Real estate agencies, church offices, private schools, and small design studios chose the M476 because one machine prints, scans, copies, and faxes in colour. Yet most of their pages are still black text: tenancy agreements, sermon notes, invoices, and report forms. That makes black the cartridge they replace most often. A failing refill in the black slot leaves streaks across every document, including the colour ones. The HP 312A Black Toner Cartridge restores sharp text and deep black in photos and logos. At KSh 19,000 for 2,400 pages, each page costs about KSh 7.92.

Unlike other electronics retailers in Kenya that repack refilled 312A shells as originals, Mascom International sells only sealed HP boxes with the security label intact. At Mascom International, we're seeing more M476 owners replace black alone rather than buying all four colours at once. Real estate agents working Karen, Runda, and Kileleshwa report that the HP 312A Black Toner Cartridge keeps listing flyers and lease documents crisp. Busier offices can compare the 312X, rated at 4,400 pages. Walk in to confirm your model before buying the HP 312A Black Toner Cartridge, or order with pay-on-arrival delivery to all 47 counties.

It fits three HP models: the Color LaserJet Pro MFP M476dn, M476dw, and M476nw. The model name appears on the front panel and on the configuration report. It will not fit the M477, M479, or M454, which use the 410A and 415A cartridge families. A wrong code wastes KSh 19,000 and holds up your printing for days. Send a photo of your printer's label on WhatsApp and our team confirms compatibility before you pay.

No. The M476 uses four separate cartridges, and each one is replaced only when it runs low. The control panel shows the level of every cartridge individually. Offices printing mostly text find that black usually runs out well before the colours need attention. Buying only the HP 312A Black Toner Cartridge when prompted keeps spending tied to real use, instead of paying for four cartridges when only one is empty. The cyan CF381A, yellow CF382A, and magenta CF383A are each rated at about 2,700 pages.

HP rates the 312A black at about 2,400 pages under ISO/IEC 19798, the test used for colour laser cartridges. Typed agreements, invoices, and memos come close to that figure. Pages with bold black headers, photos, or dark backgrounds use more toner and cut the count. An estate agency printing 80 pages a day, six days a week, would finish one cartridge in about five weeks. A church office printing 30 pages daily could run close to three months.

Buy the 312A if you print fewer than 1,500 black pages a month or prefer smaller single purchases. The 312X, part number CF380X, is rated at about 4,400 pages, nearly double the 312A figure. It fits the same three M476 models. Offices printing contracts and statements daily usually lower their cost per page with the 312X. The colour cartridges come in one yield only, so black is the only slot with this choice. Ask us for current 312X pricing and we will compare per-page costs against your monthly black volume.

Black toner and drum together cost about KSh 7.92 per page, based on KSh 19,000 divided by 2,400 pages. Because the drum sits inside each cartridge, no separate imaging unit adds cost later. An office printing 1,200 black pages a month would use about six cartridges a year, spending roughly KSh 114,000. Colour pages add the cyan, magenta, and yellow costs on top. Tracking black and colour separately makes monthly print budgets far easier to approve.

On the M476, dark tones and shadows in photos draw heavily on black toner. A refill with uneven toner or a worn drum leaves grey streaks and patchy blacks, which drag down the whole image. Text on those flyers also loses its sharp edges. The HP 312A Black Toner Cartridge brings a fresh drum and factory toner made for this printer. Estate agencies see the difference quickly, because photos of kitchens, gardens, and facades depend on clean shadow detail. Sharper prints also mean fewer reprints before a client viewing.

Look for HP's security label on the box. It changes colour when tilted, and its serial or QR code can be verified on HP's anti-counterfeit site. The factory seal should be unbroken, and the cartridge should sit in a sealed protective bag. Refilled units often show scuffed plastic, toner dust, or a replaced chip. The M476 displays a used or non-HP supply message when it detects one. Mascom International lets you inspect every seal at our Kimathi Street counter before any money changes hands.

Anyone running an M476 who prints mostly black text with regular colour work. That includes estate agents preparing leases and listing flyers, church administrators printing bulletins, private school offices printing report forms, and small studios producing client proposals in Westlands and along Mombasa Road. The M476dn and M476dw print both sides automatically, saving paper on long documents. Offices printing more than 2,000 black pages monthly should compare the 312X first, because its cost per page usually lands lower.
