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.

HP Laserjet 2840 asked for drum replacment afther only 5300 pages but should make 20000. Prits where still perfect but now it refuses to print. Any solutions how to keep using the drum?


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.

Toner specks along the edge of the page


Rev. Gregory.
Its looks like you have a small pinhole, or divot, on a imaging conponent that is common to all four toner cartridges. Remove the drum unit from the prtr and keeping the green handle close to you pull back the shutter which covers the drum, and look for spots of toner at the either end. If you hold the page with the spots on it, with the leading edge centered and touching the drum, it will give you some idea where the edgeis relative to the end of the drum. If you can't see any corresponding spots on the drum surface.
Put the drum unit back into the prtr and allow the prtr to restart, then switch off and remove drum, this will have turned the drum to a new position, and should show any defects. Only expose the uncovered drum to light for a minute at a time, and avoid touching the surface.
Let me know what you find.
Cheers

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.

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.
