HP Officejet 6300 Series All-in-One - Color Image Prints in Black and White
The printer is working, but the printed output is in black and white when it should be in color.
This document applies to the following products:
Step one: Check the Print in Grayscale setting
Check for and remove any grayscale settings. Use the following steps to check this setting.
Step two: Check the ink levels
NOTE: The ink levels in non-HP, refilled, or remanufactured cartridges cannot be accurately read by the product.
Replace cartridges that are out of ink or low on ink. If the cartridges are not low or empty, continue to the next step now.
Step three: Print a self-test page
If the Print in grayscale option is not the problem and the print cartridges are not low on ink, print and evaluate a self-test page to determine if the cartridges or printer is causing the problem.
Step four: Note which cartridges printed which areas of the self-test page
Identify which cartridge printed which part of the self-test report so that if you find defects on the page, you will know which cartridge is the problem.
You can install different combinations of print cartridges in your printer, and different cartridge combinations print different self-test page patterns. Your self-test page might not look exactly like the picture below, but the right and left cartridges will print in the same areas of the page no matter which cartridges are installed.

Step five: Look for defects
In general, if the printer and print cartridges are working properly, the patterns (which look like grids of lines) should contain few or no missing lines. None of the colors should be missing and the colors of the blocks at the bottom of the page should match the labels below each block. Also, there should be no streaks of ink on the report.
NOTE: You can install different combinations of print cartridges in your printer, and different cartridge combinations print different self-test page patterns. Your self-test page might not look exactly like the pictures below.
Missing lines or streaked bars
If a pattern shows more than a few missing lines, or a bar is streaked, that print cartridge is not functioning properly.
Figure 3: The magenta pattern shows missing lines and the bar is streaked - the cartridge is not functioning properly
If the diagnostic page shows missing lines or streaked bars, click here to continue troubleshooting (c00635953) (in English).
The color blocks at the bottom of the self-test report are printed by the tri-color (left-side) cartridge only. These blocks have labels describing the color they should be. If the color of any of the blocks does not match its label, the left-side cartridge is not functioning properly.

If any of the color patterns or bars are entirely missing, the cartridge is not functioning properly.
NOTE: If you are printing in reserve mode, without all the cartridges installed, the patterns associated with the missing cartridge will also be missing.

If the self-test report shows smeared ink, you might need to clean your cartridges.

Step six: If you saw no defects
If no defects appear on the diagnostic page, the cartridges and product are probably working correctly. Click here to continue troubleshooting (c00635950) (in English).
