the MP tray. Press the scroll buttons on the
operator panel several times to select
[Configuration] - [Paper Feed Roller Counter],
and check the roller usage of each tray and
replace the paper feed roller if the service life
has reached.

tray from [Paper Source] in the printer driver.
Disable [Feed paper individually] in the printer
driver.
Set up Tray 2/3/4 in the printer driver.

to select [Menus] - [Print Adjust] - [High Humid
Mode], and change the setting.
