Original OEM vs Compatible – how to choose the right cartridge for your MF820Cdn

When selecting an ink for Canon i-SENSYS MF820Cdn (in laser printers, “ink” is commonly searched, but the correct consumable is toner for Canon i-SENSYS MF820Cdn), it’s worth deciding what matters most: maximum brand consistency, or the best cost per page.

• Original OEM cartridges – made by Canon, designed specifically for the MF820 series. They’re a great choice if you want to stick to the manufacturer’s solution across the entire fleet.
• Compatible cartridges from DrTusz.pl – an excellent alternative for everyday business printing. Our compatible solutions are as good as originals in practical use: they deliver strong blacks, clean colour, and reliable performance while helping you reduce printing costs.

If you print a lot of colour documents, compatible CMYK sets are often the smartest option. If you print critical client materials and want to keep everything strictly OEM, the original line is ready for you too—either way, we help you match the right item to your printer.

Helpful tips and common MF820Cdn user issues we can help you solve

In everyday use, customers most often ask us about print quality drops, colour inconsistencies or printer messages that stop printing. Here’s what to check when selecting supplies for your Canon i-SENSYS MF820Cdn:

• Faded prints or uneven colour – usually indicates a toner nearing the end of its yield, or a drum unit that’s worn after heavy use.
• Lines, smudges, or background shading – often linked to the drum unit for Canon i-SENSYS MF820Cdn rather than the toner itself.
• Message about waste toner – replace the Waste Toner Tank Canon WT-A3 (9549B002) to restore normal operation.
• Correct colour selection – the MF820 uses separate cartridges for each colour (Black/Cyan/Magenta/Yellow). Choosing the correct code avoids mismatches.
