HP 504A Black Toner Cartridge, part number CE250A, is available at Mascom International for KSh 14,500, brand new and sealed in HP's original retail box. This genuine HP LaserJet cartridge carries a rated yield of about 5,000 pages under the ISO/IEC 19798 test, and it uses HP's ColorSphere toner. It fits the HP Color LaserJet CP3525 series and the CM3530 MFP series. You can collect the HP 504A Black Toner Cartridge from our shop at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, or order it for delivery anywhere in Kenya.
Built for office managers, accountants, lawyers and school bursars across Kenya, the HP 504A Black Toner Cartridge handles the text-heavy work that keeps a business running: invoices, KRA filings, tenancy agreements, payslips and exam papers. When a black cartridge runs dry in the middle of month-end, a whole office in Upper Hill stalls while someone hunts for stock. Keeping one sealed spare on the shelf removes that risk. Black also carries most of the load in a colour office, since nearly every page has text on it, so the HP 504A Black Toner Cartridge is usually the one an office replaces first.
Where most Nairobi electronics shops mix refilled or compatible toner in with the real thing, Mascom International sells only original HP cartridges, sealed and traceable. Customers across Nairobi tell us that switching back to genuine HP toner stopped the grey streaks and smudged edges they were getting from cheaper refills. Every HP 504A Black Toner Cartridge we sell carries a 6-month warranty against manufacturing defects. Walk in to check the box and security label yourself, or order on WhatsApp and pay on arrival, whether your printer sits in the city centre or upcountry.
Common Questions About the HP 504A Black Toner Cartridge
How much is the HP 504A Black Toner Cartridge in Kenya?
The HP 504A Black Toner Cartridge costs KSh 14,500 at Mascom International in Nairobi, sold as genuine HP stock in its original box. That price covers the CE250A cartridge, a 6-month warranty on manufacturing defects, and pay-on-arrival delivery to all 47 counties. Same-day delivery applies within Nairobi and its environs. The cyan and yellow 504A cartridges sell at the same KSh 14,500, so a matched set for your CP3525 is simple to budget for.
Should I buy the HP 504A Black Toner Cartridge or the HP 504X high-yield version?
The HP 504A Black Toner Cartridge is HP's standard-yield black for the CP3525 and CM3530, rated at about 5,000 pages, while the HP 504X, part number CE250X, is the high-yield black that prints considerably more pages per cartridge. Both fit the same printers and use the same ColorSphere toner. Pick the 504A when you print moderate volumes or want a lower upfront spend. An office printing thousands of black pages a month may find the 504X cheaper per page; ask us on WhatsApp whether we can source it.
Will the HP 504A Black Toner Cartridge fit my HP Color LaserJet CP3525dn?
Yes, the HP 504A Black Toner Cartridge fits the HP Color LaserJet CP3525dn and the rest of the CP3520 series, including the CP3525n and CP3525x, plus the CM3530 and CM3530fs MFP models. It will not fit the older CP3505 or the newer Color LaserJet Pro range, which use different cartridges. If you are unsure of your model, send a photo of the label on the printer to +254 708 852 521 and we will confirm the fit before you pay.
How many pages does the HP 504A Black Toner Cartridge print?
The HP 504A Black Toner Cartridge is rated by HP at about 5,000 pages, measured under the ISO/IEC 19798 standard. That test uses a standard set of mixed text and graphics pages, so a typical letter or invoice lands close to the rating. Pages crammed with bold tables, scanned documents or dark images use more toner and bring the count down. An office printing 100 black pages a day should get roughly 50 working days, about two and a half months, from one cartridge.
How does the HP 504A Black Toner Cartridge cope with KPLC power cuts and dust?
A KPLC power cut will not harm the HP 504A Black Toner Cartridge, because toner is a dry powder that does not dry out or clog like inkjet ink while the printer sits off. Dust is the bigger risk. Keep the spare sealed in its bag until install day, and close the printer's front door between swaps. Offices near busy roads or building sites should wipe the printer exterior weekly. Plug the printer into a surge protector so voltage spikes when power returns do not harm its electronics.
Who should buy the HP 504A Black Toner Cartridge and who should skip it?
Buy the HP 504A Black Toner Cartridge if you run an HP Color LaserJet CP3525 or CM3530 and want clean text with a warranty behind it. Accountants, law firms, schools and SACCO offices printing daily will get the most from it. Skip it if your printer is any other model, such as a newer Color LaserJet Pro, because it will not fit. Offices printing thousands of black pages every month should look at the 504X high-yield cartridge instead.
Is the HP 504A Black Toner Cartridge at Mascom International genuine HP?
Yes, every HP 504A Black Toner Cartridge at Mascom International is genuine HP stock, never refilled, remanufactured or compatible. Each box carries HP's security label, which you can check in store before you pay. Counterfeit HP toner circulates in Kenya, often sold as original at a small discount, and it can leak, streak or trigger cartridge errors. Buying from a walk-in shop on Kimathi Street gives you a receipt, a 6-month warranty and a real counter to return to if something goes wrong.
What does each page cost with the HP 504A Black Toner Cartridge?
Each page costs about KSh 2.90 in toner with the HP 504A Black Toner Cartridge, working from the KSh 14,500 price and HP's rated 5,000-page yield. A 20-page tender document comes to roughly KSh 58 in black toner, with paper and power extra. That figure holds only when the cartridge reaches its full rated yield, which genuine HP toner is designed to do. Refills that streak or fail early often cost more per good page once wasted sheets are counted.
Technical Specifications
Page Yield and Print Quality
- Rated yield of about 5,000 pages under ISO/IEC 19798, the industry test HP uses for colour laser cartridges — months of steady office printing.
- Yield is measured on mixed text and graphics pages, so heavy tables, logos and scanned documents will bring the real count lower.
- HP ColorSphere toner gives sharp, dark black text that stays readable when contracts and invoices are photocopied or scanned later.
- Even black fill across the page — useful for bold headings, tables and barcodes that must scan cleanly at a till or warehouse.
- Steady output from the first page to near the end, with the printer warning you on its panel before the toner runs out.
Printer Compatibility
- HP Color LaserJet CP3525n — a networked model in the CP3520 series that shares one cartridge set across the whole office.
- HP Color LaserJet CP3525dn — adds automatic two-sided printing, so this cartridge also feeds duplex jobs that cut paper use in half.
- HP Color LaserJet CP3525x — the expanded version with an extra paper tray and two-sided printing, taking the same CE250A cartridge.
- HP Color LaserJet CM3530 MFP and CM3530fs MFP — the multifunction models that also copy and scan, printing with this same toner.
- Not compatible with other HP Color LaserJet families or any inkjet; check the model label on your printer before ordering.
Cartridge Build and Technology
- Genuine HP original LaserJet print cartridge, made by HP for the CP3525 and CM3530 — not refilled, remanufactured or compatible.
- HP ColorSphere toner — HP's toner formula for its colour laser printers, designed to fuse evenly onto paper for crisp edges.
- Laser technology uses dry toner powder, so the cartridge does not dry out or clog during holidays or long periods of downtime.
- Part of a four-cartridge set: black, cyan, magenta and yellow each install in their own slot inside the printer.
- The printer reads the cartridge's status, so remaining black toner shows on the control panel and in the printer's web page.
Running Cost
- KSh 14,500 divided by 5,000 rated pages comes to about KSh 2.90 per page in black toner.
- A 10-page board report costs roughly KSh 29 in toner, and a 100-page tender file costs roughly KSh 290.
- One cartridge covers about 50 working days at 100 black pages a day, so a business can plan toner as a monthly cost.
- Paper, electricity and printer servicing are separate costs and are not included in the per-page figure above.
- The per-page figure assumes the full rated yield; pages with heavy black areas use more toner and raise the real cost.
Inclusions
- One HP 504A Black Toner Cartridge, part number CE250A, sealed in its protective bag.
- HP original retail box carrying HP's security label, which you can inspect at the counter before paying.
- A Mascom International receipt, which serves as your proof of purchase for any warranty claim.
- 6-month warranty on manufacturing defects, handled at our Nairobi CBD service desk.
- WhatsApp help with installation questions and with confirming the cartridge's install-by date before you buy.
