322 that is rotationally driven by a motor (not shown), and a conveyance driven roller 324 that is pressed against the conveyance driving roller 322 and rotated. The recording paper 250 inserted between the conveyance driving roller 322 and the conveyance driven roller 324 is pressed against the conveyance driving roller 322 rotated by the conveyance driven roller 324 and is sent onto the platen 330 according to the rotation of the conveyance driving roller 322. .

  The platen 330 supports the fed recording sheet 250 from below and positions the height thereof. In contrast, ink is ejected downward from the recording head 262 mounted on the lower surface of the carriage 260, and an image of ink is formed on the upper surface of the recording paper 250. The recording sheet 250 on which the image is formed further advances, and the front end eventually reaches the discharge unit 340.

  The discharge unit 340 includes a discharge drive roller 342 that is rotationally driven, and a pair of discharge driven rollers 344 that are pressed against the discharge drive roller 342 and rotated. The recording paper 250 sandwiched between the discharge driving roller 342 and the discharge driven roller 344 is pressed against the discharge driving roller 342 rotated by the discharge driven roller 344, and the ink jet recording apparatus 100 according to the rotation of the discharge driving roller 342. Sent to outside.

  Further, the ink jet recording apparatus 100 has a manual feed path that opens inside the manual feed path cover 170. That is, by opening the manual path cover 170 on the back of the case 101, the recording paper 254 can be loaded directly in front of the transport unit 320. As a result, an image is recorded on an arbitrary recording paper 254 that is temporarily used, different from the recording paper 250 loaded in the paper support 210, as in the case of the recording paper 250. Drain to the front of 100.

  Further, the ink jet recording apparatus 100 has another path that can record an image on thick paper, board paper, or the like that cannot be bent. The board path includes a gap between the recording head 262 and the platen 330 and is formed horizontally. When using the board path, a board paper tray (not shown) provided inside the discharge unit cover 140 is pulled out, and the recording medium 256 is loaded therefrom.

  Note that this type of recording medium 256 has a high bending rigidity, and if it is bent in the path, the transport load increases significantly. Therefore, when the board path is used, the transport driven roller 324 is retracted upward and is inserted through the horizontal path 258 formed below the paper support 210. That is, by pulling out the board tray, the operation of the discharge unit 340 is reversed. Accordingly, the recording medium 256 is moved backward until the front end of the recording area on the surface of the recording medium 256 reaches below the recording head 262. Next, the discharge unit 340 is returned to the normal rotation, and the recording medium 256 is sent forward while recording an image.

  As described above, the conveyance path 300 of the ink jet recording apparatus 100 includes a plurality of paths, and can be used depending on the characteristics of the recording paper 250 and 254 or the recording medium 256. Further, the operations of the feeding unit 310, the transport unit 320, and the discharge unit 340 are also different depending on the route used.

  The ink jet recording apparatus 100 also includes a control unit 360 that controls the operation of the ink jet recording apparatus 100 on the back side of the lower end of the frame 220. The control unit 360 performs control so that an appropriate operation is executed based on an instruction input via an information processing apparatus connected to the ink jet recording apparatus 100 or an instruction input from the operation panel 160. . The control unit 360 is also an interface that receives image information to be recorded. The image information received by the control unit 360 may include recorded object information such as recording quality such as resolution and number of colors, dimensions, and materials in addition to information representing the image.

  The control unit 360 also controls transition to a power saving mode described later. That is, when the signal is not input to the ink jet recording apparatus 100 and the operation panel 160 is not operated exceeds a predetermined time, the backlight of the liquid crystal panel 164 is turned on, leaving a circuit for receiving an instruction from the outside. To reduce power consumption. For this reason, the appearance is almost the same as when the power supply is shut off. Also in the internal mechanism 200, the excitation of each motor is stopped. Furthermore, since the pressurization to the ink cartridge 232 is also stopped, the pressure in the cartridge gradually decreases with time.

  Note that if any instruction is input from the outside during the power saving mode, it is detected and a return operation for returning the ink jet recording apparatus 100 to the operation mode is started and executed. The instruction input from the outside here is an instruction signal transferred from a host device connected to the ink jet recording apparatus 100, an operation on the operation panel 160, any cover formed on the case 101, for example, In addition, opening the ink cartridge holder cover 130 and the waste liquid cartridge cover 150 is also included.

  In the return operation, each part of the internal mechanism 200 is connected to the power supply, and processing for restoring the state immediately before the transition to the power saving mode is also executed. However, since it takes a long time to perform all initialization operations when the power of the ink jet recording apparatus 100 is turned on, the advantage of introducing the power saving mode is lost. Therefore, in the return operation, processing is executed according to a unique procedure described below.

  FIG. 5 is a flowchart F <b> 100 showing a procedure executed first when some instruction is input from the outside to the inkjet recording apparatus 100 in the power saving mode and detected by the control unit 360. As shown in the figure, when the control unit 360 detects an instruction input from the outside (step S101), the control unit 360 determines whether the instruction is an instruction to shut off the power of the ink jet recording apparatus 100 (step S101). S102).

  If the input instruction is an instruction to shut off the power supply of the entire inkjet recording apparatus 100 (step S102: YES), the recovery of the operation mode is meaningless, so the end sequence is started without executing any return operation. (Step S103), the power supply of the ink jet recording apparatus 100 is shut off. Thereby, the power supply can be quickly shut down from the power saving mode. On the other hand, when the input instruction is an instruction for causing the ink jet recording apparatus 100 to perform the recording operation (step S102: NO), the return operation is started (step S200), and the processes described below are sequentially executed. Note that the processing shown in FIG. 6 and the processing shown in FIG. 7 can be processed in parallel independently of each other. Thereby, the time until the return operation is completed can be shortened.

  FIG. 6 is a flowchart F210 showing a control procedure of processing relating to the ink cartridge, which is executed in the return operation. As shown in the figure, when the return operation is started (step S211), it is checked whether or not the cartridge cover that opens and closes when the ink cartridge 232 is replaced is closed (step S212).

  Here, when the cartridge cover is open (step S212: NO), the initial pressurization of the ink cartridge 232 is not executed. On the other hand, when the cartridge cover is closed (step S212: YES), the initial pressurization to the ink stored in the ink cartridge 232 is executed. Thus, the return operation for the ink cartridge 232 is completed.

  FIG. 7 is a flowchart F220 showing a control procedure regarding the moving mechanism of the feeding section 310, the transport section 320, and the carriage 260, which is executed in the return operation. As shown in the figure, in the return operation related to the conveyance path 300 of the recording paper 250, first, an instruction input from the outside to start the return operation (step S221) is an operation using the manual feed path. It is checked whether the instruction is related to (step S222).

  Here, when the operation related to the instruction for starting the return operation does not use the manual feed path (step S222: NO), it is checked whether or not the feeding unit 310 is at the origin position (step S223). If it is not at the origin position (step S223: NO), the feeding unit 310 and the conveying unit 320 are initialized (step S224), and then the process proceeds to the next step (S225). Thereby, even when the state of the feeding unit 310 and the transport unit 320 has changed for some reason while waiting in the power saving mode, the feeding operation and the transport operation are accurately controlled in the operation mode after returning. it can. On the other hand, if it is at the origin position (step S223: YES), the next step (proceeds to S225) is performed without executing initialization.

  Next, it is checked whether or not the operation related to the input instruction uses the board route (step S225). When the operation related to the instruction uses the board path (step S225: YES), the return operation is finished as it is (step S228), and the recording medium 256 that cannot be bent such as cardboard or the disk tray 156 is loaded. Wait for On the other hand, when the input instruction does not use the board route (step S225: NO), the carriage motor measurement (step S226) and the conveyance motor measurement (step S227) are sequentially executed. Thus, even when the environmental condition changes while waiting in the power saving mode, it is possible to measure the environmental condition after the return and execute appropriate control. Thus, the state in which the mechanism related to the transport path 300 can be accurately controlled is recovered, and the recovery operation can be terminated (step S228).

  Note that environmental conditions such as the temperature, humidity, and inclination of the installation location of the environment in which the ink jet recording apparatus 100 is installed may change while the ink jet recording apparatus 100 is on standby after entering the power saving mode. is there. Accordingly, the actual load measured according to the environmental conditions of the transport motor and the carriage motor 255, for example, measured at the time when the power of the ink jet recording apparatus 100 is turned on may not be appropriate when returning from the power saving mode. is there. Therefore, when the operation related to the actual load of each motor is executed in the operation mode after the return operation, it is preferable to execute the measurement in the return operation.

  On the other hand, if the instruction that triggered the return operation is an instruction related to the operation using the manual feed path (step S222: YES), initialization of the feeding unit 310 and the conveying unit 320, In addition, the return operation is finished without executing the conveyance motor measurement and the carriage motor measurement (step S237), in preparation for the start of the manual printing recording operation (step S239).

  However, in this case, a process for setting a flag indicating that initialization of the feeding unit 310 and the conveyance unit 320 has not been executed yet (step S233) and a flag indicating that the carriage motor measurement has not been executed yet. The process of standing (step S235) is executed. Thus, initialization and measurement are executed at an appropriate timing when performing manual feed printing.

  That is, when the recording paper 250 staying on the transport path 300 is discharged for performing manual feed printing, the feeding unit 310 and the transport unit 320 are initialized. Further, when the recording paper 254 is loaded into the manual feed path, carriage motor measurement is executed. Thus, precise control can be performed according to the immediate environmental conditions at which manual feed printing is started.

  As described above, the ink jet recording apparatus 100 performs initialization of the feeding unit 310, the transport unit 320, the carriage moving mechanism, and the measurement of the transport motor and the carriage motor in the return operation. Thus, accurate control after the return can be ensured regardless of the change in the state of each part during standby in the power saving mode and the change in environmental conditions. In addition, since appropriate processing is executed according to the type of instruction that triggered the return from the power saving mode, the execution time of the return operation is not prolonged.

  As described above, when the return operation is started in the power saving mode, the ink jet recording apparatus 100 initializes the initial pressurization of the ink, the transport mechanism, the carriage movement mechanism, and the like according to the type of the start trigger. Of the various measurements, the procedure effective for the subsequent operation mode is selectively executed. As a result, the completion of the quick return operation, the reduction of the load on the device, and precise control are both achieved.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment.
