HP Laserjet 2840, various problems ' FixYourOwnPrinter

Hello,

The black ink cartridge is cloged or empty. Try to refill it in case of empty, or clean in case of cloged ( left the printhead for 1 hour in clean solution or in hot water if you don't have )

All the best !

You may need to run a clean cycle to see if it will clean the printing drum. Also try removing the toner cartridge and shaking it gently.

You need a new Print Head:
Clean the printhead, then print a test page.

1. On the control panel, press and hold Cancel + Copy/Resume simultaneously until the On/Off light flashes. The On/Off light continues to flash during the cleaning procedure.
2. When the On/Off light glows steady, press and hold Quantity + Cancel simultaneously until the On/Off light flashes, then wait for the test page to print.
3. Review the printed test page and verify that:
• the left color blocks are gray, cyan, and black.
• the right color blocks are magenta, yellow, and black.
• each block is completely filled with color.
• Is the test page blank?
4. 1-800-421-6699,Call Kodak to Report Code BP03

Here is a good solution:

Here is my solution, hope it will solve your problem.

From your post, I believe your CLP-350N printer has enough black toner. The black cartridge is on the far right side of the printer, so the black toner is harder to go to left side of the roller than right side. Everytime we start the printer, it will move some toner of each color to the roller before it shows ready to print.

Because we always use B&W printing when we start the printer, but less Color printing. The result is there are always enough toner on the 3 color rollers, but the black toner is lean on the black roller. When this gets worse, the left side of the black roller may hardly get any toner at all -- so it only print black on the right side fo paper.

Step by step solution
(CAUTION: Never loss balance while tilting printer! You may drop and damage your printer! Hold the printer firmly all the time! Ask someone to help you if needed!)

Here, front of the printer is where you can access the cartridge, back of the printer is where you connect the power cord and USB cable, left is your left, right is your right.

1.Lift the front to keep the printer tilt to its back at about 45 degree
2.Power on printer while it's tilted back, wait untill green light is on
3.Open the front door, red light will be on, then close the door, printer will start up again,wait untill green light is on
4.Repeat step 3 once again, then put the printer back to level position
5.Lift the right to keep the printer tilt to its left at about 45 degree
6.Open the front door, red light will be on, then close the door, printer will start up again, wait untill green light is on
7.Repeat step 6 once again, then put the printer back to level position
8.Print some test page to see if there is any improvement of black print quality.(Hold the printer button for 3-5 seconds, it will print the test page.)

You may try several times and print several pages each time before you finally cure the problem.

Good luck! And do it safely!

All cartridges are new...report shows 0 pages for yellow left yet all others added at the same time show thousands of pages left. Everything printed is in black with no color. BTW: I have 3,000 pages left with black cartridge and the display says I need black.

What should I do?

make sure u have the printing options from printer settings set to black only and not colour..

You just might have a faulty black toner cartridge think back did the problem arise when you installed the new black cartridge. Also is the toner a original if not change for a original.

Hope this Helps
Thanks J

The folded paper solution for for me. Thanks to all for sharing!!!!

I had the same problem. No black or cyan on the left side of the pages. From this advice... I folded a stack of 4 pieces of paper in half and then half again. I took out the transfer unit and put the folded paper in the upper left corner and then put the transfer unit back in. WORKS BEAUTIFULLY! Thanks you all sooooo... much!
