Did you follow the alignment procedure after changing the ink cartridge? If not complete the alignment.

To replace the print cartridges
1. Make sure the HP All-in-One is on.
CAUTION: If the HP All-in-One is off when you open the print cartridge door to
access the print cartridges, the HP All-in-One will not release the cartridges for
changing. You might damage the HP All-in-One if the print cartridges are not
docked safely when you try to remove them.

2. Make sure you have letter or A4 unused plain white paper loaded in the input tray.

3. Open the print cartridge door.
The print carriage moves to the far right side of the HP All-in-One.

4. Wait until the print carriage is idle and silent, and then lightly press down on a print
cartridge to release it.
If you are replacing the tri-color print cartridge, remove the print cartridge from the
slot on the left.
If you are replacing the black or photo print cartridge, remove the print cartridge from
the slot on the right.

2 Print cartridge slot for the black and photo print cartridges
5. Pull the print cartridge toward you out of its slot.
6. If you are removing the black print cartridge in order to install the photo print cartridge,store the black print cartridge in the print cartridge protector or an airtight plastic container.

7. Remove the new print cartridge from its packaging and, being careful to touch only
the black plastic, gently remove the plastic tape by using the pink pull tab.
1 Copper-colored contacts
2 Plastic tape with pink pull tab (must be removed before installing)
3 Ink nozzles under tape

CAUTION: Do not touch the copper-colored contacts or ink nozzles. Touching
these parts can result in clogs, ink failure, and bad electrical connections.

8. Slide the new print cartridge forward into the empty slot. Then gently push the upper
part of the print cartridge forward until it clicks into the socket.
If you are installing the tri-color print cartridge, slide it into the left slot.

button next to OK.

cartridges, the alignment will fail. Load unused plain white paper into the input
tray, and then try the alignment again.

Aligning Ink Cartridges Your printer automatically aligns the ink cartridges when they are installed or replaced. To verify your ink cartridges are aligned, you can print an alignment page. After you close the printer unit, press the Menu button. The alignment page begins printing. During printing, the operator panel display reads Alignment Page Printing. When complete, the message reads Auto Alignment Complete. Your ink cartridges are now aligned for optimal print quality.
You may also need to align ink cartridges when characters are not properly formed or are not aligned at the left margin, or when vertical or straight lines appear wavy.
To align the ink cartridges:

1. Load plain paper. For more information, see Loading Paper.
   
   
2. Click Start® Programs or All Programs® Dell Printers® Dell Photo AIO Printer 922® Dell Printer Solution Center.
   
   
3. Click the Maintenance tab
   
   
4. Click Align to fix blurry edges.
   
   
5. Click Print.
   
   

The ink cartridges align when the page prints.

Be sure to run the print test page after installing cartridges.  After doing so, place the page face down on the scanner and select cartridge alignment.

Did you run the print sample page used to align the print cartridges by scanning the test page?

The reason is that your colour cartridge has run out of ink. You need to replace your colour cartridge as well and try the alignment process again.
