I have a HP LaserJet P1006 printer with me. While printing some photos, the first few came just fine. Then the photos started coming out as black and white. I didn't touched or changed any settings. The ink cartridges are full. I have tried replacing both cartridges, but it still doesn't work. When I print an alignment page it prints fine and the printer aligns itself, but still no color. Do anyone have any idea why it is happening so?
