Page output and capacity across 812 cartridges
High-volume office printing rapidly depletes standard capacity inks. The Epson 812 series uses ISO/IEC 24711 test standards to calculate yield. Standard 812 black cartridges provide approximately 350 pages, while 812XL yields up to 1,100 pages and 812XXL yields up to 2,200 pages for extended printing.

Maintenance Components
Beyond ink cartridges, high-volume printers utilise maintenance components to collect surplus ink during routine printing cycles. These dedicated parts assist in maintaining continuous print quality during heavy work sessions.
Pro Tip
When replacing cyan, magenta, or yellow cartridges, opt for 812XL high-yield options rather than standard 812 cartridges. The XL variants contain over three times the ink, significantly reducing per-page printing costs during large colour print jobs.
Frequently Asked Questions
Can I mix standard 812 and high-yield 812XL cartridges in the Epson WorkForce WF-7845?
Yes, you can mix standard 812 and high-yield 812XL cartridges across different slots. For instance, you can install an 812XXL black cartridge alongside standard 812 colour cartridges without compatibility issues.
What is the difference between 812XL and 812XXL cartridges?
The 812XL size is available in all four colours (black, cyan, magenta, and yellow) yielding up to 1,100 pages per cartridge. The 812XXL extra high-yield cartridge is exclusively available in black, delivering up to 2,200 pages for high-volume monochrome printing.
Why does cyan or yellow ink drain even if I print predominantly black text?
Epson WorkForce printers periodically perform automatic ink maintenance cycles across all channels to keep printhead nozzles clear. Additionally, micro-drops of colour ink are sometimes blended into composite grey shades to enhance text sharpness.
