What's inside every ProColor cartridge

Chips, parts, yield and safety: how each part of a ProColor cartridge compares with industry standards.

Chips that talk to your printer

Smart chips

Chips that talk to your printer

Every ProColor cartridge carries a replacement chip that reports the cartridge model and toner level to your printer, so it is recognised on first install and page counts stay accurate.

  • Programmed for each printer model and its firmware
  • Accurate toner-level and page-count reporting
  • Every chip checked in a printer before packing
Industry standard: Chips should be recognised without error messages and keep working after firmware updates. ProColor matches each chip to its exact cartridge model.
Drum, rollers and blades built for clean prints

Core parts

Drum, rollers and blades built for clean prints

Print quality depends on the parts inside the shell. ProColor cartridges use a new OPC drum, a magnetic developer roller and precision wiper and doctor blades, fitted into a sturdy housing.

  • New OPC drum for sharp text and even greys
  • Magnetic developer roller for consistent toner flow
  • Precision blades that prevent streaks and leaks
  • Toner matched to each printer model
Industry standard: Good compatible cartridges use new drums and blades rather than worn originals, giving output close to OEM in density and sharpness.
Yield measured the standard way

Page yield

Yield measured the standard way

The page count printed on each ProColor box is based on the ISO method used by printer manufacturers, so you can compare costs per page fairly.

  • Rated at 5% page coverage, like the OEM rating
  • Toner fill matched to the rated yield
  • Sample cartridges print-tested from each batch
Industry standard: ISO/IEC 19752 (mono) and ISO/IEC 19798 (colour) define how laser cartridge yield is measured.
Safe for your office and the environment

Safety

Safe for your office and the environment

ProColor cartridges are sealed to stop spills, and the parts and toner we source are chosen to meet international safety rules for materials and handling.

  • Sealed shell and pull-tab to prevent toner leaks
  • Toner with a published safety data sheet (SDS)
  • Materials chosen for low hazardous-substance content
Industry standard: Common industry references include RoHS and REACH for materials, ISO 9001 for quality management and ISO 14001 for environmental management.
