Compatible Canon C-EXV14 drum: fitting, chip reset and real savings | Star Toner

July 11, 2026 Updated August 30, 2026

The compatible Canon C-EXV14 drum is the imaging unit you need when your Canon imageRUNNER machine starts producing copies with vertical streaks, grey background areas or faded text. These symptoms almost always point to a worn-out drum, not the toner.

What it is and which printers it fits

The drum (or imaging unit) is the photosensitive cylinder that receives the charge and transfers the toner onto the paper. It is a separate part from the toner cartridge and has its own service life, usually far longer. This C-EXV14 is compatible with the following machines:

Canon imageRUNNER 2016, 2018, 2020, 2022, 2025 and 2030
Canon imageRUNNER 2230 and 2270
Canon imageRUNNER 2520, 2525, 2530, 2535 and 2545

If your model is on this list, the drum fits mechanically and electrically with no adapters or intermediate parts.

How to fit it and what to do if the "cartridge is not recognised"

Replacement is straightforward: switch off the machine, open the front cover, remove the used drum unit by pulling firmly on the tab and slide the new one in until it stops. Do not touch the green surface of the cylinder and protect it from direct light while handling it.

These imageRUNNER machines run the drum and toner separately, so if the copy still shows defects after the change, also check the condition of the toner cartridge. If the panel shows a persistent alert, try this order:

Switch the machine off and on so the system re-reads the consumable.
Check that the unit is fully seated and the cover is properly closed.
Make sure no transport tape or seal has been left on the drum.

If you want to confirm that print quality is correct after fitting, you can use our downloadable CMYK print test page.

Yield and savings compared with the original

A quality compatible drum offers the same duty cycle as the original: here we are talking about around 50,000 pages per unit. The difference lies in the cost per copy, noticeably lower without sacrificing sharpness or reliability. If you are unsure between original and compatible, we ran the real test in our article original vs compatible printed side by side.

To work out how much you can reduce your annual printing spend, it helps to understand the real cost of printing, taking into account the drum, toner and monthly volume.

Frequently asked questions

Is the C-EXV14 drum the same as the toner?

No. The drum (imaging unit) is the photosensitive cylinder that transfers the toner onto the paper, whereas the toner is the powder that forms the image. They are two separate consumables with different service lives; on these imageRUNNER machines they are replaced separately.

How many pages does this drum yield?

It offers an approximate yield of 50,000 pages to ISO standard, similar to the original drum, always depending on the type of jobs and the print volume of your machine.

Will my Canon imageRUNNER give an error when using a compatible drum?

These imageRUNNER models do not block third-party consumables via a chip, so they rarely show alerts. If a message appears after the change, switch the machine off and on and check that the unit is properly seated and free of seals.
