HP DesignJet T520 T120 Printhead Repair

If you own an HP DesignJet T520 or T120 printer, you may have experienced issues with the printhead. A malfunctioning printhead can cause poor print quality, color inconsistencies, and even printing errors. Fortunately, fixing the printhead is often simpler than it seems. Let’s dive into how to resolve this issue and get your printer back in action.

Identifying the Problem

Before jumping into repairs, make sure your printer’s problem is indeed with the printhead. Common signs include blurry prints, missing colors, or smudging. You may also notice error messages about the printhead or ink cartridges. Diagnosing the problem first helps save time.

Gather Necessary Tools

To fix the printhead on your HP DesignJet T520 or T120, you’ll need a few tools. You’ll need a clean microfiber cloth, distilled water, and replacement ink cartridges if the current ones are damaged. Always use distilled water to avoid mineral buildup.

Remove the Printhead

Start by turning off the printer and unplugging it to ensure safety. Gently open the printer cover to access the printhead. Carefully lift the printhead latch and remove the printhead assembly from the printer. This step should be done with caution to avoid damaging the delicate components.

Clean the Printhead

Over time, ink can dry and clog the printhead nozzles. Use a microfiber cloth lightly dampened with distilled water to wipe away any dried ink. Gently scrub the printhead nozzles to clear any blockage, but avoid aggressive scrubbing to prevent damaging the printhead.

Check for Blockages

Inspect the printhead for any visible ink blockages or debris. A simple blockage could be the cause of your print quality issues. If you notice a stubborn buildup, consider soaking the printhead in distilled water for about 10-15 minutes to loosen the ink.

Reinstall the Printhead

Once cleaned, carefully reinstall the printhead back into its slot. Ensure it is properly seated to avoid further issues. Close the printer cover and plug the printer back in. The printer should automatically recognize the printhead after a few moments.

Run Printer Diagnostics

After reinstalling the printhead, it’s a good idea to run the printer’s diagnostic tool. This tool can help identify any remaining issues with the printhead. Many HP printers offer a built-in cleaning cycle to ensure the printhead is working optimally.

Consider Replacing the Printhead

If cleaning the printhead doesn’t resolve the problem, it might be time for a replacement. Over time, printheads can wear out, especially with frequent use. If your printhead shows signs of damage, replacing it will restore your printer’s functionality.

Disadvantages of the HP DesignJet T520 & T120

While these printers offer great quality and efficiency, they do come with a few drawbacks. Printhead clogs can be frequent, particularly with prolonged inactivity. Additionally, ink consumption may be higher than expected, especially for large-format prints.

Conclusion

Fixing the printhead on your HP DesignJet T520 or T120 printer can be a straightforward process if you follow the correct steps. Regular maintenance, such as cleaning the printhead, will prolong its lifespan and improve print quality. However, if the issue persists, don’t hesitate to replace the printhead. Happy printing!
