Frequently Asked Questions

Why do faces in our copies look sunburned and the reds turn orange?

That is the classic signature of a fading magenta. Reds are built mostly from magenta plus yellow, and skin tones lean on magenta more than any other colour — so when the GPR-23M runs down, reds slide toward orange and faces pick up a flushed, sunburned look while the rest of the page can seem almost normal. A solid red test block that prints unevenly confirms it.

What is magenta responsible for in production colour work?

Magenta carries reds, pinks and purples, and it is the colour that decides how warm a page feels. On copied material people actually look at — handouts with photos, charts with red highlights, anything carrying a company logo in red — the GPR-23M is usually the cartridge that makes the difference between output that looks professional and output that looks off.

How much printing does the $57.70 buy?

The GPR-23M is rated at up to 14,000 pages, which prices the magenta share of a page at roughly 0.41 cents at the standard 5% coverage the rating assumes. Red-heavy work — sale flyers, warning labels, branded material — covers more magenta per page and will shorten real-world life, so plan from your own output mix.

Will a fresh magenta keep our logo red the same red across a long run?

A healthy cartridge holds its density evenly from the first page of its life to the last, which is what keeps a brand red consistent through a long copying run. Colour drift partway through a job is normally one cartridge fading — and if it is the magenta, replacing it restores the balance without touching the other three.

Do we have to replace the other colours at the same time?

No. Each GPR-23 cartridge is a separate unit on its own schedule: the colours are each rated at 14,000 pages and the black at 26,000, so they finish at different times. Change the GPR-23M on its own, and only look at a colour set when two or three colours are running low together.

What cover comes with this cartridge?

Our 1-year warranty and 1-year free returns, the same as every compatible cartridge we sell. If a GPR-23M streaks, leaks or gives up far short of its rating, contact support Monday to Friday, 9 AM to 5 PM CST and we will replace or refund it under the warranty.
