HP OfficeJet Pro 7740 Ink: Costs, Cartridges & Guide

Anyone who’s watched printer ink prices climb knows the ritual: wait for the low-ink warning, wince at the price, then wonder if third-party ink is worth the risk. The HP OfficeJet Pro 7740 makes that decision sharper, because its cartridge naming splits by region and prices stay premium. HP Canada (official HP store) lists the 7740 as designed for 952 and 952XL cartridges, while HP EMEA/Africa product specifications (official spec sheet) rate 953XL color at about 1,600 pages each.

Printer Model: HP OfficeJet Pro 7740 Wide Format All-in-One ·
Ink Cartridge Series: HP 952 and 952XL (North America) ·
High-Yield Color Yield: ~1,600 pages per cartridge (Best Buy Canada (electronics retailer)) ·
Cartridges per Set: 4 (black, cyan, magenta, yellow) ·
Ink Type: Pigment-based (HP Support Community (HP-run user forum))

A dozen specs, one pattern: high-yield cartridges change the economics of every page the 7740 prints.

What ink cartridges are compatible with the HP OfficeJet Pro 7740 printer?

Short answer: four individual cartridges, and the series name depends on which HP regional page you check.

HP 952 vs HP 953 cartridges

• HP Canada’s cartridge page lists the 7740 as designed for original HP 952 and 952XL cartridges (HP Canada (official HP store)).
• HP’s EMEA/Africa specifications list HP 953, 953XL, and 957XL support for the 7740 (HP EMEA/Africa product specifications (official spec sheet)).
• Best Buy Canada summarizes the same printer as using 952 standard or 952XL high-yield in North America (Best Buy Canada (electronics retailer)).

HP’s regional pages use different names for what is functionally the same ink family. Order by printer model, not by series name alone.

Official HP cartridges list

• Original part numbers listed by HP Canada include F6U15AN, L0S49AN, L0S52AN, L0S55AN, F6U19AN, L0S61AN, L0S64AN, L0S67AN, and N9K27AN (HP Canada (official HP store)).
• The 7740 takes four separate cartridges, so you replace only the empty color (HP Canada (official HP store)).

Third-party compatible options

• Compatible and remanufactured cartridges are sold widely, but HP does not list them as approved options (HP Support Community (HP-run user forum)).
• Best Buy Canada sells compatible alternatives alongside genuine cartridges, with prices below HP’s own (Best Buy Canada (electronics retailer)).
• If you try one, keep the packaging and receipt in case of leaks or early failure.

What this means: compatibility is simple — four cartridges from the 952/953 family — but regional naming is the trap. The cartridge number printed on your current cartridge is the one to reorder.

Why is HP ink so expensive now?

HP’s ink pricing looks irrational until you see what is inside the cartridge and what HP promises because of it.

Research and development costs

• HP’s support community describes 952-series ink as pigment based, fade resistant, and more water resistant than dye-based inks (HP Support Community (HP-run user forum)).
• The 7740 user guide specifies a cartridge design meant to run until empty — reliability engineering that cheaper cartridges do not advertise (HP OfficeJet Pro 7740 User Guide (manufacturer manual)).

Proprietary technology

• HP recommends original cartridges for consistent quality; the support forum says third-party ink can compromise print quality and reliability (HP Support Community (HP-run user forum)).
• HP states high-yield cartridges generally offer a lower cost per page and fewer cartridge changes, which is why the XL versions exist at a premium sticker price (HP Canada (official HP store)).

Comparison with third-party prices

• Retailers such as Best Buy Canada sell compatible cartridges below genuine HP pricing, which is why the price gap feels jarring (Best Buy Canada (electronics retailer)).
• HP’s published yields show the per-page gap narrowing when you move to XL cartridges (HP EMEA/Africa product specifications (official spec sheet)).

The catch: you are paying for reliability engineering and published yields, not just colored liquid — and the XL cartridge is where that engineering starts paying you back.

What is the cheapest way to buy HP ink?

The cheapest ink for the 7740 is not the cheapest cartridge; it is the one with the lowest cost per page.

Buying high-yield cartridges

• HP says high-yield cartridges generally offer a lower cost per page and fewer cartridge changes (HP Canada (official HP store)).
• Published yields: 953XL black around 2,000 pages versus 953 black around 1,000; 953XL color around 1,600 versus 953 color around 700 (HP EMEA/Africa product specifications (official spec sheet)).

Using HP Instant Ink subscription

• HP markets Instant Ink as a subscription that lowers per-page ink costs; eligibility changes over time, so confirm 7740 support on HP’s Instant Ink page before buying.
• The same value logic applies to the printer itself: our Best Budget 3D Printers 2026: Top Picks for Every Price Range guide ranks machines by running cost, not just sticker price.

Considering remanufactured or compatible cartridges

• Compatible cartridges are cheaper at checkout and widely stocked by retailers like Best Buy Canada (Best Buy Canada (electronics retailer)).
• HP’s support community warns that non-HP ink may damage the printhead or ink delivery system (HP Support Community (HP-run user forum)).

Where to find discounts

• The 957XL black cartridge, rated around 3,000 pages, is the lowest-cost-per-page black option in the 7740 lineup (HP EMEA/Africa product specifications (official spec sheet)).
• Buying genuine cartridges in the XL tier reduces how often you reorder, which cuts both cost and downtime (HP Canada (official HP store)).

The trade-off: genuine XL cartridges lose on sticker price but win on safety and per-page cost; compatible cartridges win the upfront price and make the printer the test bed.

How to replace ink for HP OfficeJet Pro 7740?

Replacing ink on the 7740 takes about two minutes, needs no tools, and is hard to get wrong once you know the release mechanism.

Preparing the printer

• Turn the printer on and open the cartridge access door; the carriage moves to the ink access area (HP OfficeJet Pro 7740 User Guide (manufacturer manual)).
• Keep the replacement cartridge packaged until you are ready to install it.
• HP’s manual says the printer is designed for cartridges to be used until they are empty; refilling early can cause the printer to fail (HP OfficeJet Pro 7740 User Guide (manufacturer manual)).

Removing the old cartridge

1. Wait for the carriage to stop moving in the access area.
2. Press down on the empty cartridge until it releases.
3. Pull the cartridge straight out of its slot.
4. Repeat for any other empty cartridges before installing replacements.

Installing the new cartridge

• Remove the new cartridge from its packaging, then pull off the protective tape.
• Touch only the plastic body; avoid the copper contacts and the ink nozzles.
• Slide the cartridge into the slot with the label facing up until it clicks into place.

Aligning cartridges

• Close the access door; the printer may prompt you to align or it may print an alignment page automatically.
• Follow the on-screen instructions; if an alignment page prints, place it face-down on the scanner glass when prompted.
• If alignment fails repeatedly, check that all protective tape was removed and reseat the cartridge (HP OfficeJet Pro 7740 User Guide (manufacturer manual)).

Is it okay to use an off brand of ink for my HP printer?

The honest answer: off-brand ink works for many 7740 owners in the short term, but HP’s own support community documents the risks.

Risks of off-brand ink

• Print quality: color consistency and reliability are the first things HP’s forum says third-party ink can compromise (HP Support Community (HP-run user forum)).
• Hardware: the same post says non-HP ink may damage the printhead or ink delivery system (HP Support Community (HP-run user forum)).

Warranty exposure

• HP’s support community notes that warranty issues can arise if damage is caused by non-HP ink (HP Support Community (HP-run user forum)).
• HP’s user guide keeps the design scope on original cartridges used until empty; anything else falls outside that tested design (HP OfficeJet Pro 7740 User Guide (manufacturer manual)).

The implication: off-brand ink is a budget play, not a reliability play. One bad cartridge can turn a $60 saving into a failed printhead, so test before you depend on it.

HP 952 standard vs HP 953 high-yield vs compatible cartridges: side-by-side

Three ways to keep the 7740 printing, one pattern: every dollar saved at the register shows up later in yields, frequency, or risk.

The pattern: genuine high-yield cartridges move the battle from sticker price to per-page cost; compatible cartridges only win if quality and hardware risk stay quiet.

HP OfficeJet Pro 7740 ink specifications

Eight numbers determine what the 7740 costs to run, one pattern: every extra page in a cartridge lowers the price of each sheet you print.

The trade-off: the 7740’s ink system is well engineered, but that engineering is exactly why the official cartridges carry the prices they do.

Upsides and downsides of the HP OfficeJet Pro 7740 ink system

The trade-off: a well-engineered ink system is a pleasure to maintain, and the same engineering keeps the official ink expensive.

What’s confirmed, what’s still unclear

The research pack settles cartridge compatibility completely; two questions genuinely remain open.

The takeaway: trust the confirmed list when you buy, and treat the unclear list as the fine print.

What HP documentation and users say about ink reliability

Three voices define the 7740 ink debate: a user’s experience, the manufacturer’s manual, and a retailer’s yield data.

“HP 952 ink cartridges are pigment based. They are fade resistant and more water resistant than dye based inks.”

— HP Support Community user (2019), in HP Support Community (HP-run user forum)

“The printer is designed for ink cartridges to be used until they are empty.”

— HP OfficeJet Pro 7740 User Guide (manufacturer manual)

“HP 952 black cartridges are commonly rated around 700 to 1,000 pages and HP 952XL black cartridges around 2,000 pages, with actual output varying by document and settings.”

— Best Buy Canada (electronics retailer)

Why this matters: HP’s credibility rests on print quality, and both the manual and retailers keep repeating the same caveat — yields are estimates until your documents prove otherwise.

Summary: the real cost of HP 7740 ink

HP’s ink pricing makes sense once you stop looking at sticker price and start looking at yield. For 7740 owners, the practical move is high-yield 952XL or 953XL cartridges — about 2,000 black pages and 1,600 per color at HP’s published ratings (HP EMEA/Africa product specifications (official spec sheet)) — with one genuine spare for deadline moments. If budget pressure pushes you toward compatible cartridges, test a single cartridge before committing to a full set, because HP’s own forum documents print-quality and hardware risks (HP Support Community (HP-run user forum)). For anyone printing from a small office or home office, the choice is clear: price your per-page cost before you click buy, or overpay for ink every single time.
