简介
This guide provides direction on cleaning the print-head in your HP DeskJet 3524 printer. The print-head is the mechanism which transfers ink onto the paper. The HP DeskJet 3524 user manual also provides additional directions for cleaning the print-head.
你所需要的

-
Power on the printer.
-
To access the cartridge door, locate the two tabs on the left and right side of the printer. Lift up on the tabs and the print wagon will move into the access area.
-
After the wagon is accessible, the print-head will center itself in the printer. Once it is centered, remove the ink cartridges. To do this, press on the front tab of each cartridge. After the cartridges are removed, wrap them in a paper towel and set them to the side.
-
With the print-head still accessible in the center, power off the printer and unplug the machine.
-
-
-
Next, locate the seven torx screws (highlighted in red circles). To avoid confusion when reassembling later, we suggest drawing a picture of the printer and taping the screws to the image.
-
After removing the seven screws, loosen the lever from the scanner compartment.
First remove the lever so you can access the two top screws. Remove the lever by pulling it while pushing its top hinge.

-
In the second and third pictures, you will see 2 black plastic buttons. Push on the buttons and the display unit will separate from the orange cover.
-
When reassembling, ensure the white flat ribbon cable is correctly attached. If it is not attached correctly, you will be unable to push the orange cover closed.

-
The printed circuit board (PCB) is the flat green object perpendicular to the printer.
-
Gently remove the PCB by unscrewing the two torx screws (highlighted in red circles).
-
Prepare to remove the flat cables attached to the PCB. They are also connected to the print-head.
Screws for PCB are not required to be removed. You can try to take cable out white PCB is in its place.

-
When reassembling the print-head, ensure the black lint is under the black connector (see photo). If the blink lint is above the connector, you will receive a "wagon error" code. The wagon will essentially hit the right side of the printer, unable to go tot he left side.
-
After the printer is reassembled, print an "alignment page" and a "cleaning print head page."
If you still get bad print results, do a few “clean print head” and “align page” and see the quality of the print each time. It should get better (I started getting a good print out after 5th attempt)

To reassemble your device, follow these instructions in reverse order.

Hi Thomas,
Did you checked the black ribbon/ lint is in the correct place?

Thanks for this guide. I used it on my HP3525. I added one step which was to put a few millimeters of distilled water in a small dish and stood the printheads in the water for a few minutes then I gently lifted and lowered the printheads. The amount of black ink that came off was amazing. My first print was almost perfect.
