HP 2840, black ink drum q3964a

HP 2840 printer ran out of black ink. I put this drum q3964a in it. The printer tells my black ink level is normal, "replace black ink" is the message I get on the display. The printer does not work with this brand new drum. Yet nothing seems to be wrong. What can I do?

Hello, these printers tend to be finicky.

In other words, just replace the black toner. When the printer says its low, or empty, regardless of wether or not it is, just replace it.

Replacing the drum, when it says black toner needs to be replaced will do nothing to rectify the issue.

Buy only HP Toner and Drum cartridges for this printer. Do not try to refill toner cartridges, and do not reset drum. You will only end up destroying your printer in the process.

MY HP LaserJet 2840 has a brand new Toner cartridge. Now it won't print at all and we are getting a "OPC at end of life" prompt. What does this mean?


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.)

We have an HP Color Laserjet 2840 printer in our office. We were low on our black ink drum, bought a new drum and installed it. Copies are coming out perfectly but the "replace black...


The 2840 is a slightly different sort of machine when it comes to supplies. There is a main imaging drum unit which works for all four colors, and then there of course are the 4 colors. If the unit was asking for a drum unit then you should have instaled a Q3964A. It is entirely possible that your drum unit and black cartridge both expired at the same time, in which case, you need a black toner cartridge now.

The drum is located in front of the ink cartridges and has a handle that you pull up and out of the printer.

Replaced black toner..now printer won't print any


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

DRUM Q3964A FOR HP 2840



10.000x Supply error Description E-label can’t be read or print cartridge is not properly installed. Solution
  1. Reinstall print cartridge.
  2. Power cycle device.
  3. If the problem is not solved, replace the cartridge. NOTE: The software CD-ROM that came with the HP Color LaserJet 2820/2830/2840 all-one includes an animated tutorial that shows how to replace the print cartridges.
    1. Remove any media from the ADF, and then push the scanner-release button to open the scanner assembly.
    2. Open the cartridge door.
    3. Make sure that the correct print-cartridge slot is in the access position.
      • If the correct print-cartridge slot is not in the access position, close the top cover and the scanner assembly, and then press ROTATE CAROUSEL until the correct print-cartridge slot is in the correct position. Pinch together the two large blue tabs on the first cartridge, and then lift the cartridge straight up to remove it from the carousel.
    4. Remove the new print cartridge from its packaging, remove the orange cover from the print cartridge, and then pull the orange tab straight out to remove the sealing tape.
    5. Squeeze the blue release levers on the print cartridge, holding it with the roller facing you. Lower the cartridge straight down into the carousel until it is firmly in place.
      • To replace another cartridge, close the top cover and the scanner assembly, press ROTATE CAROUSEL , and then repeat the previous steps. NOTE: If a black print cartridge was replaced, then the device prompts to have a cleaning page ran, unless the device page count is less than 100 pages.
    6. Close the top cover, and then close the scanner assembly.

HP 2840 is printing light even after putting in a new cartridge


no, that is not the drum, it has a chip on each toner cartridge that send information back to the printers main computer, and that tells the machine how much is remaining.

Has the cartridges been refilled ? need to know before i move unto the answer.

For Flexer and Guest - The Imaging Drum Assy is the 5-th consumable for your printer. U can buy it as well as any toner cartridge. U can find it in the front of the 4 toner carousel with a green plastic cover. Push it to the back of the printer and pull it out straight up. The new one has orange stripes and plastics that you should remove. The Imaging Drum's life is about 20k pages (black with 5% coverage) and 5k page (colour 15% coverage)
