Marketing teams, architects, teachers and church administrators lean on cyan more than they realise. It forms the blues in company logos, the greens in pie charts and the sky in every printed photo. When cyan runs dry, an OfficeJet Pro stops printing entirely, even for plain black letters, because the printer needs all four slots filled. The HP 938 Cyan Ink Cartridge solves that stall with a sealed original that the printer accepts first time. At roughly KSh 5.63 per colour page, the HP 938 Cyan Ink Cartridge keeps presentation budgets easy to plan.

Where most Nairobi electronics shops sell loose cartridges with unclear origins, Mascom International lists the exact pack date so you know what you are buying. At Mascom International, we're seeing architecture firms in Kilimani and Lavington use wide-format OfficeJet Pro 9730 printers for A3 site plans, and those drawings drain cyan fast. Buyers throughout Kenya tell us that colour matches stay consistent between originals, which matters when a client compares two printed proofs. Visit our Kimathi Street counter, or order by phone with pay-on-arrival delivery to all 47 counties.

The OfficeJet Pro 9100 and 9700 series will not print anything with an empty or missing colour cartridge, including black-only documents. HP designs these printers to protect the printhead, which can be damaged if a slot runs dry and air enters the ink channel. So a single empty cyan can halt invoices, letters and reports at the same time. Keeping one spare HP 938 cyan on the shelf avoids that sudden stop during a busy week.

HP rates the cartridge at about 800 A4 pages under the ISO colour test, which assumes around 5% coverage per colour. An office printing 25 colour pages a day will usually get about six weeks from one cartridge. Pages full of blue banners, maps or photos use far more ink, so those jobs can halve the figure. The printer's ink gauge and the HP phone app both show the remaining level, so reordering is easy to time.

It fits the HP OfficeJet Pro 9110, 9120, 9130, 9720 and 9730 series. That includes the b and e versions such as the 9110b, 9120b, 9125e, 9130b and 9135e. The 9720 and 9730 are wide-format models that handle A3 paper, popular with engineers and design studios. If you bought your printer in the United States, check the label, because American units use the 936 cartridge number instead.

Yes. Of our current 938 stock, this cyan carries the latest pack date, giving well over a year before HP's printed window closes. HP's own warranty runs until the ink is used up or that date is reached, whichever comes first. That long runway makes the cartridge a safe choice for buying a spare now. Keep it sealed, stored between 0 and 40°C, and away from windows that catch the afternoon sun.

Original HP cyan is calibrated to work with the matching HP magenta and yellow, so the printer's colour profiles produce the blues and greens they were designed for. Refilled or third-party cyan often shifts logos toward purple or dull teal. For a real estate brochure, a school prospectus or a pitch deck printed for a client in Westlands, that colour drift looks careless. Use genuine cartridges in all four slots for the most predictable brand colours.

Buying the three colours together does not change the unit price, which stays at KSh 4,500 each, but it saves repeat trips and delivery fees. A complete black, cyan, magenta and yellow set costs KSh 20,000 at Mascom International. Many offices replace colours only as each empties, since usage differs by document type. Blue-heavy offices, such as those printing maps or corporate templates, often find cyan runs out first and keep two spares.

Yes, and it takes about a minute. With the printer on, open the ink access door and wait for the carriage to stop moving. Press the front of the old cyan cartridge to release it and lift it out. Remove the new cartridge from its packaging, avoid touching the copper contacts, and push it into the slot marked cyan until it clicks. Close the door and the printer will run a quick check before printing.

First, reseat it firmly and confirm it sits in the cyan slot, since each slot is colour-coded. Next, wipe the copper contacts gently with a dry, lint-free cloth and try again. If the message persists, update the printer firmware and restart. A genuine sealed cartridge from Mascom International that still fails is covered, so bring it to our Kimathi Street desk or WhatsApp us a photo of the error for a replacement.

Sealed cartridges handle most Kenyan conditions well. HP rates storage from 0 to 40°C and humidity from 5 to 80%, which covers Nairobi, Kisumu and most of the coast. The main risks are parked cars and sunny shelves, where temperatures can pass 40°C and thicken the ink. Offices in Mombasa and Malindi should store spares in a closed cupboard rather than near windows. Install within the pack date for the most consistent output.
