Which printers use HP 831 ink?

HP 831 is a 775ml cartridge family used in supported standard HP Latex printer configurations.

The primary configurations covered by the HP 831 products and guidance on this page are:

HP Latex 360
HP Latex 365
HP Latex 560
HP Latex 370 in its standard, non-upgraded 775ml configuration

An HP Latex 360 or 370 may have an HP 3-liter upgrade kit installed. The installed configuration changes the ink-supply arrangement, so do not order for a Latex 360 or 370 based only on the model name.

Check the cartridge currently installed, review its reference number, and confirm whether the printer has been modified or upgraded before purchasing.

Using an HP Latex 360 or 365? Review our HP Latex 360/365 ink compatibility guide before ordering.

Important HP Latex 370 distinction

A standard, non-upgraded HP Latex 370 uses the 775ml HP 831-family arrangement covered on this page. Some Latex 370 printers, however, may have an HP 3-liter upgrade kit installed.

When that upgrade is present, verify:

Whether the 3-liter upgrade kit is installed
The cartridge or ink box currently connected to the printer
The reference number currently in use
The printer firmware and chip requirements
Whether the proposed aftermarket product is supported for that exact configuration

If these details are uncertain, contact us before placing an order.

HP 831 versus HP 871

HP 831 and HP 871 are different cartridge formats and should not be treated as interchangeable products.

HP 831: 775ml cartridge family used in supported standard HP Latex configurations.
HP 871: 3-liter cartridge family used in supported high-volume configurations such as the HP Latex 375 and HP Latex 570.
Upgraded HP Latex 360 or 370 systems: require additional verification because an installed 3-liter upgrade kit changes how ink is supplied.

The safest way to avoid a wrong order is to match all three:

Printer model
Installed configuration
Cartridge reference number currently in use

Before switching to aftermarket HP 831 ink

Changing ink suppliers can affect printer operation and output depending on the machine, firmware, media profiles, maintenance condition, and existing ink history.

Before switching:

Confirm the cartridge is intended for your exact printer and configuration.
Review any printer, service-contract, media-warranty, or manufacturer-warranty implications.
Do not assume an aftermarket cartridge carries the same certifications or warranty eligibility as an original manufacturer cartridge.
Follow the product supplier’s transition and installation instructions.
Consider testing color-critical production before changing an entire workflow.
Do not mix products or chemistries unless the supplier has confirmed the transition procedure.

We do not guarantee universal compatibility based only on an HP family name or reference number.
