HP Designjet Z3100 Photo Printer Series - Insert a printhead

note:

If the printhead is new, shake the printhead vigorously before removing the protective caps.

1. Remove the orange protective caps by pulling them down.

2. Clean the bottom of the printhead by wiping it with the swab provided or with a cotton swab and de-ionized or distilled water.

     caution:

   Do not touch the electrical connections on the backside of the printhead.

3. The printhead is designed to prevent you from accidentally inserting it into the wrong slot. Check that the colored label on the printhead matches the colored label of the carriage slot into which the printhead is to be inserted.
4. Insert the new printhead into its correct slot in the carriage.

     caution:

   Insert the printhead slowly and vertically, straight down. It may be damaged if you insert it too fast, or at an angle, or if you rotate it as you insert it.

5. Push down as indicated by the arrow shown below.

     caution:

   When installing the new printhead there may be some resistance, so you need to press it down firmly but smoothly. You should hear a beep and see confirmation on the front-panel display that the printhead has been inserted.

6. Insert any other printheads, that need to be installed, with the same procedure, then close the carriage lid.

7. Ensure the end of the blue handle catches the wire loop on the near side of the carriage.

8. Lower the handle to rest on the carriage cover.

   When all the printheads have been inserted correctly and are accepted by the printer, the printer beeps.

   note:

   If the printer does not beep when you insert the printhead and the Replace message appears on the front-panel display, the printhead may need to be reinserted.

9. Close the window.

10. The front-panel display confirms that all printheads are correctly inserted. The printer starts checking and preparing the printheads. The default routine process, when all printheads are changed, takes 25 minutes. If the printer finds problems in preparing the printheads, it takes longer, up to 55 minutes. For a single printhead insertion, the times vary between 20 and 40 minutes. After all printheads are checked and prepared, the printhead realignment procedure runs automatically if paper is loaded.
