This product is aimed at all those who print a lot, or in which the paper size often changes. You can use A4 paper in the second drawer DIN and in the main compartment you can use all other paper sizes. If you want to use this trade as an additional A4 paper tray you have to change anything on the printer, because if one tray is empty, is automatically accessed to the other tray. If you would like to take this subject for a different paper size, you can select the default tray of the printer and the printer driver, and then only one of the two compartments is used and when the default tray is empty then, is not connected to the other tray.
The printer is also very stable in this subject, because the subject has the same basic dimensions as the printer.
I am glad to have bought me this extension and do not want to miss it.
