The Canon 071 Black Toner Cartridge is a genuine OEM (Original Equipment Manufacturer) product designed for use with specific Canon imageCLASS printers. It ensures crisp, sharp black text and professional-quality prints every time. Engineered with Canon’s proprietary toner technology, it provides consistent performance, minimizes smudging, and supports energy-efficient printing.

The cartridge is easy to install and replace, and it’s designed to work seamlessly with Canon’s all-in-one cartridges that combine toner, drum, and developer into a single unit — simplifying maintenance and reducing downtime.

• High-quality output with bold, dark blacks
• Consistent and reliable performance
• Eco-conscious – recyclable through Canon’s toner recycling program
• Genuine Canon cartridge – protects your printer warranty and prevents damage from counterfeit supplies
• All-in-One design (includes toner and drum in one unit for easy installation)

• Model/Part Number: W1580A. 

• Color: Black. 

• Print Technology: Laser.

• Approximate Page Yield: ~2,500 pages (based on ISO/IEC 5% coverage) for the original HP version. 

• Designed for use with the HP “LaserJet Tank” series printers (i.e., the printers using refillable tanks/toner system).

• Provides sharp black text and graphics, consistent quality, and reliability. 

• Designed with less plastic usage (for the newer “tank” reload kits) and to support eco-friendly recycling (via HP’s Planet Partners).

• The cartridge is meant for compatible HP LaserJet Tank printers. 

•  For example, listings mention compatibility with models such as: HP LaserJet Tank MFP 1602a, 1602w, 1604w, 2602dn, 2602sdn, 2602sdw, 2603dn, 2603sdn, 2603sdw, 2604dn, 2604sdn, 2604sdw, 2605dsw, 2606dc, 2606dn, 2606dw, 2606sdn, 2606sdw

• Note: There are also compatible / third-party versions of “158A” where yields or exact compatibility may differ. (Always check for genuine HP original if quality/reliability is important.)

Key Features of the 77A OPC Drum

1. Compatibility

   • Works with HP 77A / CF277A toner cartridges.

   • Compatible with many HP LaserJet printers (e.g., M305, M403, M429 series) as per some suppliers.

2. Photoconductive Coating / OPC Layer

   • The drum has a photosensitive organic (OPC) coating which is critical for laser printing: it holds an electrostatic image, attracts toner, and then transfers it to paper.

   • Many compatible drums (aftermarket / OEM) claim high-quality OPC finish for good image density and sharp print quality. 

3. Durability & Refill Support

   • Some OPC drums (especially aftermarket ones) are built to support multiple toner refilling cycles. For example, the OEM A&G 77A drum supports 2–3 refill cycles.

   • There are “green” or more environmentally-optimized versions too. 

4. High Page Yield / Long Life

   • While an OPC drum is not the same as a toner cartridge yield, a good-quality drum gives stable print quality over many pages. Aftermarket listings specifically mention “high page yield (up to OEM standards).” 

   • With a well-maintained drum, you can maximize toner refills, reducing cost per page.

5. Print Quality

   • Helps achieve crisp and consistent printing (sharp text, clean background) because the photoconductor layer is well-coated.

   • Good OPC drums minimize background noise (undesired toner spots) and ghosting.

6. Reliable Performance

   • Designed to be “reliable in heavy-duty / business printers” according to parts sellers.

   • Compatible drums often highlight “smooth installation & full compatibility.” 

7. Cost-Effective

   • Aftermarket / compatible OPC drums are usually much cheaper than OEM drum units. (E.g., A&G roles are priced very low.) 

   • By reusing a drum for multiple toner refills, total printing cost can be reduced.

8. Light Sensitivity

   • Like most OPC drums, they are sensitive to light. If exposed to bright light for long, the photoconductive layer can degrade (this is a generic OPC constraint). 

   • Care during handling is required (avoid fingerprints, scratches)

When selecting a compatible mag roller (developer roller) for series like HP 158A / 158X, here are the typical / desirable attributes:

• Correct compatibility: Ensure the part states compatibility with your exact printer model (for example the listing mentions HP LaserJet Tank MFP 1005, 1005w, 1020w, 2606dn, 2606sdw etc). 

• Proper sleeve/coating: The outer sleeve must have uniform coating, good conductivity, correct roughness, and good adhesion of toner. Mag roller suppliers highlight “uniformity of coating”, “rich conductivity”, “enough surface roughness” as key to print quality.

• Magnetic core strength / correct dimensions: The core and sleeve should be sized correctly so the roller fits perfectly in the cartridge, makes correct contact, and rotates smoothly.

• Good condition: If re-used or refilled, look for signs of wear: shiny/glistening/flattened surface, uneven wear, breaks in sleeve, visible damage. If the surface looks glossy or worn, it may not deliver toner evenly.

• Avoid incorrect / second-hand parts: The listing for the mag roller often says “No warranty, no replacement guarantee” (for very low-cost imports) — so quality varies. 

• Compatibility: Make sure the roller is specified for your cartridge model (e.g., 28A/26A/77A/287A). The listing above includes CF287A among compatible cartridges.

• Quality of coating: The outer sleeve must have uniform coating, the correct roughness, good conductivity, and should be wear‑resistant. As one source puts it:

  “Uniformity of Coating … Rich Conductivity of Coating … Enough Surface Roughness … Durable Materials of Coating … Precise Cylindricity”

• Magnetic core strength & mechanical fit: The magnetic core must be strong enough to hold and transport toner effectively. The shaft, bearings, and side‑tabs should fit precisely and smoothly.

• Condition of surface: If the surface appears shiny, worn out, or has uneven patches (toner missing, scarred surface), the roller’s performance is likely degraded.

• Longevity & consistent output: A good mag‑roller will maintain consistent toner distribution over many pages and avoid sudden drop in print density or quality.
