Steps
. The first troubleshooting step an owner can take is to make sure that the plastic protective tape on the new black cartridge is off.
Next,calibrate the HP printer. One thing to remember is that every time there is a need for a new printer cartridge, calibration is one of the steps to perform right after loading. You can run "Self Test Diagnostic," as well as, "Print Cartridge Alignment" in order to get the black ink to work.
You can also try cleaning the black ink cartridge. Remove the blank ink cartridge from the HP printer; use a cotton swab to clean the laser or scanner block. Wipe away dirt, grime or any dried ink that may prevent ink from flowing. You can also try cleaning the printer heads.
If you are having issues on an HP Laserjet printer, go to the menu, click "Diagnostics," then print the "PQ Troubleshooting Pages." If black ink does not print, go to "Disable the Cartridge" and switch the magenta and black cartridges on the menu. Then, print the pages again. If black ink does not print, then the problem may be the toner cartridge.
At times, when black ink does not print, it can signify a problem with a printer's laser. The owner of a HP printer may see an error on the LCD screen, indicating that there is a problem with the laser assembly.
Another problem could be the wiring connection at the laser or scanner; check if the plugs are loose. Contact HP Support for further assistance.
Hi
When printing, just adjust the PRINT QUALITY to PHOTO because I believe your print quality is set to TEXT. I am sure it will print move darker than before.
I hope it helps you solve your problem.
