Printhead troubleshooting If you have a problem with a printhead, try these suggestions. 1. Check that you have the correct type of printhead (model number). 2. Check that you have removed the orange protective caps from the printhead. 3. Check that the printhead is correctly oriented: compare it with the others. 4. Check that you have closed and latched the printhead cover. 5. If you still have problems when printing, see Print quality on page 172. Cleaning container The cleaning container is a replaceable part that collects waste ink in liquid form, with a capacity of about 5 liters. The cleaning container is designed to keep the printer's waste ink from damaging the printer and dirtying its surroundings. In order to achieve these objectives, you must ensure that it is correctly installed and maintained, changing it when prompted by the front panel. TIP: You are recommended to wear gloves when replacing the cleaning container. Always replace the cleaning container with the printer switched on, otherwise the counters may not work properly. IMPORTANT: After removing the cleaning container, close it with the cap. If the printer continues operating while the container is incorrectly installed or connected, HP will not be responsible for any resulting damage or cleaning expenses. You can check the cleaning container status in the front panel. Cleaning container status ● Ready ● Missing: The cleaning container is not detected. ● Almost full: This is estimated by the printer. ● Full: The printer has stopped printing. It will continue after the cleaning container has been replaced. 88 Chapter 3 Ink system ENWW
