How to find your exact ink or toner number

Printer aisles are organized by brand families. Cartridges are not. “Envy,” “EcoTank,” and “LaserJet” are series names. The cartridge number belongs to a specific model, and sometimes to a regional or “e” variant of that model.

Find the full model, not the series

Check these spots in order. Write down every character, including letters after the digits.

1. Inside the cartridge door or toner door. Many inkjets print the model and the cartridge family on a sticker next to the stall.
2. The back or bottom regulatory plate. This is the most reliable full model (for example HP ENVY 6055e, Epson ET-2800, Brother HL-L2395DW).
3. The printer’s own menu under Settings, Printer info, or Supplies — lasers often list toner and drum part numbers here.

If a box or website only says the series, keep looking. Series pages often list several cartridge families.

Read the number on the cartridge you already have

Leave the old cartridge in the printer until you have the number. Pull it only far enough to see the label, or use the last box if you kept it.

Useful markings:

• A short number such as 67, 245, 63, 235, or TN-760.
• A suffix such as XL, XXL, HC, or High Yield.
• Color words or a small color square.
• For laser: TN (toner) and DR (drum) are different parts.

Photograph the label. Retail sites search that string more reliably than the marketing name on the front of the printer.

Before you pay

• Full model from the plate, not the brochure name.
• Cartridge or bottle number from the door or from the old supply.
• Standard vs XL chosen on purpose (same stall; XL holds more).
• Color count matches; for laser, toner vs drum confirmed.

If the printer shows “non-genuine” or “incompatible” after a swap, recheck the number against the door sticker before you assume the printer is broken.
