Is this the right printer for you?

Who the Canon imageRUNNER ADVANCE DX 6855i is actually for

Most equipment pages just tell you what a device does. Here's the honest version: when this machine is the right choice, when it's fine, and when you should look at something else. We offer equipment for every business need, but the right machine depends on your specific workflow.

Best fit

Pick this if...

  • You run a workgroup of 20-60 people that needs A3 (11x17) and 12x18 monochrome output in-house.
  • You print 5,000-15,000 pages a month and want a current-generation iR-ADV DX (256 GB SSD, 5 GB RAM, Trellix runtime intrusion detection).
  • You scan stacks of mixed-size originals daily — the 200-sheet single-pass DPF runs 270 ipm in duplex, fast enough to keep an operator from waiting.
  • You want native cloud connectors (Google Drive, Box, Dropbox, OneDrive) and Universal Print by Microsoft without third-party middleware.
  • You already standardize on Canon imageRUNNER and want one more device that drops into uniFLOW Online for fleet management.
Works fine

You'll be happy if...

  • You print 3,000-5,000 pages a month — the 6855i handles it easily, you'll just amortize a 55 ppm A3 over more time per page.
  • You don't need 70 ppm — the 6855i sits below the 6860i and 6870i; pick by monthly volume, not by spec sheet.
  • You're replacing a Canon iR-ADV 4500 series — the 10.1-inch flat-panel touchscreen and uniFLOW workflow translate directly.
  • You want finishing — staple, hole-punch, saddle-stitch are available with the Staple Finisher-AB2 or Booklet Finisher-A1; the standard model has 200-sheet output, max 3,450 sheets with full finishing.
Look elsewhere

Skip this if...

  • You print under 3,000 pages a month — you're paying for an A3 enterprise MFP and using 10% of it. Get the iR-ADV DX 617iF instead.
  • You need color — this is mono only. Look at the iR-ADV DX C5800 series for color A3.
  • You don't have floor space — this is a 24.4 x 28.5 x 36.9-inch unit weighing 200 lb basic configuration. Fully configured with finishing it spans 73.5 inches wide.
  • You need 13x19 — this engine maxes out at 12x18; for SRA3 / 13x19 step up to the 8700 series.
  • You don't have an authorized Canon dealer — GPR-63 toner and managed service are easier through contract channels.
Full specifications

Every spec, no guessing

The Canon imageRUNNER ADVANCE DX 6855i is the entry-level model in the current iR-ADV DX 6800 series, an A3 monochrome floor MFP for workgroups of 20-60 people that need real tabloid-size mono with current-gen hardware (256 GB SSD, 5 GB RAM, Trellix runtime intrusion detection). It prints and copies at 55 ppm letter, 36 ppm letter-R, 32 ppm legal, 29 ppm at 11x17, with first copy out in 2.9 seconds. Standard paper capacity is 1,200 sheets across dual 550-sheet cassettes and a 100-sheet stack bypass — expandable to 6,350 sheets with optional cassette feeding units, the 2,450-sheet HCFU-C1, and the 2,700-sheet Paper Deck Unit-F1. The 200-sheet single-pass DPF runs 270 ipm in duplex. The 10.1-inch flat-panel touchscreen runs uniFLOW Online, hot folders, and scan-to-everything (SMB, FTP, WebDAV, email, IFAX, Office Open XML). Connectivity is Gigabit Ethernet plus Wi-Fi standard, with native Cloud Connector for Google Drive, Box, Dropbox, OneDrive, and Universal Print by Microsoft. Security stack includes Trellix Embedded Control, FIPS 140-3 SSD encryption, and TPM. The thing buyers regret: scaling up too far. If your monthly volume is under 3,000 pages, this is overbuilt. The other thing to know: it sits below the 6860i (60 ppm) and 6870i (70 ppm) — pick by monthly volume, not by ppm bragging rights. Toner is GPR-63 Black.
