Refilling HP ink cartridges is one of the most effective ways to cut down on plastic waste and reduce costs. But if you’re building a backup set of refilled cartridges, it’s essential to store them properly to avoid ink drying, nozzle clogs, or damage.
This guide offers safe, sustainable methods for long-term cartridge storage using easy-to-find materials, plus practical tools we’ve used ourselves to keep printheads protected.
Why Store Multiple Refilled Cartridges?
HP printers (including the popular 60, 61, 62, 63, 64, 65, 66, 67, 68, 21, and 59 models) store a limited memory of cartridge serial numbers—usually 3 to 5 sets.
When you rotate between multiple refilled cartridges, the printer may treat previously used ones as “new” again. This means even reused cartridges may appear full, bypassing the low-ink warning. It’s an effective way to reduce waste and keep your printing uninterrupted.
But only if your refilled cartridges stay in working condition.
The 4-Step Method to Safe Cartridge Storage
1. Seal the Nozzle Area With Gentle Tape
Refilled cartridges can dry out quickly if their nozzles are left exposed. The first line of defense is using a low-tack tape that adheres gently to the printhead without damaging it.
We recommend a 3M Specialty Low-Tack Tape. This type of tape is designed specifically for delicate surfaces and is safe to use with HP integrated cartridges.
⚠️Avoid duct tape or packing tape—these can leave residue and damage the nozzle surface.
2. Add a Protective Storage Clip
After sealing the nozzles, apply light pressure using a clip designed for HP cartridges. This helps maintain contact between the tape and the nozzle plate, ensuring an airtight seal.
We use a reusable Protective Storage Clip for HP Integrated Cartridges, which works across most common cartridge sizes.
If you don’t have a clip, make sure the tape isn’t under tension that could peel it off during storage.
3. Store in an Airtight Bag With Moisture Control
Place each cartridge (with clip and tape applied) in a Ziploc-style plastic bag. For added humidity retention, insert a damp—but-not-dripping paper towel inside the bag. This helps prevent the nozzle from drying out, especially in dry or heated environments.
Pro tip: Use recycled plastic bags when possible to minimize environmental impact.
4. Keep in a Cool, Dark Place
Sunlight and heat degrade ink faster than you’d expect. Ideal storage conditions are:
-
Room temperature (around 60–75°F / 15–24°C)
-
Away from sunlight and radiators
-
Not in the fridge or freezer
Avoid storing cartridges in the garage or attic, where temperature swings are common.
Why This Matters
Each ink cartridge can take hundreds of years to decompose in a landfill. Refilling and properly storing cartridges increases their life cycle and reduces your overall waste output. It’s a small habit with a big environmental payoff.
