Frequently Asked Questions
Can I mix standard 937 and extra high-yield 937e cartridges in the HP OfficeJet Pro 9720?
Yes. Standard 937 (4S6W5NA) and extra high-yield 937e (4S6W9NA) cartridges share identical physical dimensions and operate in any combination within the printer.
How do wide-format A3 prints affect expected ink cartridge yields?
ISO/IEC 24711 yields are calculated using standard A4 test pages at approximately 5% ink coverage. Printing A3 documents or high-density graphics consumes significantly more ink per page, causing cartridges to deplete faster than their rated A4 page count.
Why is black ink consumed even when printing exclusively in colour mode?
HP office inkjet printers utilise black ink for crisp border rendering and text contrast during graphic print jobs, maintaining print clarity while consuming ink across both black and colour channels.
