Direct answer
For the Canon imageCLASS MF455dw, exact part compatibility, shipping seals, contacts, seating and firmware should be checked before replacement. First, record the exact supply part and message.
What this covers
- Canon imageCLASS MF455dw (5161C005)
- Canon printer; PIXMA/MegaTank/MAXIFY/imageCLASS ink/toner systems and maintenance paths differ.
- The specific fault this record addresses: does not recognize ink or toner
What it does not cover
- ×The same symptom on a different Canon product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The cartridge is not fully seated
What separates it Rejection immediately after installing, with no positive click when it went in.
How to confirm Remove and reinstall until it latches firmly. This is the most common cause and takes seconds.
- 2
Protective packaging was not fully removed
What separates it A new cartridge rejected on first installation.
How to confirm Tape, clips and covers over the chip contacts prevent the chip being read.
- 3
The chip contacts are dirty
What separates it Intermittent recognition, or a cartridge that works after being removed and refitted.
How to confirm Wipe the copper contacts on the cartridge and, carefully, in the carriage with a dry lint-free cloth.
- 4
The cartridge is the wrong regional or model variant
What separates it A cartridge that looks correct and fits but is rejected outright.
How to confirm Compare the exact part number against the printer's supported list. Regional variants of the same number exist and are not interchangeable.
- 5
A firmware update has blocked a third-party cartridge
What separates it A third-party cartridge that worked stops being recognised after a firmware update.
How to confirm This is a known and deliberate outcome of some firmware updates. It is worth understanding before assuming the cartridge failed.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- The exact part number on the cartridge, compared with the printer's supported list.
- Whether the cartridge is genuine, third-party or refilled.
- Whether a firmware update was installed recently.
- Whether the cartridge clicks positively into place.

Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- 5161C005. Canon printer; PIXMA/MegaTank/MAXIFY/imageCLASS ink/toner systems and maintenance paths differ.
- Type — MONOCHROME LASER all-in-one (toner)
- A black-and-white laser AIO (scan/copy/fax, duplex, wireless) — prints only in BLACK by design, for fast, low-cost text. Laser uses toner and does not clog from disuse.
- Toner & drum
- Faded print is low/unseated toner; streaks/repeating marks are toner or drum. No colour because it is a mono printer.
- Connectivity
- Wi-Fi/Ethernet/USB; 'offline' is usually a network/queue issue.
- Symptom boundary
- This record covers Canon imageCLASS MF455dw when it does not recognize ink or toner. A different symptom on the same hardware, or this symptom on a different Canon product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Do not touch the printhead nozzles or the electrical contacts with bare fingers, and never clean contacts with a wet or solvent-soaked cloth.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Canon publishes this as "Support Code 1430 (Ink Cartridge Cannot Be Recognized) - TS3720 / TS3722". Canon's support-code article for the printer refusing to recognise an installed cartridge. Probed 2026-08-21: title-verified. What that article does not carry is the model boundary — it is written for a product line, and 5161C005 is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
My Canon imageCLASS MF455dw won't print colour documents in colour.+
It cannot — the MF455dw is a monochrome (black-and-white) laser, so it prints everything in black/greyscale by design; there is no colour toner. That is not a fault or a setting. If you need colour, a colour laser (like the MF656Cdw) or a colour inkjet is required. For high-volume, low-cost black text and documents, the mono laser is fast and economical.
My printer says the cartridge isn't recognised but it's brand new.+
Take it out and check two things: that every piece of protective tape, clip or cover is off — especially anything over the small copper chip — and that it clicks positively into place when refitted. Those two account for most of these messages on a new cartridge. If it still fails, wipe the chip contacts with a dry lint-free cloth.
My third-party cartridges stopped working after an update.+
Some firmware updates deliberately block non-genuine supplies, and that is a known outcome rather than a fault or a coincidence. It is worth knowing before you buy more of the same cartridges, because the printer is working as its current firmware intends.
Does this answer apply to every Canon model?+
No. It is scoped to 5161C005. Canon printer; PIXMA/MegaTank/MAXIFY/imageCLASS ink/toner systems and maintenance paths differ.
What should I record before troubleshooting cartridge not recognized or toner?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing cartridge not recognized, toner. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for leaking, swollen, damaged or hot supplies.
