HP Latex 3000 Printer - Manual (Page 107)

3. Tilt the printhead a little before taking it completely out of its pocket.
4. If the printhead is to be reused, protect it using its orange sealing cap.
CAUTION: Make sure each printhead uses its own cap and not the cap for some other printhead. This is
especially important with the optimizer printhead caps as there is a high risk of nozzle damage if they
are mixed with the color printheads and vice versa. The optimizer caps are labeled as shown below.
NOTE: Remember which printhead came from which slot; the printer will report an error if you later replace
a printhead in a different slot.
Insert a printhead
1. Check that the new printhead is of the correct colors.
NOTE: Each printhead has a unique shape and cannot be inserted into the wrong slot. Do not try to
force it.
2. Shake the printhead according to the instructions on the packaging.
