Missing Print
1. Hold a light-colored, absorbent towel under the front of the print head to catch potential ink overflow. The light-colored towel will reflect light,
making the face of the print head easier to see.
2. Press and hold the
ACS/Prime
button for five (5) seconds until the S
MART
-IDS beacon light flashes once. Observe the 1-second ink flow out
of the print head.
3. Inspect for very small air bubbles flowing out of the top of the print head and down the face. If bubbles are evident, repeat steps 1 to 3 three
times.
4. Perform an ACS cycle, then slowly swipe a sheet of paper in front of the print head while pressing the
All Channel Print
button on the rear of
the print head.
5. If any print is still missing after all air bubbles are purged, recap the print head, perform several Prime cycles, decap, and repeat the ACS.
6. Repeat the above steps as necessary.
