ONLYU 575XL & 576XL ink cartridges (Black & Tri-colour) for Canon PIXMA TS/TR series

At a glance

If you’re trying to keep a Canon PIXMA printer ticking over without paying for the most expensive originals, the ONLYU 575XL & 576XL combo pack is aimed at a very specific job: replacing Canon 575XL (black) and 576XL (tri-colour) cartridges with compatible ones.

On paper, it’s built around two things people actually care about day to day: clean, clear output for both text and colour, and cartridge capacity that means fewer swaps. That said, compatibility is only as good as the exact printer model match, so it’s worth double-checking your printer is one of the listed PIXMA TS/TR options before you buy.

What matters most for everyday printing

The brand positions these cartridges for “clog-free” style printing and consistent results. They’re described as using a nano-technology filtered ink layer intended to help deliver vibrant, clear and smooth prints. In practical terms, that’s the sort of promise that can matter if you print a mix of paperwork and occasional colour (forms, emails you need to hand in, school documents, invoices, and the occasional image).

There’s also a performance angle. The black cartridge is claimed to print at least 450 pages at A4 with 5% coverage, and the colour cartridge is also claimed at least 450 pages under the same coverage assumption. That doesn’t mean every user will hit the same numbers (coverage and document type vary), but it does suggest this pack is pitched at people who want more life between cartridge changes.

A small reality check: you still shouldn’t expect miracles if your printer sits idle for long periods. Even with “clog-free” claims, inkjet use patterns can make a difference, so regular printing (or running the printer’s maintenance routines when needed) helps.

Key compatibility notes (don’t skip this)

These ONLYU 575XL & 576XL replacements are stated as compatible with a specific set of Canon models: Canon PIXMA TS3550i, TS3551i, TS3750i, TS3751i, TS3752i, TR4750i, TR4751i, TR4755i, and TR4756i.

It makes sense if your printer is already in that list and you simply need a replacement cartridge set. It may not suit you if you’re unsure of the exact model (or if your printer is very similar but not listed). In that situation, it’s safer to confirm the model number from the printer itself or the packaging details.

Where it shines (and where it may feel limiting)

Where it shines: - Mixed home/office printing where you want sharp text and usable colour without constantly replacing cartridges. - Environments where you may need reliable prints for documentation, basic marketing material, or admin tasks (the listing even mentions contexts like home, office, healthcare, financial systems and retail).

Where it may feel limiting: - If you’re the sort of person who prints photos heavily and expects the most refined colour rendering across multiple paper types, compatible cartridges can be a bit of a gamble. The listing emphasises quality and smooth output, but it doesn’t provide detailed colour performance benchmarks. - If you rarely print, inkjet cartridges can still behave differently depending on printer maintenance and usage. The “clog-free” positioning helps, but it’s not a guarantee under all circumstances.

Quick overview: what you actually get

This is a combo pack covering the black cartridge and the tri-colour cartridge replacement. Each cartridge is described as individually sealed for safe delivery.

The listing also notes that packaging may vary, and you may receive a different outer package than before, although the product quality itself is said to remain unchanged. That’s fairly normal for compatible cartridge sellers, but it’s worth keeping in mind if you’re expecting the same packaging every time.

Getting the most from your replacement

When you install replacement cartridges, the best results usually come from being a bit methodical: - Ensure the cartridge types match your printer’s expectations (the model list matters here). - After fitting, let the printer complete any initial recognition/priming steps it asks for. - If you print text-heavy documents, run a quick nozzle check/cleaning only when the output shows signs of missing lines or streaks. Over-cleaning can waste ink.

Micro-example: if you’re preparing a week of household admin, fitting both cartridges before you start can prevent the annoying “I’m out of colour mid-document” situation—especially if you print the occasional form in colour.

Is it worth it?

A solid pick if you own a compatible Canon PIXMA TS/TR model from the list and you want a 575XL/576XL combo that’s geared towards clear printing and fewer replacements thanks to the stated 450-page-at-5% coverage capacity claims.

You may want to skip it if your printer model isn’t one of the explicitly listed ones, or if your use is highly photo-focused and you’re very particular about colour consistency across different paper types. In those cases, it’s worth weighing whether you’d rather choose a safer “known behaviour” approach.

Also keep expectations realistic: these are replacements, and performance can vary with your paper, coverage, and how often you print.

Are these cartridges compatible with all Canon PIXMA printers?

No. The listing names specific PIXMA TS/TR models, including TS3550i, TS3551i, TS3750i, TS3751i, TS3752i, TR4750i, TR4751i, TR4755i and TR4756i, so you’ll want to match your exact printer model.

Do they support both black and tri-colour printing?

Yes. This combo pack is described as including the black (575XL) and tri-colour (576XL) cartridges.

How long do the cartridges last?

The listing claims at least 450 pages for black and at least 450 pages for colour at A4 with 5% coverage. Real-world results can differ depending on what you print.

What packaging should I expect?

Cartridges are individually sealed, but the outer packaging may vary. The listing states the product quality itself should remain unchanged.

Will they clog less than other cartridges?

The description positions them as delivering clog-free printing results, but it doesn’t offer a detailed independent test. If you print infrequently, printer maintenance routines still matter.
