Epson WorkForce Enterprise AM-C400 ink cartridge, yellow

Yellow is the third base colour of colour printing. Mixed with cyan it produces greens; mixed with magenta, reds and oranges. Pure yellow rarely appears on a page, but it is present in almost every warm tone: foliage, sunsets, skin and spreadsheet highlights. When yellow runs out, colours turn cold and greens turn bluish.

The supplier provides no list of compatible printers for this cartridge, but it does give the product name WorkForce Enterprise AM-C400. That lets you match the cartridge to a printer whose documentation names AM-C400 consumables. The AM-C4000 and WF-C21000 cartridges of the same series are separate products, so check the exact name, not just the series.

The manufacturer is Epson, so this is an original consumable. The cartridge holds yellow only: cyan and magenta with the same product name are separate cartridges. You replace just the colour that has run out and do not throw away ink still left in the others. Over time that makes the cost of colour printing easier to keep under control.

The supplier's data has no page yield, so it is not possible to say how many pages one yellow cartridge prints. Consumption depends largely on content: green charts, maps and warm-toned photos use far more yellow than text documents. Keep an eye on the printer's ink level and use it to decide when to have a spare ready.

It is meant for owners of an Epson WorkForce Enterprise printer that uses the AM-C400 yellow cartridge. It suits those who prefer the manufacturer's original ink and want to replace each colour separately. If your printer is called AM-C4000 or WF-C21000, look for the cartridge marked for that model instead.
