HP LaserJet 2840 replace drum

Will not print or copy.  Error Message  "replace drum".  Took drum out and went to cartridge world.  The drum worked in their HP printer.  It still did not work in mine when I put it back in. I replaced black ink cartridge thinking that was a more likely problem. No change. The machine is in my home and we are not heavy users.  RM

Have you checked status for the drum using toolbox or solution center? Try clean the contacts on drum and opposite HV pins in printer.

How to reset supplies on HP 2840 laserjet?


"Would like report of supplies from 2840 laserjet. How to get it to show report"

Select 'Menu" button, then select "Reports", then select "Supplies Report".

This will print the status of the four toner cartridges and the drum.

It doesn't make sense to reset toner cartridges UNLESS you refill them
first. On the HP 2840 each cartridge/drum contains a chip that measures
the life of the unit.

You can purchase toner/chip combinations online cheaper than new
cartridges. I also purchase drum chips to extend the use of my drum
until print quality actually starts to deteriorate.

I use both of these methods to save money on supplies - buy toner and
toner chips, buy drum chip to get full use of drum unit.

Hope this helps.

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.

This means that the printer cannot read the E-Label on the cartridge, or it is not properly installed.

  1. Reinstalle the cartridge
  2. Power cycle the device
  3. If the problem is not solved, replace the cartridge. (Is the cartridge a remanufactured one? this can be a problem)
  4. Check if correct cartridge type.

The fuser is the heating unit near the paper exit, and that error means the lamp is burned out, the overtemp sensor is out, or the thermistor in the fuser is bad. About all you can do is replace the fuser. www.precisionroller.com will have a new fuser for you.

The HP Color Laserjet 2840 Is a Very Good Reliable Printer. I'm curious if you are buying American made components or cheap components from some thrid world country sold at ahuge retailer. They really should stand behind their laser drums, but if they don't then shop over at www.officeinks.com or www.wowsuperdeal.com and Purchase American Made Toner Cartridges and Laser Drums. Office Inks has a 1 year satisfaction and quality guarantee and free return shipping if their ink, toner, drums, ribbons etc, don't make you happy. Only Ships USA Though.

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.

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.
