Example implementations relate to adjusting print medium retrieval. For example, a system may include a printing device that may have a pick roller attached to a pick arm and a servomotor to apply torque to the pick roller. The system may further include a controller associated with the servomotor to determine a measured position of the servomotor relative to an intended position of the servomotor in a particular time frame during the print medium retrieval. The controller may further determine adjustment of the print medium retrieval based on comparison of a pulse width modulation (PWM) magnitude in adjacent time frames.

An image forming apparatus includes a feeding apparatus feeding a recording material and a protruding member that protrudes downward from an apparatus main body; wherein when the feeding apparatus is installed below the apparatus main body, the protruding member is provided in a bottom portion of the apparatus main body so that inside the feeding apparatus the protruding member does not come into contact with a movable unit which is provided in the feeding apparatus so as to be movable with respect to the feeding apparatus, and the protruding member is positioned on an outer side of a feeding path of the recording material in the feeding apparatus, and moreover the protruding member penetrates more inward than an external surface of the feeding apparatus from above the feeding apparatus.

The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.

A printer according to an embodiment includes a printing unit that prints on a sheet. The sheet is discharged through an outlet. The sheet is conveyed on a sheet conveyance path through the printing unit and to the outlet. A movable device is located on the sheet conveyance path upstream of the outlet in a sheet conveying direction. The movable device can move between a separation position, a proximity position, and a protruding position. A detection device detects a position of the movable device. A controller determines a conveyance abnormality of the sheet based on the state of the movable device detected by the detection device, and outputs a signal indicating the conveyance abnormality.

An image forming apparatus includes a stacking unit, an access detecting unit, a malfunction detecting unit, a counting unit, and a process deciding unit. The stacking unit receives, as stacked, a recording material. The access detecting unit detects an access to the stacking unit by an operator. The malfunction detecting unit detects that a conveyance malfunction of the recording material has occurred on a conveying path guiding the recording material supplied from the stacking unit. The counting unit counts, after the access detecting unit detects an access to the stacking unit by the operator in a state that the malfunction detecting unit does not detect that the conveyance malfunction has occurred, the number of the conveyance malfunction detected by the malfunction detecting unit. The process deciding unit decides a process to address the conveyance malfunction based on the number of the conveyance malfunction counted by the counting unit.

A medium feeding device includes a medium placing portion, a feeding roller that feeds paper, a medium movement detecting portion that is positioned on a placing region of the paper of the medium placing portion in a medium feeding direction and is capable of detecting movement of the paper being fed in a width direction intersecting the medium feeding direction, and a controller that stops feeding of the paper in a case in which a physical quantity relating to movement of paper in the width direction exceeds a predetermined threshold based on a detected result by the medium movement detecting portion.

A feeding apparatus includes a feeding rotary member, a conveying rotary member pair, an output unit, a detection unit, and a control unit. The conveying rotary member pair includes first and second rotary members. The control unit stops a feeding operation when the detection unit does not detect the recording material by the time when a threshold time has elapsed after an operation of feeding a recording material is stated. The control unit determines that the recording material is stopped at a position on an upstream side relative to the nip portion in the feeding direction in a case where a rotation speed of the second rotary member, indicated by a state signal output from the output unit at least in a period of time from when the recording material reaches the nip portion to when the feeding operation is stopped, is faster than a threshold speed.

A medium feeding device includes a medium placing portion, a feeding roller that feeds paper, a medium movement detecting portion that is positioned on a placing region of the paper of the medium placing portion in a medium feeding direction and is capable of detecting movement of the paper being fed in a width direction intersecting the medium feeding direction, and a controller that stops feeding of the paper in a case in which a physical quantity relating to movement of paper in the width direction exceeds a predetermined threshold based on a detected result by the medium movement detecting portion.

An image forming apparatus including: a printer; a puncher configured to punch the sheet printed by the printer; a binder configured to perform a bookbinding process to form a bound product in which a binding member penetrates punch holes of sheets; a first detector configured to detect a first jam of a sheet in the binder; a second detector configured to detect a second jam of a sheet which occurs upstream of the binder; an annunciator configured to notify information; and a controller configured to cause the annunciator to notify first instruction information for instructing removal of a sheet and the binding member, when the first detector has detected the first jam; and cause the annunciator to notify second instruction information for instructing removal of the second jam when the second detector has detected the second jam and the first detector has not detected the first jam.

A recording apparatus which is capable of suppressing or avoiding a concern on a defect such as a paper jam, deterioration of recording quality, or the like at the time of performing an overlapping transportation is provided.
