Yellow rarely prints alone, yet almost every colour page needs it. It combines with cyan to make greens and with magenta to make oranges, reds and warm skin tones. When yellow runs dry, the whole colour job stops, even with full cyan and magenta. The HP 963 Yellow Ink Cartridge suits schools printing maps and charts, agricultural advisers producing farmer leaflets in Nakuru and Eldoret, and offices printing safety signage. Replacing yellow alone costs far less than a full set, and the HP 963 Yellow Ink Cartridge restores full colour immediately.

Unlike other electronics retailers in Kenya that sell cartridges without showing dates, Mascom International displays the printed HP date on every carton. This stock runs to January 2028, giving buyers HP warranty cover alongside our own shop warranty. At about KSh 6.71 per page, the standard yellow keeps upfront spending low for moderate colour users. Buyers throughout Kenya tell us they value the long date on this batch. Nairobi and its environs receive same-day delivery, and pay-on-arrival service reaches all 47 counties. Walk-in buyers pay by M-Pesa and collect in minutes.

It is the HP end-of-warranty date printed on the cartridge. HP's own cartridge warranty covers this unit until January 2028, over a year from now. That gives you two layers of protection: HP's cover until that date, and Mascom International's 6-month warranty from the day you buy. The date is not an ink expiry, but a long date does indicate recent stock. You can read the printed date on the carton at our counter before paying anything. Delivery customers see the same date at the door before handing over payment.

Green on an inkjet printer is made by mixing cyan and yellow. When yellow runs short, only cyan lands on the page, so grass, leaves, maps and green logos shift toward blue. Oranges turn pinkish for the same reason, because magenta prints without enough yellow. Check the ink level screen on the control panel first. If yellow shows low, replace it. If the level looks fine, run one printhead cleaning cycle and print a quality report. The yellow bar on that report shows immediately whether nozzles are firing properly.

Less than most people expect, but on almost every colour page. A business letter with a coloured logo uses a small amount. A school map, farm leaflet or product brochure with greens and oranges uses much more. HP rates the cartridge at about 700 pages on a standard office test set printed on an OfficeJet Pro 9020. Many offices find yellow lasts slightly longer than cyan or magenta, though photo-heavy work with warm tones changes that balance. Checking the printer's usage report after two months shows your real yellow consumption.

Yes, because the printer needs all four cartridges installed and working to print. OfficeJet Pro 9010 and 9020 models protect the printhead by stopping when a colour cartridge is empty. Even an office printing mostly black invoices and letters must keep a working yellow in place. The good news is that light colour users replace yellow rarely. At KSh 4,700, the standard size is the sensible choice for offices where colour appears mainly in logos and letterheads. Keeping one sealed spare avoids a stopped printer at month-end.

It depends on termly colour volume. This standard cartridge costs KSh 4,700 for about 700 pages, near KSh 6.71 per page. The HP 963XL yellow costs KSh 6,500 for about 1,600 pages, near KSh 4.06 per page. A school printing 400 colour pages a term suits the standard size. Schools at the scale of a large secondary school, printing report forms, maps and science charts for over 1,000 learners, save money with the XL over a full year. Bursars can compare both options using last year's printing records.

Yellow ink is light, so it shows best on bright white paper. On cream, recycled or coloured paper, yellow areas look duller, and greens can drift toward olive. For flyers and school handouts, standard white 80gsm office paper gives the cleanest result. If you must use coloured paper, print a test page first and adjust colours in your document before running the full job. A single test sheet costs far less than a wasted run of fifty flyers. Black text remains crisp on any light-coloured paper stock.

Yes. Each cartridge works independently, and the printer reports each level separately. A new yellow sits beside partly used cyan and magenta with no calibration needed. Colour balance stays accurate because all HP 963 inks share one formula family. The printer may run a short alignment after installation, which takes under a minute. Mixing a new yellow with an XL cyan or XL magenta also works, so you can size each colour to match your actual usage. There is no requirement to replace all colours together.
