Maintaining Printheads
NOTE:
Do not clean a printhead unnecessarily, as this wastes ink and shortens the life of the printhead.
If you notice a decline in print quality, such as lines or dots missing from printed text or graphics, it does not mean that your ink cartridges have low ink levels. It may be an indication that your printheads need to be cleaned.
To clean the printheads
1Open the HP 2000C Toolbox. For details, see ÒUsing the HP 2000C ToolboxÓ in the ÒUsing Your Printer Driver SoftwareÓ section of this UserÕs Guide.
2Click the Services tab.
3Select Clean the Printheads, and follow the instructions on your computer screen.
Replacing a Printhead
NOTE:
Do not permanently remove a printhead until you are ready to replace it. The printer will not print unless all printheads are in place and in good working condition. However, you can temporarily remove and reinsert a printhead into its socket as part of a troubleshooting process.
The HP selection number on ink cartridges and printheads makes it easy for you to find the correct HP printing supplies for your HP 2000C printer. Determine the color of the printhead you need, then make sure you purchase or
order an HP No. 
Printhead for that color. See ÒOrdering Parts and AccessoriesÓ in this UserÕs Guide for printhead part numbers and ordering information.
