Accounts departments, law firms, hospital records offices, and insurance agencies choose the 4003 and 4103 printers because they handle heavy daily volumes without fuss, often thousands of pages a week across shared departments and branch offices. The HP 151A Black Toner Cartridge keeps that output steady through month-end reconciliations, bulk KRA returns, and patient discharge summaries. The common problem is cost creep, when cheap cartridges get rejected by the printer or fail halfway through a print run. The HP 151A Black Toner Cartridge avoids both, working with the printer's security checks and printing at roughly KSh 6.20 per page with no separate drum to buy.

Unlike other electronics retailers in Kenya that sell grey-market or refilled stock, Mascom International sources sealed HP cartridges with intact security labels. At Mascom International, we're seeing more businesses move to the 4003 series as older M404 printers retire. Procurement officers also value its fixed yield when justifying orders to finance. Users consistently report that the HP 151A Black Toner Cartridge reaches its rated yield with sharp text to the last page. Walk in to confirm your printer model, or order with pay-on-arrival delivery to all 47 Kenyan counties.

It fits the LaserJet Pro 4003dn, 4003dw, and 4003n, and the LaserJet Pro MFP 4103dw, 4103fdn, and 4103fdw. HP+ versions ending in e, such as the 4003dwe and 4103fdwe, take the same cartridge. It will not fit the older M404 or M428, which use the 58A and 59A families. Check the model name on the printer's front panel. Send a photo on WhatsApp and our team confirms the fit before you pay.

HP rates the cartridge at about 3,050 pages under ISO/IEC 19752, which assumes about 5% toner coverage per page. Typed letters, invoices, and statements come close to that figure. Pages with tables, logos, or scanned images use more toner and lower the count. An accounts office printing 150 pages a day, five days a week, would finish one cartridge in about four weeks. A smaller practice printing 50 pages daily would get around three months from each cartridge.

About KSh 6.20 per page, based on KSh 18,900 divided by 3,050 pages. Because the 151A includes the imaging drum inside the cartridge, there is no separate drum cost to add. An office printing 3,000 pages a month spends close to KSh 18,600 on toner, which makes budgeting simple. Departments printing far more may consider the high-yield 151X, which spreads cost over more pages per cartridge and cuts the number of changes each quarter.

The 151A is the standard cartridge at about 3,050 pages, while the 151X is the high-yield version rated at roughly 9,700 pages.Both fit the same printers. The 151A suits offices printing up to about 3,000 pages monthly, with a lower upfront cost. The 151X suits busy departments that want fewer changes. Ask on WhatsApp about 151X availability and pricing.

It may. HP lists the LaserJet Pro 4003 and 4103 as dynamic security enabled printers, meaning firmware updates can block cartridges that use cloned or non-HP chips. HP+ models ending in e require original HP supplies by design. The 151A carries HP's own chip and anti-fraud technology, so the printer recognises it immediately. A cheaper cartridge that stops working after an update costs far more in downtime than the price difference you saved.

Check the colour-shifting security label on the box, then scan its QR code or enter the serial number on HP's anti-counterfeit site. The box should be factory sealed with no cut tape, and the cartridge sealed inside its protective bag. Once installed, the printer's supplies status page lists it as an original HP cartridge. Mascom International sells only sealed stock, and you can inspect every seal at our Kimathi Street counter before paying a shilling.

Keep spares sealed in their bags and boxes, lying flat, away from direct sun. HP rates storage from -20°C to 40°C and 10% to 90% humidity, which covers most offices from Nairobi to Mombasa. Operating conditions top out at 35°C with 20% to 80% humidity. In humid coastal towns such as Mombasa and Malindi, avoid storing cartridges near air-conditioner drip lines or open windows. Rock a new cartridge gently side to side before installing to spread the toner.

Any office running a LaserJet Pro 4003 or MFP 4103 that prints mostly black text in steady volumes. That includes CPAs preparing KRA submissions, advocates in Upper Hill chambers filing at Milimani Law Courts, hospital records teams at facilities like Nairobi Hospital or Aga Khan, and insurance agencies issuing policy documents. It also suits procurement officers who need a known yield for budgeting and audit trails. For home use, a smaller printer with cheaper supplies makes more sense.

Installation takes under two minutes and needs no technician or tools. Open the front door, pull the empty cartridge out by its handle, and remove the new one from its bag. Pull away the shipping seal and tape, rock the cartridge gently, then slide it in until it seats firmly and close the door. The printer reads the chip and shows the new toner level within seconds, ready for your next batch of statements or invoices.

Each cartridge is backed by the 6-month warranty above, with claims coordinated at our Nairobi CBD service desk.
