Imaging drum reach 20,000 (black only) or 5,000 (color), replace the image drum.

Supplies life
The life of the imaging drum depends on the number of black-only or color pages that print jobs
require. Imaging-drum life is also affected each time the device calibrates because calibrating causes the imaging drum to rotate. Imaging-drum life is measured in terms of number of rotations rather than number of pages printed.
The type and length of print jobs also affects drum life. A series of short print jobs uses more drum
life than an equivalent number of pages printed in a single large job. To extend drum life, print
multiple copies of a print job at one time rather than sending the same job to the device multiple times.
The life of a print cartridge depends on the amount of toner that print jobs require. When printing text at 5% coverage, black print cartridges last an average of 5,000 pages and cyan, magenta, and
yellow print cartridges last an average of 2,000 pages. High-capacity cyan, magenta, and yellow print cartridges last an average of 4,000 pages. (A typical business letter has 5% coverage.)

try to clean with special set from HP or otherwise to re-calibrate

Its not the printer it's Adobe

Follow each of these steps until the problem is resolved:

Print a printer self-test by holding the power button down with a pencil and opening and closing the top cover four times.
Check the nozzle self-test pattern in the self-test print out. If one or more of the solid rectangular areas are missing, an electrical contact problem may be present.
Remove and then reinsert the print cartridge(s) into the printer.
Print the document.
If the problem persists, follow the steps listed above for cleaning the print cartridges and print cartridge cradle.
Try printing again. If the problem continues, replace the print cartridges.

HP recommended checks: 1. adequate 120 VAC power supply, 2. Remove Fuser Assembly, wait 5 minutes and then reseat. 3. Reset the printer to Factory Default settings (remember to copy down the IP address, mask and gateway numbers first).

While this may solve the problem, it is much more likely it's time to replace the fuser. Cost is approx $125 if you buy it online. Just do a Google search on HP 2840 fuser.

This link will show you where your fuser is and how to remove and replace it.

In this case, actually it is not the Black toner that got depleted. Here the message being displayed indicate that one of the color Toner supply need to be replaced as it got depleted and currently the printer is printing in Black and white using the Black toner cartridge.

in this case, to troubleshoot these issues please try performing the following and check for the results.

* 1. Check for the level of the toner cartridges:

a) Check from the HP Toolbox application. Here are the steps to be performed from your PC:

* Access the Toolbox software.
* Select the Status tab.
* Select the Device status option.

Here you can check for the supplies status in terms of the % remaining for each toner cartridges.

b) By checking the supplies status from the printer control panel display.

On the printer display when printer is in Ready mode the supplies status can be checked from the supplies level indicator. Each toner cartridge and the Imaging drum level will be indicated by a bar which varies according to the level of the supplies present.

c) Print the supplies status page from the printer.

* On the printer control panel menu, press Menu .
* Use the (Right Arrow) button to select Reports, and then press Enter .
* Use the (Right Arrow) button to select Supplies Status, and then press Enter .

If any of the color toner cartridges and the Imaging drum have a low supply level replace them with genuine HP print cartridges.

The part numbers of the consumables are as follows:

* Black print cartridge - Q3960A
* Cyan print cartridge - Q3971A
* Magenta print cartridge - Q3973A
* Yellow print cartridge - Q3972A
* Imaging Drum - Q3964A

By repalce supplies, it means that you have to replace the other toner cartridges and that it is only going to print black only

Black is used on all prints. Did you pull the tape on the new cartridge?
