The option for 2-Sided Printing (Windows) or Two-Sided Printing Settings (Mac) is gray or not available. What should I do?
Make sure you use a paper type and size that supports this feature. Automatic double-sided printing is only available if you select plain paper and these paper sizes in the printer software:
- Letter (8.5 x 11 inches [216 x 279 mm])
- A4 (8.3 x 11.7 inches [210 x 297 mm])
Note: Automatic double-sided printing is not supported on glossy, thick, and certain matte papers.
