I'm having lots of problems with my HP Laserjet 2840 since loading it onto my new iMac. Most recent problem is an error message -- "page too complex to print." I'm prompted to press enter, which cancels the job. I've uninstalled and re-installed the driver/software twice, and while I have fewer problems now, the printer is still not working! Never had a problem on my PC.
It might be a case of the printer software you have may not be compatible with the version of the operating system on your new iMac. Check http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00341096/c00341096.pdf for information.

Imaging drum reach 20,000 (black only) or 5,000 (color), replace the image drum.
Supplies life The life of the imaging drum depends on the number of black-only or color pages that print jobs require. Imaging-drum life is also affected each time the device calibrates because calibrating causes the imaging drum to rotate. Imaging-drum life is measured in terms of number of rotations rather than number of pages printed. The type and length of print jobs also affects drum life. A series of short print jobs uses more drum life than an equivalent number of pages printed in a single large job. To extend drum life, print multiple copies of a print job at one time rather than sending the same job to the device multiple times. The life of a print cartridge depends on the amount of toner that print jobs require. When printing text at 5% coverage, black print cartridges last an average of 5,000 pages and cyan, magenta, and yellow print cartridges last an average of 2,000 pages. High-capacity cyan, magenta, and yellow print cartridges last an average of 4,000 pages. (A typical business letter has 5% coverage.)
Looks like you have a corrupt print file. Delete all of your printer documents in the queue, shut off the printer and unplug the ethernet connection and the printer (from the wall jack) for about 30 seconds. Plug everything back in and try again.
Note: If this happens again, narrow down the specific file that's causing it and don't print with it. I've seen webpage PDF's cause this problem in a number of HP's.
Did the noise start right after you replaced a toner? If so it must be a bad toner which is causing the gears to grind. If this noise happened out of the blue then it might be a bad fuser drive gear which is the gears that connect the fuser to the machine.
The HP2840 is a sigle sided scan device. To copy both sides you must copy one side then load the one sided copies in the tray again and repeat the process again. Pay close attention to which side is printed on and scanned on both the original and copies. Also the top to bottom feed order of the auto doc feeder and paper tray. It's easy to get them out of order and copy first page onto last or worse, both sides onto one side of the copy.
The HP2840 isn't capable of scanning both sides and printing both sides at once.
Hope that helps you. If so hit me with a FIXYA. If not hit my user name and further describe the problem to me so I can help you further.
