AI-generated summary
The Canon 5646C002 “Original Black” toner is one of those boring-but-reliable options that’s worth it if you want predictable print quality and you don’t want the hassle of returns or compatibility drama. For a UK office that mainly just needs consistent documents (invoices, letters, internal paperwork), paying for OEM is often the safest way to avoid weird streaking, uneven coverage, or headaches around “why is this suddenly smudging?” In that sense, £64.39 ex-VAT doesn’t feel outrageous for genuine Canon supply—especially if the printer you’re using is already tuned for Canon media and you care about low downtime.
That said, I’d be cautious if you’re printing high volumes and watching costs per page. OEM toner like this tends to cost more than alternatives, so if your priority is squeezing every penny out of total spend, a compatible/high-capacity option usually wins. Also, if you’ve had issues before with your model (frequent fusers, background toner, or poor maintenance), switching toner brand won’t fix the root cause—so make sure your printer is in good health. Bottom line: buy this if you want “set and forget” quality and minimal risk; think twice if you’re cost-per-page driven and printing lots.
