Event planners, church offices, salons, schools and small marketing agencies print more red and pink than almost anyone. Magenta builds the reds in sale posters, the warm tones in faces, and the purples in wedding programmes and graduation certificates. When magenta empties, the whole OfficeJet Pro stops, because these printers refuse every job until all four slots hold ink. The HP 938 Magenta Ink Cartridge fixes that with a sealed original the printer reads correctly on the first try. At about KSh 5.63 per colour page, the HP 938 Magenta Ink Cartridge keeps flyer runs affordable.

Unlike traditional electronics retailers in Kenya that stock whatever cartridges arrive, Mascom International prints the pack date in every listing so you can plan spares. Our team at Mascom International tracks colour cartridge demand, and magenta sells fastest in the weeks before school closing days and December events. Customers across Nairobi report cleaner skin tones in printed photos once they return to original magenta after refills. Order by WhatsApp from Nakuru, Eldoret or Kisii and pay on arrival, or walk in to our Kimathi Street store.

Magenta is the pink-red base colour in your printer's four-ink set. On its own it prints pinks and purples, and mixed with yellow it forms the reds on sale posters, road-safety signs and company logos. It also adds warmth to skin tones in photos and ID-style portraits. Because so many everyday colours contain some magenta, a flyer or certificate run can drain it faster than cyan or yellow, even when the design does not look pink.

Certificates, church programmes and event posters often carry red borders, maroon crests and full-colour photos. Each of those areas uses heavy magenta coverage, often well above the 5% HP assumes for its 800-page rating. A school printing 300 end-of-term certificates with red seals may empty one cartridge in a single run. For big seasonal jobs, buy two cartridges at KSh 4,500 each, so a second is ready when the first warning appears.

Look at the front or top panel of your printer for the model name. If it reads OfficeJet Pro 9110, 9120, 9130, 9720 or 9730, including any b or e suffix, the 938 magenta is correct. You can also open the ink door and read the number printed beside the slots. Still unsure? Send a clear photo to +254 708 852 521 on WhatsApp, and our team will confirm the match before you pay anything.

You have more than a year, as long as it stays sealed. HP's warranty on the cartridge runs until the ink is used up or the end-of-warranty date is reached, whichever comes first. Store it between 0 and 40°C and away from direct sunlight. Install it before November 2027 for the most reliable colour, and keep the oldest spare at the front of the cupboard so it gets used first.

Yes, if colour accuracy matters to your brand. Refilled magenta commonly prints reds that look orange or washed out, and uneven ink can band across large solid areas. That reprints the whole job and wastes paper worth more than the saving. Genuine HP 938 magenta is matched to HP's colour profiles, so a red logo printed today matches the one printed next month. For salons, agencies and real estate agents in Karen and Runda, that consistency protects brand image.

Yes. The HP OfficeJet Pro 9720 and 9730 wide-format printers use the same 938 cartridges as the smaller 9100 series. On those machines you can print A3 posters and borderless flyers, which use more magenta per page than A4 letters. Expect fewer than 800 pages when printing full A3 colour. Design studios and event companies in Westlands often keep a pair of magenta spares beside their 9730 for that reason.

A sealed genuine cartridge should never show a counterfeit message. If you see one, reseat the cartridge, clean the copper contacts with a dry cloth, and restart the printer. A used-cartridge alert can appear if a cartridge was previously installed elsewhere, which does not happen with our sealed stock. Should any Mascom International magenta still fail, WhatsApp us a photo of the screen or bring it to Kimathi Street for a replacement under the cover below.

Leave the printer plugged in and switched off with its own power button, not at the wall, so it can cap the printhead properly. Print one colour page each week to keep the nozzles moist. During long KPLC power cuts, the printer may run a cleaning cycle when power returns, using a little ink. Offices closed over school holidays should print a test page on return before starting large certificate or flyer runs.

Nairobi and its environs receive same-day delivery on orders confirmed during working hours. Mombasa, Kisumu, Nakuru, Eldoret and other major towns receive the cartridge the next business day. You pay only when it arrives, after checking the seal and pack date. For urgent jobs, you can also collect the cartridge in person from our Kimathi Street store between 9:00 AM and 7:00 PM, Monday to Saturday.

Each cartridge carries the HP and Mascom cover set out above, with claims coordinated from our Nairobi CBD desk. Buyers across Kenya rely on Mascom International for dated, sealed original ink and straight answers on every printer supply we sell.
