An openable cover automatic opening mechanism includes a lever rotatable about a rotation fulcrum, a locking section that is positioned at one end of the lever and that maintains the openable cover, which is in a closed state and which receives an opening force, in the closed state by locking with the openable cover, and a power receiving section positioned at the other end of the lever for contacting the horizontally moving carriage to receive power of the carriage. The lever rotates when the carriage comes into contact with and presses the power receiving section, and releases maintenance of the closed state of the openable cover by the locking section.

A medium feeding device includes a feeding roller that is provided in a medium feeding path through which a medium is fed and that feeds a medium downstream by rotating in the forward direction in response to power of a motor, a nip roller that is provided in the medium feeding path and that nips a medium in cooperation with the feeding roller and rotates, and a controller configured to control the motor. Based on an increase in a variation value varying in accordance with a drive load of the motor, the controller controls the motor and causes the feeding roller to start a medium feeding operation.

Medium feeding device and recording apparatus

A medium-discharging device includes: a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; a light-emitting section that emits light to the medium-receiving tray; and a control section that controls the light-emitting section, in which the medium-receiving tray is configured to switch between a first state in which the medium-receiving tray is stored in an apparatus main body that includes the medium-discharging section and a second state in which the medium-receiving tray protrudes from the apparatus main body, and the control section controls the light-emitting section in accordance with a state or operation of the medium-receiving tray.

Medium-discharging device and recording apparatus

The recording device includes an upstream transport roller pair capable of transporting a medium, a recording head configured to record an image by discharging ink at a predetermined timing on the medium transported downstream in a Ddirection by a predetermined transport amount by the upstream transport roller pair while moving in a Y-axis direction intersecting the Ddirection, an image capturing unit configured to read the image recorded on the medium by the recording head, and a control unit, wherein the control unit has a function of performing maintenance for a discharge failure of the ink, a correction of the transport amount, and a correction of the discharge timing of the ink based on the reading result of the image read by the image capturing unit.

A medium transport device includes a feeding roller that feeds a recording medium, a transport roller that transports the recording medium toward a recording head, and a transport motor which is a common driving source for the feeding roller and the transport roller. The medium transport device includes a power transmission mechanism that transmits power of the transport motor to the feeding roller, and a control section that controls a current of the transport motor. The control section measures a current value flowing through the transport motor during driving as a measured current value, and adds a predetermined offset value to the measured current value to set a second limit value as a limit value of the current supplied to the transport motor.

Medium transport device, recording apparatus, and control method of medium transport device

A recording device includes a recording head, a transport roller set, and a controller that controls a driving source that drives a transport driving roller. The controller judges whether a rear end that is an upstream end of a medium in a transport direction crosses a kicking region set in a range present downstream of a nipping position of the transport roller set in a transport direction. When the controller judges that the rear end does not cross the kicking region, the controller adjusts a feeding amount for at least one of a plurality of transport operations to be performed until the rear end reaches the kicking region in such a manner that the rear end of the medium crosses the kicking region.

Recording device and method for controlling recording device

A recording device and control method execute a printhead retraction operation at an appropriate speed when a paper jam occurs, make removing jammed paper easy, and prevent problems from pieces of paper left inside the recording device. The printerretracts the head carriageto the home position HP or away position AP when a paper jam occurs. The retraction distance is calculated, and a retraction speed determined based on a speed control table. If the retraction speed is low, there is little chance of pulling on the jammed paper P and making removal of the jammed paper P difficult. If the retraction distance is long, changing retraction speed to a high speed during the retraction operation shortens time of the retraction operation. Therefore, there is little chance of the user tearing the jammed paper P, and little chance of problems caused by pieces of paper left inside.

Recording device and control method therefor

When a paper jam occurs while printing, the control unit of a printerretracts the head carriageat a slow speed (initial retraction speed V), and retracts the head carriageat the slow speed to the target retraction position if the access coveris not opened. If the access coveris opened during retraction, the speed of head carriagemovement is changed to a faster retraction speed (high retraction speed V). If the head carriageis retracted quickly when the access coveris opened, there is little chance of a user that wants to quickly restore printeroperation catching the stuck paper P on the printheadand tearing the paper P. There is therefore little chance of problems resulting from torn pieces of paper being left inside the printer

A control method of a serial printer enables easily removing the printing paper when a paper jam occurs, and can prevent or suppress damage to the printhead when removing the printing paper. A serial printerconveys printing paper P by a conveyance mechanismincluding a second paper feed roller pairlocated upstream from the print position A in the first conveyance direction M1. If a paper jam of the printing paper P is detected when the printheadis at a position opposite the horizontal conveyance path portionof the paper conveyance path, conveyance of the printing paper P first stops, and the printheadis then moved on the vertical axis Z away from the horizontal conveyance path portion. Next, the printheadis moved on the transverse axis X to a away positionAW outside the horizontal conveyance path portion, and nipping of the printing paper P by the second paper feed roller pairis then released.
