Does it say "cartridge jam" or "jam in cartridge area"?

If it is the latter open the door and remove the jam.
Then press the SELECT button to continue.

Using the REPORTS MENU print the "color supplies status". Make sure everything is good.
Select SYSTEM SETUP. Select PRINT QUALITY. Select CALIBRATE COLOR. Select CALIBRATE NOW.
Check the Transfer Belt(ETB) which is inside the front door. Make sure that it is free of your "racing stripes".
You can use HP TOOLBOX to troubleshoot.
You are using HP cartridges???

The cartridge is missing contact from the drum to the ground. When this contact is missing, the charge from the the laser exposed areas on the drum cannot disappear and the result is lack of image.
Remove the cartridges and compare the connecting pins of the nest for the black with other nests. One may be bend and loosing it's contact.

when you open the front of the print you will see the streaks on the black transfer sheet.

Close the front door half way or until all the cartridge doors open.
You will see the same streaks on the problem cartridge(s) as on the transfer sheet.

Change that particular cartridge, let the printer recalibrate, and presto streaks are gone.

HP Color LaserJet 2600n Printer - Installing Print Cartridges When a print cartridge approaches the end of useful life, the control panel displays a message recommending that to order a replacement. The printer can continue to print using the current print cartridge until the control panel displays a message instructing to replace the cartridge. The printer uses four colors and has a different print cartridge for each color: black (K), cyan (C), magenta (M), and yellow (Y). Replace a print cartridge when the printer control panel displays one of the following messages: Replace yellow cartridge, Replace magenta cartridge, Replace cyan cartridge, Replace black cartridge. The control panel display also indicates the color that should be replaced (unless a genuine HP cartridge is not currently installed). Change the print cartridge

1. Turn off the printer.
2. Open the front door. CAUTION: Do not place anything on the transfer belt (ETB), which is located on the inside of the front door.
3. Remove the used print cartridge from the printer.
4. Remove the new print cartridge from the bag. Place the used print cartridge in the bag for recycling.
5. Grasp both sides of the print cartridge by the blue handles and distribute the toner by gently rocking the print cartridge from front to back. CAUTION: Do not touch the shutter or the surface of the roller.
6. Remove the orange shipping locks and the orange shipping tape from the new print cartridge. Discard the shipping tape and shipping locks according to local regulations.
7. Align the print cartridge with the tracks inside the printer, and using the handles, insert the print cartridge until it is firmly seated.
8. Firmly close the front door.

   NOTE: If a cartridge is in the wrong slot or is the wrong type for the printer, the control panel will display one of the following messages: Incorrect yellow, Incorrect magenta, Incorrect cyan, Incorrect black.
10. Installation is complete. Place the used print cartridge in the box in which the new cartridge arrived. See the enclosed recycling guide for recycling instructions.
11. If a non-HP print cartridge is in the printer, check the printer control panel for further instructions.
