The printer has two paper trays. You can load A3 paper in the lower paper tray and leave it loaded. To do this, however, the paper tray (drawer) must be "extended". The only disadvantage is that if the lower drawer is extended and the A3 paper is left in it, the drawer protrudes by about 8 cm. This looks a bit "unattractive", but is otherwise not a problem.
All in all, this printer is certainly worth its price!

When setting up, it is important to define the paper format for the corresponding tray. Then select A3 when printing.
