Not Correctly Detecting the Absence of Ink
The mechanisms of the product are designed in such a way that the following
operations can at times prevent the correct detection of the absence of ink, not printing
NOTE received images and, as a result, generating a blank output.
• While ink is present, the flatbed ass'y is opened, the ink tank is removed, and the
flatbed ass'y is closed without putting back the ink tank.
• While ink is present, the flatbed ass'y is opened, the ink tank is removed, and the
flatbed ass'y is closed after improperly putting back the ink tank (i.e., without hearing
a clicking sound).
• While ink is present, the flatbed ass'y is opened, and the flatbed ass'y is closed after
fitting an ink tank whose ink chamber is empty.
