REPLACE SUPPLIES OUR OFFICE OWNS THIS HP LASER 2840. YESTERDAY IT SAID REPLACE BLACK CARTRIDGE. AFTER DOING SO SAID AND STILL SAYS TO "INSTALL SUPPLIES" ON THE TOP LINE AND RIGHT BELOW IT IT GIVES SHOWS "|?| |?| |?| |?|" WHAT SUPPLIES IS IT TALKING ABOUT? WE NEVER USE COLOR EVEN THOUGH THEY ARE INSTALLED... ANY SUGGESTIONS?

replace supplies shows on screen with 5 sets of hash marks underneth the first set of hash marks from left is black all the way to the top next 2 have 1 line of black at bottom next 2 are empty.will not print copy. replace supplies shows on screen with 5 sets of hash marks underneth the first set of hash marks from left is black all the way to the top next 2 have 1 line of black at bottom next 2 are empty.will not print copy.

My machine says 'Replace supplies" even though it has new cartridges (I only print in Black & whit). I have looked up in the web and others appear to have the same problem. I have attempted all the solutions provided but none seem to work. My printer has the following display

[_] [ ] [ ] [ ] [ ] only the first bar has a black line. My black cartridge is new.

The one solution that had some merit but was for another model is to somehow to overide the 2840 so that the cartridge prints to the end.



It appears to be a common problem that Hp does not want to reslove. If I cant resolve it I will throw it out and go back to brother laser printers



any solutions can be emailed to [email protected]

The cartridge carousel is out of alignment. I just can't figure out how to Re-align it. I have a call in to a technician.

This is a huge problem. I have just replaced the cartridge and yet the HP 2840 shows the same error messages that others have noted here. I took the steps of pulling out the cartridges, powering down, replacing the cartridges, and recalibrating and the "Replace black cartridge" error message showed up again. So it wouln't recalibrate.

Printer was low on color, using black only. We continued using the black only until yesterday it says "Replace Supplies". I replaced all the cartridges and the imagaing drum, couldn't find anything else to replace. Then I restarted. No luck. Then pulled all cords and cartridges out, replaced, turned back on, still the same message. Also did a restore, factory reset. Still says REPLACE SUPPLIES. WHAT SUPPLIES???
