Original OEM vs compatible: how to choose the right Epson T789 cartridge Dear Customer, the best choice depends on what you value most—maximum brand consistency or maximum savings. That’s why we keep both options ready: - Original OEM Epson T7891–T7894 – ideal if you want to stick to manufacturer supplies, keep identical colour behaviour across all devices, or follow strict internal purchasing policies.
- Compatible Epson T7891–T7894 (DrTusz.pl offer) – the smart option if you want to reduce printing costs while keeping the same daily dependability. Our compatible cartridges are as good as the originals in real-life office use: clear text, stable colours and smooth operation.
Practical tip: if you print mostly black-and-white, you’ll replace Epson T7891 black ink more often than colours. If you regularly print charts, logos or marketing materials, keep a spare Epson T7892 cyan ink, Epson T7893 magenta ink and Epson T7894 yellow ink on hand—so your workflow never stops mid-deadline. Common user issues—and how we help you fix them fast Even the best office printer can sometimes show signs of “print fatigue”, especially when it sits unused for a while or works in a dusty environment.

Often the culprit is not the cartridge itself—but clogged nozzles or a print head that needs maintenance.

- the printer hasn’t been used for a longer period
