The Canon PIXMA G640 is a refillable ink tank printer that combines high-volume printing with exceptional photo quality in a 3-in-1 print, scan, and copy package. As the first multi-function model in Canon’s PIXMA G range to feature six dye-based ink tanks, it delivers richer colors, deeper contrast, and cost-efficient operation for homes, home offices, and small businesses. With Wi-Fi connectivity and a compact footprint, it integrates easily into any workspace where quality and efficiency matter.

Six Ink Tanks for Superior Photo Quality

The G640 uses a six-color ChromaLife100 dye ink set that includes dedicated red and grey inks alongside standard black, cyan, magenta, and yellow . The red ink expands the color gamut for richer, more vibrant tones, while the grey ink improves contrast in dark areas and ensures consistent color reproduction across different photo papers. Prints are rated to last up to 100 years when stored in a photo album using Canon Photo Paper Plus Glossy II, making this printer a reliable choice for preserving memories and producing professional-quality photo prints.

Exceptional Print Resolution

With a maximum print resolution of 4800 x 1200 dpi, the G640 produces sharp text, smooth gradients, and finely detailed images . Ink droplets can be placed with a minimum pitch of 1/4800 inch, ensuring precision across every print. Whether you are printing documents, marketing materials, or borderless photographs up to A4 size, the output is consistently clean and professional.

High-Yield Refillable Ink System

One of the G640’s defining advantages is its economical refillable ink tank system. A single set of ink bottles can produce up to 8,000 A4 color documents or 3,800 4×6-inch photographs, dramatically reducing the cost per page compared to cartridge-based printers . The keyed ink bottles are designed for error-free refilling, with color-coded caps and shaped inlets that only accept the correct bottle. No squeezing is required, and the bottles automatically stop injecting ink when the tank is full.

Scan and Copy Functionality

The G640 is a true 3-in-1 device. Its CIS flatbed scanner offers an optical resolution of 600 x 1200 dpi, suitable for documents, photos, and everyday scanning tasks . Copy functions include document and photo copying, borderless copy, 2-on-1 and 4-on-1 copy, frame erase, and ID copy. Copy speeds are approximately 25 seconds for the first copy out, with a maximum of 99 copies per job and zoom range from 25 to 400 percent.

Wireless Connectivity and Mobile Printing

Wi-Fi connectivity (IEEE 802.11 b/g/n on 2.4 GHz) enables printing from laptops, smartphones, and tablets without cables . The G640 supports the Canon PRINT Inkjet/SELPHY app, Apple AirPrint, Mopria for Android, and Wireless Direct for router-free connections. PIXMA Cloud Link allows printing from social media and photo-sharing platforms directly from mobile devices. A two-line monochrome LCD display provides clear status information and easy setting adjustments.

Ideal Use Cases

This printer is well-suited for home users who print photos and documents regularly, home offices needing reliable all-in-one functionality with low running costs, small businesses producing marketing materials and client deliverables, photography enthusiasts wanting high-quality photo prints with lasting color, and students or families requiring affordable high-volume printing for assignments and projects.
