Frequently Asked Questions

Why does this magenta cost more than the cyan and the yellow?

Straight answer: because that is where the three listings are priced. The GPR-31M is $133.64 against $116.76 for the yellow and $85.81 for the cyan, and all three carry the identical 27,000-page rating — there is no extra yield hiding in the higher price, and we will not pretend there is. What softens the arithmetic is the family's set pricing: bought as part of the 3-color set, the per-cartridge cost drops well below this single's price.

What does magenta actually carry in a color copy?

The warm half of everything. Magenta plus yellow builds every red and orange; magenta plus cyan builds purples and blues; on its own it carries pinks and, critically, a large share of human skin tones. That is why a weakening GPR-31M shows up first in faces — they drift pale, then slightly green — and in brand reds that stop looking like the brand.

What is the per-page cost of the magenta component?

Roughly 0.49 cents at standard coverage — $133.64 over a 27,000-page rating, and the highest per-page figure among the three GPR-31 colors. Treat it as a planning number: photo-heavy and marketing work with dense warm coverage spends magenta noticeably faster than the 5% coverage basis the rating assumes, while office documents with a red logo barely sip it.

How do we tell a dying magenta from a machine problem?

Print the color test page and isolate the magenta block. If the block itself is streaked, banded or uneven while cyan and yellow blocks print clean, the cartridge is the culprit. If all three color blocks look ragged together, suspect the machine first. Two minutes of test page saves swapping a healthy cartridge — or blaming the machine for a spent one.

Can the magenta be changed on its own schedule?

Yes — the four GPR-31 cartridges are independent, and magenta often genuinely needs its own rhythm: on photo and marketing queues it can empty ahead of the cyan and yellow, while on chart-heavy work it outlasts them. The black, rated at 36,000 pages, runs longer than all three colors regardless.

What protection comes with this cartridge?
