SOURCE: HP 2840

the carousel gears are out of sync - "off a tooth" and have to be realigned.  i spent 3 days last week fixing this problem - it's quite a job, to say the least.  my question - if you ever check for this answer - is: what were the circumstances when the problem first occurred?  just after replacing a toner cartridge?  if so, was it recycled cartridge?

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

SOURCE: 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

SOURCE: 2840 only prints on right side

If you are a bit adventurous and a bit patient, you perhaps can fix this yourself, and not require any disassembling. It worked for me on a similar 'carousel' unit... hp2550L.

For extra info, check this post out. http://www . fixyourownprinter . com/forums/laser/40284 (remove spaces)

If you look closely at the spot where a toner cartridge slips into a slot of sorts, you might see left side aligned and right side just a little off of 'good alignment' for that slot. What I did is to pull on the top of the black-plastic gear. Pull it toward the center of the printer.

There is a small, white gear at the very top of the black gear (not easy to see at first). By this pulling and bending of the black-plastic gear, you can get the gear teeth free of the white gear --- for just a moment. Just enough for the gear teeth to free-up and find their proper place. It doesn't take much.

When done, take a breadth and relax. Turn power off/on, and try it out.

My printer won't print---I just had the black ink cartridege refilled but it keeps saying replace supplies


Return the cartridge and use only genuine supplies with HP. HP cartridges have chips on them that dictate if they are OEM or not. Typically, if you use a refiller , these chips won't get reset.

Hp color laserjet 2840 - prints one page in color, next in black & white. Yellow ink cartridge light blinking. Says "replace supply, using black only". Yellow wasn't showing as low previously.


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.

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 "Replace supplies"


If one of the color cartridges runs out the machine will switch to black only mode. However, I have found no way to force it to continue printing in color mode when any one of the cartridges runs out.

Replace Cathridge


The front panel tells you witch toner cartridge should you replace. If a supply memory error ocures then the cartridge should be replaced or exchanged with a new one. The imaging drum unit is also consumable. for "Joe 50" - there are 4 toner cartridges in the printer.
