If you own an HP Designjet T120 printer, you may eventually need to replace the cutter. The cutter is an essential component that trims the printed paper, ensuring clean and precise edges. In this article, we will guide you through the process of replacing the cutter on your HP Designjet T120 printer.

Step 1: Prepare the Printer

Before replacing the cutter, ensure that your printer is turned off and unplugged from the power source. This step is crucial for your safety and to prevent any damage to the printer.

Step 2: Remove the Old Cutter

To remove the old cutter, open the top cover of the printer. Locate the cutter assembly, which is usually positioned on the right side. Carefully remove any tape or packaging material that might be securing the cutter in place. Then, gently lift the cutter assembly to detach it from the printer.

Step 3: Install the New Cutter

Take the replacement cutter and align it with the slot where the old cutter was positioned. Ensure that the cutter is inserted correctly and securely into the slot. Gently press down on the cutter assembly until you hear a click, indicating that it is properly installed.

Step 4: Test the Cutter

After installing the new cutter, close the top cover of the printer. Plug in the power cord and turn on the printer. Print a test page to verify that the cutter is functioning correctly. If the test page comes out with clean and precise edges, congratulations! You have successfully replaced the cutter on your HP Designjet T120 printer.

Tips for Maintaining the New Cutter

Now that you have replaced the cutter, here are some tips to ensure its longevity and optimal performance:

1. Clean the Cutter Regularly

Dust, debris, and ink residue can accumulate on the cutter over time, affecting its performance. Clean the cutter regularly using a soft cloth or cotton swab dipped in a mild cleaning solution. Gently wipe the cutter blades to remove any dirt or ink buildup.

2. Avoid Excessive Paper Jams

Paper jams can put extra strain on the cutter and cause it to wear out faster. To avoid paper jams, use high-quality paper that is compatible with your printer. Additionally, make sure that the paper is properly loaded and aligned in the tray before printing.

3. Replace the Cutter Blade if Necessary

If you notice that the cutter is not trimming the paper properly or leaving jagged edges, it may be time to replace the cutter blade. Contact HP customer support or refer to the printer’s user manual for instructions on replacing the cutter blade.

4. Schedule Regular Maintenance

To keep your HP Designjet T120 printer in optimal condition, schedule regular maintenance checks. This will help identify any potential issues with the cutter or other components and ensure that they are promptly addressed.


Replacing the cutter on your HP Designjet T120 printer is a simple process that can be done with minimal effort. By following the steps outlined in this article and implementing the maintenance tips, you can ensure that your printer continues to deliver high-quality prints with clean and precise edges.
