Two rectangular black ink cartridges side by side

True Color Toner CLI-42 Black Ink Cartridge 2 Pack

SKU CH-WCQ4-4TH15

Two black ink cartridges replace Canon CLI-42 for Pixma Pro-100 printers

  • Two-pack supplies spare black ink for high-volume printing
  • STMC and ISO manufacturing standards ensure consistent output quality
  • Direct fit for Canon Pixma Pro-100 eliminates installation issues
  • Aftermarket formulation matches original density and colour accuracy
  • Reputable compatible brand reduces per-page cost without quality loss

Replacement Black Cartridge for Pro-100

This two-pack supplies black ink cartridges built to fit the Canon Pixma Pro-100. They are intended for photographers and designers who need consistent monochrome output on a variety of media. The aftermarket units install directly into the printer without modification. Each cartridge is formulated to match the original CLI-42 specification.

Steady Output Over Long Print Runs

The cartridges are manufactured under STMC and ISO processes to maintain density and tone across extended jobs. Users report reliable page-to-page consistency without banding or density drift during sustained printing. The ink formulation resists settling, so the first page and the last page in a batch look the same. This stability suits studio workflows that run multiple prints in one session.

Alternative to OEM CLI-42 Singles

The pack replaces individual OEM black cartridges with a lower cost per unit while preserving print fidelity. The jump makes sense for studios that consume black ink quickly and want to reduce recurring supply expense. Buyers who need colour cartridges or who print only occasionally will not gain the same value from this black-only multipack.

Questions about this item

Does the CLI-42 cartridge run hot or draw extra power during long print sessions?

The cartridge is a passive ink supply with no electronics that generate heat or consume power; the printer itself manages all thermal and electrical load.

What must I already own for these two black cartridges to work?

You need a Canon Pixma Pro-100 printer that accepts CLI-42 cartridges; the pack contains only the ink tanks and no printhead or maintenance parts.

Will the CLI-42 black tanks work alongside the older colour cartridges I still have in my Pro-100?

Yes, each colour slot is independent, so a new CLI-42 black cartridge installs and prints normally beside any remaining original or compatible colour tanks.
