How do I change the black printhead of an HP Officejet 7130xi?

It is likely that the black portion of your printhead has become dried/blocked. I would advise running 1-3 cleaning cycles from your printer or printer software.

are you using hp original cartridges? if not, then thats probably the issue!

Materials needed: New empty syringe (big one) Gloves (to protect your hands fromink) Alcohol Paper tissue (to clean the excessink) Empty Plastic bottle (Here you putthe ink from the syringe) Important: Ensure that you have put new blackink cartridge to K8600. Ensure that the printhead arerecognized by the printer or no light alarms. Instruction: Press the Power button to turn onthe printer. Test print in microsoft excel with4 color black/yellow and cyan/magenta. If black only is missing means youhave clogged problem from the host. Wear your globes, prepare thematerials needed. Open the top cover. Press and hold the Resume buttonuntil the carriage moves to the left. CAUTION: Be careful not to proceed until the carriage is on the left sideof the printer. If the carriage does not move to the left automatically, turnthe printer off and back on and then try holding down the Resume button again.The printhead can be damaged if the carriage is not all the way to the left forinstallation. Lift the printhead latch. Lift the handle of a printhead anduse it to pull the printhead black/yellow out of its slot. Put printhead in thepaper tissue upward. Your printer are still ON becarefull not to touch the flex copper circuit. Get your syringe, use this to pullthe ink from the nozzle cap ( see link picture) After the done the syringe method,Insert the printhead black/yellow into its color-coded slot. Press down firmly on the printheaduntil it snaps into place. Pull the printhead latch all theway forward, and then press down until the latch engages. Close the cover. The printer should align theprintheads automatically in a few minutes, printing an alignment page. Print a test with black color only,If it does not print, try to change the Printhead. This is the only solution I foundin my HP k8600 black ink problem.

check the printhead.... print a print quality page from the settings button select print reports then print that page. there is a printhead health area as well as color blocks if there is streaks in the black yellow blocks or says poor the black/yellow printhead needs to be replaced. if it says good call hp for further troubleshooting and possible replacement under warranty

go into your driver and change your color preferences to black and white. that way when you want to print color you actually have to tell it to do so. which will save your color ink, and will print much faster. full color printing of a black and white document uses all ink colors except black to make what is called process black.

call the manufacture or tech support. Maybe there is a printhead reset on the printer??

It's probably like my Epson...the heads are eithr dirty or misaligned...you should have a computer diagnostic program on CD for your printer if you bought it new...if not, then you can get it from HP or possibly their webpage. The program should include an easy-to-follow alignment procedure done by a USB connection from your comp to your printer, or do the normal head cleading procedure at a service center.
