6.3 Maximum dpi
The Maximum dpi print quality setting offers 4800 x 1200 optimized dpi printing.
The 4800 x 1200 optimized dpi print mode is the highest quality resolution for this
printer. When 4800 x 1200 optimized dpi is selected in the printer driver, the tri-color
print cartridge prints in the 4800 x 1200 optimized dpi mode (up to 4800 x 1200
optimized dpi color and 1200-input dpi).
Follow these steps to print in the 4800 x 1200 optimized dpi mode:
1. Open the Print dialog box.
2. Select the Paper Type/Quality panel.
3. In the Paper Type drop-down list, select Photo Paper, and then click the
appropriate photo paper type.
4. In the Quality drop-down list, click Maximum dpi.
5. Select any other print settings that you want, and then click Print.
6.4 Photo print cartridge
The photo print cartridge, used in conjunction with the tri-color print cartridge,
provides six-ink, virtually grain-free photos that have exceptional fade resistance.
