Bypass Jam
“BYPASS JAM” appears in the display when the machine does
not detect paper in the bypass tray due to no paper or improper
paper loading when you try to print using the bypass tray.
“BYPASS JAM” also may occur when the paper is not properly fed
into the machine through the bypass tray. In that case, pull the
paper out of the product.
