Sheet conveying device, image forming apparatus, sheet conveying motor control system, and storage medium

A non-transitory computer-readable storage medium storing program code for causing a sheet conveying device to perform a method,

• wherein the sheet conveying device includes a first rotator, a second rotator, and a third rotator, at least one of which being configured to convey a sheet medium,
• the method comprising:
• detecting a first control factor for controlling a first motor that rotates the first rotator;
• detecting a second control factor for controlling a second motor that rotates the second rotator;
• and
• changing a rotational speed of a third motor for rotating the third rotator based on a sum of the first control factor and the second control factor.

A system, comprising:

• a sheet conveying device including a first rotator, a second rotator, and a third rotator, at least one of which being configured to convey a sheet medium;
• and
• a computer connected to the sheet conveying device, wherein
• the sheet conveying device further includes
• a first detection unit configured to detect a first control factor for controlling a first motor that rotates the first rotator,
• a second detection unit configured to detect a second control factor for controlling a second motor that rotates the second rotator, and
• a motor control unit configured to control a rotational speed of a third motor that rotates the third rotator;
• and
• the computer includes
• a speed control unit configured to request the motor control unit of the sheet conveying device to change the rotational speed of the third motor based on a sum of the first control factor and the second control factor.
