Print Head
This product employs the µTFP4 head.
The µTFP4 head features dense nozzle pitches (600 dpi). In addition, the number of nozzles per row is also greater with the row length of 1.33 inches.
These features contribute to higher image quality and faster printing by increasing both the quantity and the density of ink droplets per shot.
The following table lists the Printhead specifications.
| Printhead type | µTFP4 |
|---|---|
| Color | Black (B: 2 row) Cyan (C: 2 row) Magenta (M: 2 row) Yellow (Y: 2 row) |
| Number of nozzles | 3200 nozzles (400 nozzles per row) |
| Nozzle pitch | 0.042 mm (1/600 inch) |
The nozzle arrangement of the μTFP4 head mounted on this printer differs from that of the traditional printers. The nozzles of the same color are not arranged next to each other.
The nozzle layout as seen from behind the Printhead is shown below.
| Row A | Row B | Row C | Row D | Row E | Row F | Row G | Row H |
|---|---|---|---|---|---|---|---|
| Yellow | Cyan | Magenta | Black | Black | Magenta | Cyan | Yellow |
This product uses off-carriage type ink supply mechanism.
Therefore, the Print Head is equipped with self-sealing valves so that the amount of ink fired from the Print Head is not affected by variation in pressure inside the ink path caused by movements of the carriage or ink supply operations.
