What Ink Does the HP OfficeJet Pro 9125e Use?

Quick answer: The HP OfficeJet Pro 9125e uses HP 936 ink cartridges (Black, Cyan, Magenta, Yellow), with HP 936XL — also sold as HP 936e EvoMore — high-yield versions available for higher-volume printing.

HP OfficeJet Pro 9125e Ink Cartridges at a Glance

The cartridges that ship in the box are lower-yield "Setup" versions meant to get you started — that's why some new owners see a low-ink warning sooner than expected. Retail HP 936 and HP 936XL cartridges print significantly more pages.

HP+ and Ink: What You Need to Know

The 9125e offers optional HP+ enrollment during setup. Choosing HP+ typically lowers the printer's up-front price and includes a free trial of Instant Ink, but it requires an HP account, an ongoing internet connection, and — critically — locks the printer to genuine HP ink cartridges for its lifetime via dynamic security measures enforced through firmware updates. Skipping HP+ at setup costs more up front but keeps the printer open to HP 936/936XL cartridges from any retailer as well as reputable third-party compatibles.

Save on HP 936 Ink

Castle Ink's HP ink lineup doesn't currently include the HP 936 family, so we can't offer compatible HP 936 cartridges for the 9125e today. For this printer, genuine HP 936/936XL (or HP 936e EvoMore) from HP.com or Amazon is your most reliable option. If you also own other HP inkjets, Castle Ink carries compatible cartridges for many other HP families — browse HP ink cartridges at Castle Ink.

How to Replace Ink in the HP OfficeJet Pro 9125e

1. Open the ink cartridge access door on the front of the printer.
2. Wait for the carriage to move to the center, then squeeze the tab on the empty cartridge and pull it straight out.
3. Remove the new cartridge from its packaging and pull off the plastic tape — avoid touching the copper contacts or ink nozzle.
4. Slide the cartridge into its matching color slot at a slight upward angle and push until it clicks into place.
5. Close the access door. The printer will automatically align and calibrate the new cartridge.

Troubleshooting Tips

• Cartridge not recognized: Remove it, wait 10 seconds, and reseat it firmly until it clicks.
• Faded or streaky prints: Run the built-in Print Quality Diagnostic from the touchscreen or HP Smart app, then a head cleaning if needed.
• Third-party cartridge rejected: This typically means HP+ is enabled — you'll need genuine HP ink, or you can factory-reset before HP+ activation if you haven't yet completed setup.
• Low-ink warning right after setup: Normal — the in-box "Setup" cartridges hold less ink than retail cartridges.

Frequently Asked Questions

HP 936 or HP 936XL? Both fit; the XL (936e EvoMore) version prints roughly twice as many pages per cartridge and costs less per page.

Can I use third-party ink? Only if you skipped HP+ enrollment at setup. HP+ printers use dynamic security to block non-HP chips.

Why did my ink run out so fast? The included "Setup" cartridges hold less ink than the retail HP 936 cartridges you'll buy later.

Does Castle Ink sell compatible HP 936 ink? Not currently. We recommend genuine HP 936/936XL for this printer until that changes.

Bottom Line

The HP OfficeJet Pro 9125e uses HP 936 (or HP 936XL / 936e EvoMore) cartridges in black, cyan, magenta, and yellow. Whether you can use third-party ink comes down to one choice made at setup: enrolling in HP+ trades ink flexibility for a lower price and free Instant Ink trial months.
