After narrow paper (i.e. width A in the figure) had been printed on repeatedly, wide paper was printed on.

If this occurs when you load the paper in landscape orientation, try printing with the paper loaded in portrait orientation.

You can reduce the occurrence of a difference in density by changing the settings of this machine as follows.
Press the scroll buttons on the operator panel several times to select [Menus] - [Print Adjust] - [Paper Black Setting], and change the setting to [-1].

It may take some time to improve the problem. If the problem does not improve even after the setting is changed, leave this machine idle for a while.
