Canon PIXMA TR8620a vs Color imageCLASS LBP646Cdw: Which Workflow Fits?

The TR8620a is the better feature fit when you need copying, scanning, faxing, or its 20-sheet letter-size feeder. The LBP646Cdw is a print-only alternative with Canon 075 and 075H toner options. Canon's published information does not establish which printer costs less to run or produces better-looking output.

The buying question

Do you need scanning, copying, and faxing at the printer, or is a print-only workflow with Canon 075-series toner a better fit?

The TR8620a adds document capture and handling functions, while the LBP646Cdw is print-only and uses a different consumable system with stated toner page-yield options.

Quick verdict

When the recommendation changes
  • If scanning, copying, or faxing becomes necessary, the TR8620a's documented functions become more relevant.
  • If printing is the only task and your supply plan favors the 075/075H toner family, the LBP646Cdw becomes more relevant; the cited yield figures do not establish lower cost per page.

The differences that matter

Document Tasks And Handling

Canon PIXMA TR8620a

Canon lists print, copy, scan, and fax functions. Its ADF can copy or scan up to 20 letter-size pages in a batch.[1]

Canon Color imageCLASS LBP646Cdw

Canon lists the LBP646Cdw's function as Print.[2]

What this changes: Choose the TR8620a if you need those document tasks on the printer. The LBP646Cdw's listed function set is for printing, so it does not replace separate scanning, copying, or fax equipment.[1, 2]

Printing Supplies And Job Fit

Canon PIXMA TR8620a

The TR8620a uses a five-color individual ink system: PGI-280 pigment black and CLI-281 dye-based inks. Canon lists standard, XL, and XXL tank fill volumes for these inks.[1]

Canon Color imageCLASS LBP646Cdw

The LBP646Cdw uses Canon 075 or 075H CMYK toner. Canon lists up to 1,300 black/color pages for 075, and up to 3,500 black or 2,500 color pages for 075H.[2]

What this changes: The consumables are different families and their published measures are not directly comparable: the TR8620a page lists ink fill volumes, while Canon lists estimated page yields for the LBP646Cdw toner. Check which supplies you already stock and do not treat these figures as proof of a lower running cost.[1, 2]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare current displayed prices against the value of the TR8620a's document functions and your preferred supply workflow; the available comparison does not establish per-page cost or a price-history-based timing recommendation.

The available price evidence does not establish a purchase-timing conclusion.

Limitations

  • This comparison uses Canon's published specifications; no hands-on or side-by-side print test was performed.
  • Canon's toner page-yield estimates and the TR8620a's listed ink fill volumes are different measures and do not establish comparative running cost.
  • Print quality, real-world speed, and output for an individual job mix were not compared.

Questions shoppers ask

Can the LBP646Cdw scan or copy documents?

Canon lists its function as print. The TR8620a is the model in this pair whose Canon page lists copy and scan functions and a document feeder.

Can Canon's listed supply figures show which printer is cheaper to run?

No. The TR8620a specifications list ink fill volumes, while the LBP646Cdw page lists toner page-yield estimates. Those figures alone do not provide a shared cost-per-page comparison for your documents.

Methodology and sources

Compared the official U.S. model pages for documented document tasks, feeder handling, and the named ink or toner systems. Manufacturer yield estimates were kept separate from real-world performance and cost conclusions.
