Configuring Custom Sizes
To print on custom size paper loaded in trays 1 to 4, you must 
set the paper size on the control panel. Use the Menu to set Auto-
Sense OFF and then set Custom Size for the intended tray.
You may also need to set it in the printer driver, depending on 
the paper size. See the description of Express Print for an easy way to 
print on various Custom Sizes.
Caution!
When setting the paper size in the printer driver and control 
panel, be sure to specify the same size as the actual paper 
used. Setting the wrong size for printing will cause printer 
failure. This is especially true if you configure a bigger size 
when using a narrow width paper. 
Note
To return to standard paper size settings, select [Auto]. The 
printer will automatically detect the size and orientation of 
the loaded paper.
