Keeps your dot matrix invoice and receipt paperwork sharp across Kenyan offices, priced at KSh 900 with countrywide pay-on-arrival delivery


Condition: New




Note: price and availability are subject to change without prior notice



Epson Ribbon LX-350 is now available at Mascom International for KSh 900, supplied as a genuine black fabric cassette rated for up to 4 million characters. This is the original Epson consumable for the LX-350 nine-pin dot matrix printer, and the same cassette also seats in the older LX-300+ and LX-300+II. Stock sits on the shelf at our Nairobi CBD store, Old Mutual Building, First Floor Room 4, Kimathi Street. Every Epson Ribbon LX-350 arrives brand new and sealed in its factory carton, with the part code printed where you can read it. Mascom International keeps the Epson Ribbon LX-350 in continuous supply because impact printers still run daily across Kenyan offices.

Accountants, hardware store owners, pharmacy operators, school bursars, and clearing agents working the Mombasa port corridor still depend on impact printing for carbon-copy invoices, delivery notes, and receipt books. Laser and inkjet machines cannot press ink through four carbon copies in one pass; a nine-pin print head can. The problem most Kenyan offices hit is a faded ribbon halfway through a busy month, which forces staff to reprint documents customers have already signed and stamped. The Epson Ribbon LX-350 removes that interruption. One cassette covers roughly 2,600 densely typed A4 invoices before print density drops far enough to warrant a change.

Unlike other electronics retailers in Kenya who stock only unbranded compatible refills, Mascom International sells the original Epson cassette with the Epson part code printed on the shell and the carton. Buyers throughout Kenya tell us imitation ribbons shed fibre onto the print wires, and a replacement print head costs several times the KSh 900 this cassette asks. At Mascom International, we're seeing SACCO offices and county revenue desks buy the Epson Ribbon LX-350 five and ten cassettes at a time to cover a full quarter. Walk into our Kimathi Street counter, or order the Epson Ribbon LX-350 for pay-on-arrival delivery anywhere in Kenya.

Common Questions About the Epson Ribbon LX-350

Is the Epson Ribbon LX-350 sold at Mascom International genuine?
Yes. Mascom International supplies the original Epson black fabric cassette, not an unbranded refill. The Epson part code is printed on the cassette shell and on the outer carton, so you can check it against your printer manual before installing. Genuine cassettes use fabric and ink Epson matched to the nine-pin print head. Imitation ribbons often use coarser cloth that sheds fibre onto the wires. Our counter staff will open the carton with you and point out the code.

How many invoices will one Epson Ribbon LX-350 print?
About 2,600 densely typed A4 invoices. Epson rates the cassette at 4 million characters in draft mode at 10 characters per inch. Short receipts and delivery notes carry fewer characters, so a busy hardware shop printing till slips often clears 5,000 documents. Bold and near-letter-quality printing use more strikes per character and cut that figure. At KSh 900, the running cost lands near KSh 0.34 per invoice. Most Nairobi offices change the cassette every four to six months.

Which printers does the Epson Ribbon LX-350 fit?
The Epson Ribbon LX-350 nine-pin dot matrix printer first, and also the older Epson LX-300+ and LX-300+II. Offices running a mix of those three machines can hold one spare part number instead of three. The cassette does not fit LQ-series 24-pin printers or the wider FX-880 family, which use different shell shapes. Fitting the wrong cassette risks bending print wires. Send your printer's model plate photo on WhatsApp and Mascom International will confirm the match before you pay.

Why buy the Epson Ribbon LX-350 instead of a cheaper compatible ribbon?
Print head protection. A nine-pin head is rated for 400 million strokes per wire, and coarse imitation fabric wears those wires faster than Epson's own weave. Replacing an LX-350 print head costs several times the KSh 900 this cassette asks. Users consistently report that cheap ribbons also fade unevenly, leaving the fourth carbon copy of a delivery note unreadable. Unlike other electronics retailers in Kenya who stock only generic refills, Mascom International keeps the original Epson consumable on the shelf.

How do I install the Epson Ribbon LX-350?
Switch the printer off, wait for the print head to cool, then lift the cover. Slide the ribbon guide between the print head and the front plate, and press the cassette down until it clicks into the carriage. Turn the tightening knob clockwise to take up slack. The whole change takes under a minute and needs no tools. Leaving slack in the fabric is the usual cause of a torn ribbon on the first page.

Will the Epson Ribbon LX-350 print carbon copies clearly?
Yes. The LX-350 is rated for one original plus four copies in a single pass, and this cassette carries enough ink saturation for the bottom copy to stay readable. That matters for delivery notes, waybills, and receipt books used by clearing agents in Mombasa and distributors along Kirinyaga Road. Bar codes in Code 39, Code 128, and EAN-13 also scan cleanly while the ribbon is fresh. A worn ribbon is the usual reason warehouse scanners start failing.

Does Mascom International sell the Epson Ribbon LX-350 in bulk?
Yes. SACCO offices, school bursars, and county revenue desks regularly buy five to twenty cassettes at once to cover a full term or financial quarter. Mascom International quotes bulk pricing from our Kimathi Street counter or over WhatsApp on +254 708 852 521, usually the same day. Bulk orders ship together under one pay-on-arrival delivery, which keeps transport cost per cassette low for buyers in Kisumu, Nakuru, and Eldoret. Sealed cartons store well on a dry shelf.

How quickly can I get the Epson Ribbon LX-350 outside Nairobi?
Same day within Nairobi and its environs, and 1 business day to every other major town, including Mombasa, Kisumu, Nakuru, Eldoret, Nyeri, Meru, and Garissa. Mandera, Wajir, Marsabit, Lamu, Tana River, and Turkana receive delivery within 2-3 business days. You pay only when the sealed carton reaches you. Order before 3:00 PM Monday through Saturday and Mascom International dispatches the same working day. A stopped invoice printer costs a business far more than any courier fee.

Technical Specifications

Ribbon Construction and Ink Formulation
  • Woven nylon fabric loop soaked in Epson black ink, chosen so fibres resist fraying against nine print wires.
  • Ink mix controls how much pigment transfers per strike, holding character darkness even from first page to last.
  • Sealed cassette shell keeps the fabric loop under tension, so it does not jump free during a print run.
  • Tightening knob moulded into the cassette body lets you take up slack without touching the inked fabric.
  • Black is the only colour Epson produces in this cassette, matching the LX-350 single-colour nine-pin head.
  • Cassette body clips into the carriage rather than screwing down, so nothing loosens under printing vibration.
Printer Compatibility and Model Coverage
  • Fits the Epson LX-350 nine-pin dot matrix printer, the model most Kenyan back offices still run for invoicing.
  • Also seats correctly in the older Epson LX-300+ and LX-300+II, so mixed printer fleets share one spare part.
  • Part code C13S015637 in the EMEA supply chain that serves Kenya; the Americas listing carries code S015631.
  • Does not fit LQ-series 24-pin machines or wide-carriage FX-880 printers, which take a different cassette shape.
  • Mascom International staff check the fit against your printer's model plate before you pay for the cassette.
Yield, Running Cost, and Document Output
  • Rated at 4 million characters in draft mode at 10 characters per inch, 14 dots per character.
  • Covers roughly 2,600 densely typed A4 invoices, or well past 5,000 short receipts and delivery notes.
  • Works out near KSh 0.34 per invoice, keeping ribbon cost a rounding error on any stationery budget.
  • Yield drops when you print bold, double-strike, or near-letter-quality text, since each character takes extra strikes.
  • Print density fades gradually rather than stopping dead, giving your team days of warning before replacement.
  • The LX-350 itself is rated for 20 million total printed lines, so ribbons outnumber printers many times over.
Installation and Cassette Handling
  • Cassette drops into the LX-350 carriage in under a minute, with no tools and no loose ink.
  • Switch the printer off and let the print head cool before lifting the cover, avoiding burnt fingers.
  • Slide the ribbon guide between the print head and the front plate, then press the cassette down.
  • Rotate the tightening knob clockwise to clear slack, otherwise the fabric catches and tears on the first pass.
  • Keep the spent cassette until the new one prints cleanly, in case the guide has seated wrong.
  • Handle the cassette by its plastic shell only; finger oil on the fabric shows up as pale patches.
Print Quality and Multi-Part Form Output
  • Supports the LX-350 rating of one original plus four carbon copies produced in a single printing pass.
  • Ink saturation is set so the fourth copy stays readable, which matters for waybills and signed delivery notes.
  • Bar code fonts including Code 39, Code 128, EAN-13, and UPC-A scan cleanly with a fresh ribbon.
  • Draft, Roman, Sans Serif, and OCR-B resident fonts print at consistent weight through most of the cassette life.
  • A worn ribbon is the most common cause of failed bar code scans on warehouse and dispatch paperwork.
  • Character output holds at 347 characters per second in high-speed draft without the fabric snagging or stretching.
Storage, Shelf Handling, and Working Conditions
  • Store sealed cassettes between 5 and 35 degrees Celsius, away from direct sun on window-side stockroom shelves.
  • Coastal humidity in Mombasa, Malindi, and Lamu softens exposed fabric, so keep spares inside the factory wrap.
  • Sealed cartons hold usable ink far longer than opened ones, which makes buying a term's supply sensible.
  • The LX-350 printer itself runs between 5 and 35 degrees Celsius at 10 to 80 percent relative humidity.
  • Dust is the second enemy: cover the printer overnight in Industrial Area and River Road workshop settings.
  • Keep cassettes flat rather than on edge, so the fabric loop does not settle unevenly inside the shell.
