1. Design & Build Quality

Canon designed both printers with a modern, compact appearance despite their business-oriented feature set. Both come in a clean white finish that fits nicely into a home office or professional workspace. Their space-saving design allows them to fit comfortably on desks or cabinets without taking up excessive room.

Both models feature an easy-to-access front ink tank system, making it simple to monitor ink levels and refill bottles without creating a mess. Canon’s bottle design also minimizes accidental spills by ensuring each bottle only fits into the correct tank.

The main physical difference is size and weight. The GX7120 weighs 28.6 pounds, while the GX6120 is slightly lighter at 25.6 pounds due to the additional fax hardware inside the GX7120.

2. Print Quality & Performance

Printing performance is identical on both printers.

Both use Canon’s MegaTank inkjet technology to produce sharp black text and vibrant color documents. Whether you’re printing invoices, reports, presentations, marketing materials, or school assignments, both deliver excellent quality.

Print speeds are also the same:

• Black: 24 pages per minute
• Color: 15.5 pages per minute

These speeds are fast enough for busy offices with moderate to heavy daily printing needs.

Since both printers use the same print engine, users won’t notice any difference in print quality or speed.

3. Scanning, Copying & Fax

Both printers include:

• Flatbed scanner
• Automatic Document Feeder (ADF)
• High-quality copying
• Multi-page scanning

The GX7120 adds one major feature:

• Built-in Fax

This makes the GX7120 more suitable for offices handling contracts, healthcare forms, insurance paperwork, legal documents, or government communications.

For users who never send or receive fax documents, this feature may never be used.

4. Ink System & Running Costs

One of the biggest advantages of Canon’s MegaTank printers is their incredibly low printing cost.

Both printers include enough ink to print for up to two years under Canon’s estimated monthly printing volume. Instead of replacing expensive cartridges, users simply refill the integrated ink tanks using inexpensive ink bottles.

This dramatically lowers the cost per page compared to traditional inkjet printers.

Both printers offer identical running costs.
