Missing Band in Direction of Paper Travel, All Colors
There are areas of the image that are
extremely light or are missing entirely.
These missing areas form wide bands
from leading edge to trailing edge
(B-size print shown). The printer
displays no error code.
Note
A-size prints are processed
through the printer with the short
edge of the print parallel to the
direction of the paper path, making
print artifacts parallel to the short
edge of the print.
