Well lets start with DISREGARD ALL THE ABOVE BULL in the above brainless clarification request first noted. Here's a little good advice for you from a 14 year veteran printer tech.
Lets start with the cheapest and easiest moving to the more difficult or more expensive. Your problem can be caused by a few differnt things.
Print a configuration page (on the printer menu press check button, scroll to info menu, press check, scroll to print configuration, press check. Once you have the look for the page count on the page.
Try fresh good paper from a sealed ****. If your paper has picked up moisture this will show up as light or uneven print.
Next if the printer is over 100K page count, replace the transfer roller (foam roller inside printer under the toner cartridge). Lets try cleaning it first if your under 100K or to see if it improves at all. Any improvement will verify the transfer roller as bad. Review the photo below as it shows the transfer roller end inside the printer. The screwdriver is showing where the release white clips are (two). Press the tabs and lift the left side. The right will come out of the hole socket on its own but note where the hole on the right is for replacement. Try not handling the roller with your bare hands any more than you must as oil from your hands can cause slight imaging defects if your hands are sweaty or damp.
Using a clean rag (like t-shirt material) dampened (not soaking) with 99% alcohol (not 70%) lets clean the roller. Gently but firmly scrub the talc and paper dust buil-up from the roller. Once you've removed the build up it should return to a dark grey color. Let the 99% alcohol dry (5 minutes or so)and reinstall.
Try printing again. If the problem is solved your done. If not and it has improved, you will need a new transfer roller. They are available on Ebay much cheaper than from a dealer. The part number to search for is RM1-0343. Here's a link to ebay for one at around $20.00 landed.
If the problem is the same, your problem is more than likely a dirty laser scanner lense. You'll need to remove the covers from the printer to accomplish this. The laser scanner can be located under the top cover. It's the larger black box on the top side of the printer. Once the scanner has been located, remove the top cover. DO NOT TOUCH THE MULTI SIDED SPINNING MIRROR TO THE REAR OF THE SCANNER. You will be cleaning the clear lenses and mirror towards the front. You clean this gently with a CLEAN and DRY Q-tip. Use a few Q-tips rather than re-applying a dirty one. Heck they are cheap!
Re-assemble the printer and try printing again. One of the steps above should resolve your issue. I am enclosing a link to a free service manual for your printer to help you through the disassembly and in the rare case that your issue remains.
Hope this helps you a lot more than the first response you receved. If so rate me with a FIXYA!

The problem is that the revolving drum doesn't contact the OPC drum proberly. You have to open the left side off the machine and replace the little white gear on the shaft that drive revolving drum. The gear has "jumped"one step and the revolving drum isn't parallell to the OPC drum. I fixed my 2840 last night it takes some time but now it works perfect.

Yes, you will need to replace the drum unit as well. be sure to shop around so you can get the best price because some people mark up the price for that part. You can check the status of your supplies from the printer itself by pushing the "menu" button the printer and scrolling through until you see something about supplies status then press the check mark button.

HP 1600 is quite a decent little printer, so you shouldn't be dissapointed - if it's working properly, which clearly it's not in this case.
It seems that you have 2 problems here.
Firstly it shouldn't click loudly, so you need to be talking to whoever you bought the printer from.
The smudging - is probably a dirty fuser.
There are laser printer cleaning sheets, that will work quite well, but ideally it needs a little bit of dismantling to get at the fuser to clean the two fuser rollers.
I've seen lots of these with dirty fusers, and a clean with IPA does the trick.
