Canon Printer Not Recognizing Ink Cartridge

Common safe checks when a Canon printer does not recognize a new ink cartridge.

The short answer

Start with the exact Canon model, displayed code and cartridge number. An installation issue needs different checks from a low-ink or service warning. Use the model’s cartridge instructions before reseating anything; the TS7400 manual below illustrates why the latch and protective tape matter.

Before you start

  • Record the exact model, code, cartridge number and color.
  • Find that model’s cartridge-installation instructions before opening the cover.

What could be causing it?

Part number does not match
Compare the complete cartridge number with the model’s supplies list.
Installation is incomplete
The protective tape and locking mechanism must be handled as the model’s manual shows.

Read the wording before reseating anything

“Not recognized,” “not installed” and “low ink” describe different situations. Write down the code and the cartridge number before you touch the printer.

A newly purchased cartridge can still be the wrong regional variant. Compare its full number and color with the exact model’s manual.

Work through these checks

  1. Follow the manual’s cartridge-replacement access steps and wait for any moving carriage to stop.
  2. Check the part number and color position. Remove only the protective tape or packaging identified in the installation instructions.
  3. Seat the cartridge once using the documented latch. Do not scrape contacts, force the carriage or use solvents.
  4. Close the covers and allow the printer to check the cartridge. Record the message that remains.

What the result tells you

If the number is wrong, use the supplier’s return process. If the correct new cartridge is still rejected, send the code and model to Canon or the supplier.

B200 and absorber codes are separate service topics. Do not apply a cartridge-recognition sequence to an unrelated service error.

Worth avoiding

  • Do not scrape contacts aggressively.
  • Do not use firmware-bypass claims.
