• Use a lint-free cloth slightly dampened with distilled water.
• Gently clean the gold-colored contacts.
• Allow them to dry completely.
• Reinstall the cartridges.

Avoid touching the contacts with your fingers.

Clean the Printhead

A clogged printhead may trigger HP printer error 0xc19a004a.

Use the Built-In Cleaning Tool

1. Open Printer Maintenance.
2. Select Clean Printhead.
3. Complete the cleaning cycle.
4. Print a diagnostic page.

If necessary, repeat the cleaning one or two more times.

Perform a Semi-Full Reset

A reset restores several internal settings and often clears ink system failures.

Reset Steps

1. Turn off the printer.
2. Disconnect the power cable.
3. Wait one minute.
4. Hold the Power button while reconnecting the power.
