Before starting the ink replacement process, confirm that your HP OfficeJet 9012e printer is powered on. This is essential as the printer needs to be in an active state for the cartridge-related operations to function properly.

To reach the ink cartridges, open the front cover of the printer. Once the front cover is open, lift the ink access door. As soon as you do this, the ink cartridge carriage will start to move automatically. It's crucial that you wait patiently until the carriage comes to a complete stop. Proceeding while the carriage is still moving can lead to damage or improper cartridge replacement.

When it's time to release an old ink cartridge, simply push the cartridge forward. This action unlocks it. After unlocking, you can then smoothly pull the cartridge out of the printer.

Now, take your new LEMERO HP 9012e ink cartridge. To prevent any potential mess, it's advisable to open the new cartridge over a sink or a garbage can. Sometimes, during the manufacturing process, ink cartridges can be overfilled, which may cause leakage when opened. When handling the new cartridge, make sure to only touch the black plastic part. Before installing it, carefully remove the brightly - colored covering tape. If there's a plastic protective case around the cartridge, remove that as well.

Insert the new HP OfficeJet Pro 9012e ink cartridge into its corresponding slot. Push the cartridge in gently. You'll know it's in the correct position when you hear a distinct click. This click indicates that the cartridge has been properly seated.

After the cartridge is installed, close the ink access door and then put the front cover of the printer back into its original position.

HP OfficeJet Pro printers are designed to work with a variety of ink cartridge models. If you're unsure which cartridge your HP OfficeJet Pro 9012e printer uses, there are a couple of ways to find out. You can refer to the user's manual that was included with your printer when you purchased it. The manual contains detailed information about the printer's specifications, including the compatible ink cartridges. Another option is to check the cartridge that is currently installed on your printer. On the front or side of the cartridge, there is a label or sticker. This label displays the model number, which is a combination of letters and numbers. For example, the HP OfficeJet Pro 9012e printer uses the HP 962 ink cartridge for standard-yield printing and the HP 962XL for high-yield printing. For more in-depth details, click on the “What ink does my printer use?” page, and you'll be directed to the relevant information.

In terms of physical size and compatibility with the printer, the 962 and 962XL ink cartridges are quite similar. The key differentiator between these two cartridges lies in their ink volume. The HP 962XL ink cartridges have a larger ink capacity. As a result, they can produce more prints compared to the standard-yield HP 962 ink cartridges. The standard-yield HP 962 ink cartridges are capable of printing up to 1,000 pages for black and up to 700 pages for cyan, magenta, and yellow. In contrast, the high-yield HP 962XL ink cartridges can print up to 2,000 pages for black and up to 1,600 pages for cyan, magenta, and yellow, based on a 5% coverage level.
