MY HPOFFICEJET ALL IN ONE SERIES 4620 WILL NOT PRINT IN BLACK WHEN YOU DO A ALIGNMENT PAGE THERES NO BLACK WRITING SO THE SCANNER SAYS COULD NOT DETECT ALIGNMENT PAGE ALIGNMENT FAILED WHAT CAN I DO NEW BLACK HP INK INSTALLED

I have a 4620, and had the same thing occur with the black ink. After a few hours on the phone with HP and them sending me a replacement printer that also wouldn't print, I found that there is a "vent" on the printer cartridges that if clogged, will cause that color not to print. The vent is on the top of the cartridge, facing up when installed into the printer. The vent looks like a "T". Unfortunately, the packaging that HP uses on these cartridges sometimes causes glue to clogged the vent. Take a sharp nail or straight pin, and clean out the vent. Hope this is successful for you.

Symptom that black cartridge faulty, if warranty applicable get replacement, if no clean cartridge nozzles through printer drivers properties>service>clean nozzles... try..

I would try to do a printhead cleaning cycle first. Then print an alignment page.
This will result in a good clear alignment page.

Perform the following steps to align the ink cartridges:

1. Disconnect the power cord from the unit, wait five seconds, and then plug it back in. This will reinitialize the unit.
2. Print another alignment test page. If the Press Enter to align message is not currently on the front panel display, complete the following steps to print an alignment page:
   1. Press Setup or Menu on the front panel (depending on the model).
   2. Press the right arrow button (>) until Maintenance or Tools is displayed, and then press Enter or OK (depending on the model).
   3. Press the right arrow button (>) until Align Print Cartridges is displayed, and then press Enter or OK (depending on the model).
3. To determine if the automatic alignment is functioning correctly, look into the output tray as the alignment page is printing; a blue light should be visible periodically on the page as the cartridges move back and forth. If this light is not visible, the product will not be able to align the cartridges and will require service. Service the product.
4. If the blue light is visible and the alignment pages are printing correctly, but the alignment pages still fails, there still may be a hardware problem with the unit.
   • If there are no other printing problems and you wish to continue, use the information in the Bypassing the ink cartridge alignment section below to bypass the alignment. The information from last successful alignment will be used.
   • If the message keeps reappearing or other print quality problems occur, service the product.

Models with a semi-automatic print cartridge alignment Some HP products have a semi-automatic alignment process. These models do not have an additional sensor and will print two pages for the alignment process instead of one. The alignment page must be placed on the scanner glass or into the automatic document feeder (HP Officejet V series) and scanned.

1. Disconnect the power cord, wait five seconds, and then plug it in. This reinitializes the product and forces the scanner to calibrate again.
2. Examine the scanner glass and white scan backing. Clean the scanner glass and scan backing if they are not clean. To clean the scanner glass and scan backing, use a soft cloth towel slightly dampened with clean water.
3. With the product turned on, open the scanner cover and check the bulb assembly. If the scanner bulb is not lit, the product must be serviced.
4. Verify that the alignment page is placed correctly on the scanner glass or in the ADF (if the product has one). Place the printed side down.
5. 5. Make a copy of the alignment page. The unit will make a copy even if the alignment message is displayed. Compare the copy to the original. If vertical lines appear in the copy, check to see if the scanner assembly requires cleaning. If cleaning the scanner assembly does not correct the problem, service the product.
6. 6. Use the information in the Bypassing the ink cartridge alignment section below to bypass the alignment. Operate the HP All-in-One to determine if there are other problems. The unit should be serviced if other error messages or problems occur or if alignment problems occur every time the ink cartridges are changed.

To bypass the ink cartridge alignment: Press and hold the Setup button, and then press Options (or Copy Options ).

This happened to me as well. Take your alignment page (or print another one) and put it in your scanner. The AIO printer will use the scanned alignment page to reconfigure your alignment.

After you print the alignment page, I think you have to then scan the page in the orientation that it asks you to.
By doing this, the scanner can tell if the printer alignment is correct.
