Recording device and control method

1 . A recording device configured to perform recording on a recording medium, comprising:

a recording unit configured to perform the recording by ejecting ink onto the recording medium;

a medium transport belt configured to transport the recording medium on which the recording is to be performed by the recording unit;

a charging unit configured to charge the medium transport belt;

a detection section configured to:

detect a charging condition of the charge of the medium transport belt; and

acquire, as the charging condition, one of a maximum charging current or an average charging current based on a rotation of the medium transport belt a specific number of times;

a cleaning unit configured to move to a contact position at which the cleaning unit is in contact with the medium transport belt or a non-contact position at which the cleaning unit is not in contact with the medium transport belt, and to perform a cleaning operation on the medium transport belt when the cleaning unit is positioned at the contact position;

a discrimination section configured to discriminate a surface state of the medium transport belt based on the acquired charging condition by the detection section; and

a control section configured to cause the cleaning unit to execute the cleaning operation according to the surface state of the medium transport belt discriminated by the discrimination section.

2 . The recording device according to claim 1 , wherein the control section is configured to change the cleaning operation by adjusting an execution time of the cleaning operation.

3 . A recording device configured to perform recording on a recording medium, comprising:

a recording unit configured to perform the recording by ejecting ink onto the recording medium;

a medium transport belt configured to transport the recording medium on which the recording is to be performed by the recording unit;

a cleaning unit configured to move to a contact position at which the cleaning unit is in contact with the medium transport belt or a non-contact position at which the cleaning unit is not in contact with the medium transport belt, and to perform a cleaning operation on the medium transport belt when the cleaning unit is positioned at the contact position;

a discrimination section configured to:

receive a print job including print data and printing conditions,

wherein the print data is data corresponding to one sheet of the recording medium, and the printing conditions include at least one of a size of the recoming medium, a single-sided/double-sided print, or a type of the ink to be ejected; and

discriminate a surface state of the medium transport belt based on the print job; and

a control section configured to cause the cleaning unit to execute the cleaning operation according to the surface state of the medium transport belt discriminated by the discrimination section.

4 . The recording device according to claim 3 , wherein

the control section moves the medium transport belt when the cleaning unit executes the cleaning operation, and

a first condition and a second condition include a movement speed of the medium transport belt.

5 . The recording device according to claim 4 , wherein

the movement speed included in the first condition is a first speed, and

the movement speed included in the second condition is a second speed slower than the first speed.

6 . The recording device according to claim 3 , wherein

the cleaning unit includes a cleaning material in contact with the medium transport belt, and is configured to transport the cleaning material by using a cleaning material transport mechanism, and

a first condition and a second condition include a transport amount of the cleaning material.
