Solution
Perform the Bottom Plate Cleaning to clean the inside of the machine.
REFERENCE
When performing borderless printing, duplex printing, or too much printing, the inside may become stained with ink.
Remove stains from the inside of the machine. If the inside of the machine becomes dirty, printed paper may get dirty, so we recommend performing cleaning regularly.
