Prepare to clean the printhead contacts
1. Ensure that you have the HP Latex 3000 Printer Cleaning Kit, which is provided with your printer.
2. Ensure that the printer is not printing.
3. Identify which printheads need cleaning, usually after the Internal Print Server recommends replacing
or reseating them.
4. Ensure that all windows, covers, and doors are closed and remain in their original position.
5. Move the printhead carriage to the service position.
6. Turn off the printer in the correct way for maintenance operations: see Turn the printer off on page 142 .
7. Stand on the folding steps and open the service position window.
Clean the printhead contacts (in the carriage slot)
1. Carefully remove the printheads that may need cleaning from the carriage and protect them using their
orange sealing caps.
CAUTION: Ensure that each printhead uses its own color cap. This is especially important with the
Optimizer printhead caps as there is a high risk of nozzle damage if they are used with the color
printheads and vice-versa. The optimizer caps are labeled as shown below.
