Epson WorkForce Enterprise AM-C400 ink cartridge, magenta

Magenta is one of the three colours that make up colour printing. With yellow it gives red and orange, with cyan blue and violet. Red charts, pink highlights, red logos and warm portraits all need this ink. When magenta runs low, reds turn yellowish and blues turn a cold green, and brand colours are the first to suffer.

In the Epson WorkForce Enterprise series the supplier carries both AM-C400 and AM-C4000 cartridges, and their names differ by just one digit. This cartridge's product name is WorkForce Enterprise AM-C400. Since there is no separate compatibility list, compare your printer's model label or the cartridge named in its manual with this name before installing.

The supplier lists Epson as the manufacturer, so this is an original consumable. The manufacturer's ink and cartridge are designed for printers of the same brand, which keeps colours predictable and lets the printer recognise the cartridge as intended. When an office prints material that goes to clients, stable colour often matters more than debating where a consumable came from.

The page yield field in the supplier's data is empty, so no specific number of pages can be promised. A practical approach is to watch the printer's ink level and note how long one magenta cartridge lasts at your usual workload. Those notes make it easy to decide when to get a spare.

It suits users of a WorkForce Enterprise printer that takes the AM-C400 magenta cartridge and who want to run on original Epson ink. Each colour sits in its own cartridge, so magenta is replaced exactly when it runs out while cyan and yellow stay in the printer.
