"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.

Did you purchase a new OEM HP toner or a refilled or remanufactured toner. It is possible that the chip is bad on the cartridge in which case if it is a true HP cartridge have them replace it. If you purchased 3rd party go after the vendor to replace it.

Thank you for contacting FixYa with your printer inquiry.
The low ink could definitely be the problem thats prompting the error. To begin troubleshooting print the supply status page and confirm the state of the various supplies. Follow the steps below:
Supplies Status page The Supplies Status page lists the remaining life of the HP print cartridges and the HP imaging drums. It also lists the estimated pages remaining, number of pages printed, and other supplies information. You can print a Supplies Status page from the device or the HP Toolbox. To print from the device, complete the following steps. 1. On the control panel menu, press MENU. 2. Use the button to select Reports, and then press ENTER 3. Use the button to select Supplies Status, and then press ENTER. Note Supplies information is also available through the HP Toolbox.
This page illustrates conditions of consumables for Toner Cartridges, Image Drums, Image Transfer Kits, and Fuser Kits. It also provides ordering information and methods for disposing of or recycling used supplies.
Supplies information is also available through the HP Toolbox.
Areas of Supply Status Page: 1. Print-cartridge area. This area contains a section for each of the print cartridges and provides information about HP print cartridges. This information includes the part number for each print cartridge, whether each print cartridge is low, and the life remaining for each print cartridge expressed as a percentage, as a graphic, and as the estimated number of pages remaining. This information might not be provided for non- HP supplies. In some cases, if a non-HP supply is installed, an alert message appears instead. 2. Imaging-drum area. This area contains the same information for the imaging drum that the print-cartridge area provides for the print cartridges. 3. Warranty Note. This section contains information about how the device warranty is affected when you use non-HP supplies. It also requests that you call the HP fraud hotline if a supply that is being detected as a non-HP supply was sold to you as a genuine HP supply. (See HP fraud hotline.) 4. Ordering Information. This section contains basic information about how to order new HP supplies. See Checking status and ordering supplies. 5. Recycling Information. This section contains a link to the website that you can visit for information about recycling. See Replacing and recycling supplies.

Hi

No print on the left side indicates that the toner powder on the left side is almost empty. Try to remove the toner cartridge and shake it well if the toner are new.

If still the same, you need to replace new toner cartridge to get better print out.

Please rate and make a comment if you find this solution very helpful and might help others as well. Post more comments if you need more help.

Regards and thank you for using Fixya !

Check online for refill instructions and where to buy the chip to replace on the drum, most of the drums today have little chips to replace that tell the printer when they are used up, even when there's still life in them.

dear sir good day you can do that by chose to not print much more document and if you do that you can chose to print in economic printing ... thats can reduce 50 % from the usage thank you

Did you remove the sealing tape?

5. 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.

6. 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.

7. If you need to replace another cartridge, close the top cover and the scanner assembly, press ROTATE CAROUSEL, and then repeat steps 4 through 6.

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.
