Epson SJIC48P-M Magenta Ink Cartridge — 480 ml for ColorWorks CW-C8000e
Genuine Epson480 ml · MagentaUltraChrome DL pigmentColorWorks CW-C8000e
The Epson SJIC48P-M (T55P3) (C13T55P340) is a genuine Epson magenta ink cartridge — 480 ml of UltraChrome DL pigment ink — for the ColorWorks CW-C8000e colour label printer (BK and MK versions). It is for businesses printing colour product, compliance and brand labels on demand in-house.
The CW-C8000e runs four ink cartridges — black (BK or matte black MK, depending on the printer version), cyan, magenta and yellow — and each is replaced on its own, so you only buy the colour that has run out. Epson does not publish a label or page yield for this cartridge; consumption depends on label size, ink coverage and print mode.
Before you order: Cyan, magenta and yellow fit both the CW-C8000e (BK) and the CW-C8000e (MK). Only the black differs between the two versions — C13T55P140 for BK, C13T55P540 for MK.
What's in the Box
- 1 x Epson SJIC48P-M (T55P3) magenta ink cartridge (480 ml)
- Sealed Epson original packaging, part number C13T55P340
- Printer, other colours and maintenance parts not included
What It Means in Practice
- Replace only this colour when the printer reports it empty — the other cartridges keep running.
- Colour label designs drain cyan, magenta and yellow unevenly; brand colours and backgrounds decide which one you reorder most.
- Keep one spare of your most-used colour on site: a label printer waiting for a single cartridge stops the line.
- Keep the cartridge sealed in its packaging until you install it.
What Will Not Work
- Other ColorWorks models (CW-C4000e, CW-C6000 / C6500 series, C7500 series) — they use different ink cartridges.
- Epson office, photo and large-format printers — SJIC48P cartridges are for the CW-C8000e only.
- Black printing — this is the magenta cartridge; black is a separate cartridge (BK C13T55P140 or MK C13T55P540).
- The SJMB7500 maintenance box (C33S020596) — a separate consumable, not included.

Singular Expert Insight · Buyer's Guide
On a colour label printer the cartridge that empties first is rarely black — brand colours and backgrounds drain cyan, magenta or yellow unevenly, so watch which colour your designs use most and keep one spare of it. The full range of genuine cartridges is in
original inks, and the printers themselves in
label printers.
✓ Buy it if you run a ColorWorks CW-C8000e (BK or MK version) and the magenta is low.
✕ Skip it if you have a different ColorWorks model or an office inkjet — the cartridge will not fit.
→ Also consider the matching cyan (C13T55P240) and yellow (C13T55P440) cartridges, and the SJMB7500 maintenance box.
Not sure it fits? Send us your printer model (it is on the label at the back or in the printer menu) and we will confirm the right ink cartridge before you order.
