Identifying the Cause

Firstly, confirm the issue's consistency by printing several test pages. If the black spot appears in the exact same location on every print, this usually rules out software issues or random hardware errors, pinpointing the cause to something more mechanical or physical within the printer itself.

Running Preliminary Maintenance

You have already taken some initial steps by running the printhead cleaning and nozzle check functions. These are crucial first steps in resolving print quality issues. Since these did not resolve the black spot, additional steps are required. It’s worth mentioning that excessive printhead cleaning can deplete your ink levels significantly and should only be repeated a few times.

Manual Inspection and Cleaning

Here’s how to manually clean the printhead, which might resolve the issue if a small particle like lint or hair is causing the obstruction:

1. Power Down: Turn off the printer and unplug it to ensure safety before you begin any manual intervention.
2. Access the Printhead: Open the printer to access the printhead. Consult your printer’s manual for specific instructions as models may vary in design.
3. Visual Inspection: Use a flashlight to carefully inspect the printhead and surrounding area for any visible debris such as lint, dust, or hair. Even a small particle can cause repeated spotting.
4. Manual Cleaning:
   • Dip a cotton swab in distilled water or isopropyl alcohol and gently clean the printhead surface. Avoid using too much liquid.
   • Wipe away from the nozzles to avoid getting extra moisture in them.
   • You can also use a lint-free cloth to gently wipe the area.
5. Allow to Dry: Give the printhead ample time to dry completely before plugging in and powering up the printer.
6. Re-test: Once everything is reassembled and the printer is dry, run a test print to see if the issue persists.

When to Seek Professional Help

If the manual cleaning doesn’t resolve the problem, it may be necessary to consider professional servicing. Sometimes, issues like these can stem from internal damage or wear that requires more technical expertise.

Prevention Tips

To prevent future issues, ensure your printer is in a clean, dust-free environment. Regular maintenance, like running the built-in cleaning functions periodically and using good quality paper and ink, can also help maintain print quality.
