Lightly dampen a lint-free cloth with warm water. Wipe the electrical contacts on the back of each printhead until clean, and set them aside. Locate the electrical contacts at the rear of each printhead slot in the carriage and gently wipe with an up-and-down motion until all of the ink is removed from the contacts.
Find the printhead drop detector beside the stored printhead carriage. Remove any debris blocking the printhead drop detector. With a dry lint-free cloth, wipe the surface of the drop detector to remove any non-visible debris. Close the window.
A printhead can usually be cleaned in one of two ways: through software on your PC or manually by taking out the printhead. Here`s a quick rundown of how you can clean your printer head from the HP experts: Run the “Clean Printhead” function from your computer.
With the automatic cleaning, the vacuum in the ink nozzles is sucked off and the print head with color, usually the print heads are here on the parking station, ergo maintenance position, where the vacuum is generated. In the case of the print head, suction is then also carried out from the color glands.
Soak the Printhead

Fill a bowl with warm water (or a mixture of water and vinegar to clean the printhead) and place the printhead directly in it. Let it sit for five minutes or so. Pull the printhead out of the water and use a lint-free cloth or paper towel to remove the dried ink.

The sponge end of a blocked printer head can be cleaned with only one liquid other than water. This liquid is isopropyl alcohol. Isopropyl alcohol isn`t strong enough to melt the sponge but is still strong enough to dissolve the ink inside the blocked printer head.
Use Isopropyl Alcohol (IPA) cleaning solution to clean printer exterior effectively and safely to avoid any printer damage.
Unlike traditional printers that pass the paper over movable printheads, HP PageWide printheads are stationary. The paper goes under the actually page-wide, immovable printhead, at an incredible speed, while thousands of tiny ink nozzles apply the HP Thermal InkJet color.
Cradle (Carriage) The portion of the printer where the inkjet cartridges are installed. This device also carries the inkjet cartridges back and forth across the page creating the desired image.
Dried Ink Buildup on the Printhead

If the print cleaning cycle doesn`t work, dried ink may be the culprit. Take the printhead out and wipe the nozzles clean to remove any buildup. Depending on the model of your printer, this may be difficult—some printheads are harder to remove than others.

HP Designjet 750C+
ANSWER : I was replacing the belt on my 750c and let the y-axis motor slip out of my hand. This caused the two wire terminals to disconnect from the motor. Does anyone know which terminals the white and black wires attach to? One of the terminals has a red dot beside it and I assume this is an indicator, but do not know which wire connects there. Any help would be greatly appreciated.
