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.

My hp 2840 all in one laser jet printer squeaks when it is printing. How do I lubricate my 2840 HP laser jet printer?


Corosol technology is older,slower sounds also too high, it is not suggestible to lubricate the moving parts because of cartrides will move while printing result lot of toner particles raises in printer chamber,if this particles deposited on lubricated area will abstract the moving spares. If you can do the periodical maintenance, use silicon grease for moving parts..

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 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.

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

HP 2840, black ink drum q3964a


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.

HP COLOR LASER JET 2550 SERIES


You will need to replace the image drum. This is either due to the face that you have exceeded the number of pages/cycles that the drum supports or the drum has damage. If this is the drum that came with the printer, it is likely they shipped it with "starter" supplies which last a fraction of the time as the regular "full retail" replacement supplies. A URL for HP's instructions on how to replace tn image drum on the HPCLJ 2550 series follows:
