Toner cartridge G&G 13979 compatible with OKI, Black, yield 2,200 pages, 1 pc

G&G 13979 compatible black toner cartridge is manufactured as an economical replacement for OKI monochrome laser printers. Supplied as a single unit, this cartridge provides an estimated yield of approximately 2,200 pages in black under standard testing conditions and is intended for routine document and office printing where consistent black output is required.

Advantages

The cartridge offers predictable page yield and straightforward installation as a drop-in replacement for compatible OKI devices. It is designed to provide clear black text and graphics for everyday office documents while keeping running costs lower than many original-brand options. Packaged as one unit, it simplifies inventory management for users needing a single spare cartridge.

Suitable for

• General office document printing (letters, reports, invoices)
• Small business workgroups with monochrome printing needs
• Home offices that require economical black-only printing
• Print jobs with a focus on text and simple graphics

When it may not be suitable

This compatible cartridge is intended for monochrome printing; it is not suitable for colour prints or colour-capable printers. Users requiring very high-volume printing or extended heavy-duty duty cycles may find higher-capacity or original high-yield cartridges more appropriate.

How to use

Power off the printer or follow the manufacturer’s instructions for safe cartridge replacement. Open the printer access panel, remove the empty cartridge according to the printer manual, and unpack the G&G 13979 cartridge. Remove any protective seals or packaging material, align the cartridge with the guide rails, and slide it into the cartridge bay until it clicks into place. Close the access panel and run a test print or alignment procedure if recommended by the printer.

What to consider before purchase

• Confirm physical compatibility with your OKI printer model and review the printer manual for compatible cartridge types.
• Consider your average monthly print volume to determine whether a standard 2,200-page yield cartridge meets your needs.
• Check warranty and return policies for third-party cartridges in your region.

Usage recommendations

Store the cartridge in a cool, dry place away from direct sunlight. For consistent print quality, run occasional calibration or cleaning cycles as recommended by your printer manufacturer and replace the cartridge once print density or clarity declines.
