7104 Series at a Glance

Best Fit
The 7104 Series is a true production commitment, not just a bigger office machine.
Buyers here are usually running mail as a dedicated daily job with its own space, staffing, and uptime expectations, not squeezing it in around other office work.
This is a larger footprint and investment than the 6000-class lineup, so it's worth a real workflow review before committing.
Good fit if you are mailing:
- Recurring high-volume mail regularly above 80,000 pieces a month
- Complex jobs needing up to 17 feed stations across 8 modules
- Glossy paper or booklets up to 4mm thick alongside standard sheets
- Applications needing intelligent OMR/barcode/Data Matrix reading
Consider the 6608 Series instead if:
- Monthly volume is closer to 80,000 pieces or below
- Up to 7 feed stations covers your document mix
- You want a smaller footprint without a full production line
- An output conveyor and 22" touchscreen are more than your job needs
