Canon PIXMA TR7120 vs HP Envy 6155: ADF or Touchscreen?

For repeated multipage originals, the Canon is the documented fit: it has a 35-sheet plain-paper ADF, with a five-sheet capacity for legal originals. HP lists a flatbed scanner for the Envy 6155. If scanning is occasional and a larger color touchscreen matters more, the HP may fit better; neither choice is a tested performance winner.

The buying question

Should multipage originals and a documented feeder, or a larger color touchscreen, carry more weight in this printer choice?

Canon specifies a sheet feeder for multipage originals, while HP specifies a flatbed scanner and a larger color touchscreen; the better fit depends on which task matters more.

Quick verdict

When to skip: You require confirmed automatic two-sided scanning through an ADF; choose a model whose manufacturer explicitly documents that workflow.
When the recommendation changes
  • A confirmed need for automatic two-sided scanning would change the shortlist; the cited specifications do not establish that workflow for either printer.
  • A current offer and a realistic ink-cost comparison could change the value decision; prices were not assessed here.

The differences that matter

Multi Page Scan Copy Handling

Canon PIXMA TR7120 (7178C002)

Canon specifies a flatbed plus ADF; the feeder holds 35 sheets of plain paper or 5 legal-size sheets, and accepts legal-size originals.[1, 2]

HP Envy 6155 (C2WR7A#B1H)

HP specifies a flatbed scanner, with a maximum flatbed scan size of 8.5 × 11.7 inches.[3]

What this changes: The Canon's documented feeder is useful when several originals need to be scanned or copied without placing each page on the glass. The cited HP specification lists a flatbed scanner; it does not establish a feeder. These specifications do not establish automatic duplex scanning or comparative scan speed.[1, 3]

Printer Display And Local Controls

Canon PIXMA TR7120 (7178C002)

1.42-inch monochrome OLED display.[1, 2]

HP Envy 6155 (C2WR7A#B1H)

2.4-inch color capacitive touchscreen.[3]

What this changes: The HP offers a larger color touchscreen; the Canon has a smaller monochrome OLED. This is a display and interaction preference, not evidence that either printer is easier or faster to use.[1, 3]

Value and trade-offs

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

Current offers and price history were not assessed, so no relative-price or value judgment is supported. Compare live purchase terms and ink costs for the expected print volume.

Current offers and price history were not assessed; no timing recommendation is made.

Limitations

  • The cited specifications do not establish automatic two-sided scanning through the ADF on either model. HP's automatic two-sided specification is for printing.
  • No hands-on testing or comparative print, scan-speed, image-quality, reliability, or ease-of-use evaluation was performed.
  • Current prices and ink costs were not assessed.

Questions shoppers ask

How many pages can the Canon TR7120 feeder handle?

Canon specifies up to 35 sheets of plain paper or 5 legal-size sheets in the ADF. It lists legal-size originals for the feeder.

Does automatic two-sided printing mean the HP can scan both sides of an original automatically?

No such conclusion follows from the print specification. HP lists automatic duplex printing and a flatbed scanner; the cited specifications do not confirm automatic two-sided scanning through an ADF.

Methodology and sources

Compared the manufacturers' listed scanner types, Canon's stated ADF capacity and legal-size handling, and each printer's display specification. Recommendations describe feature fit; no print, scan-speed, image-quality, reliability, or usability winner is claimed.
