Our printer has been printing unwanted streaks and smudge in red, yellow and blue. It was infrequent at first but now seems to be happening with every document even if the document is just plain b/w text. A few months back I replaced the HP cartridges with some cheaper cartridges I found on the internet and Im wondering if maybe that is the cause of the problem. If anyone has any idea about whats going on here, Id appreciate your feedback. Thanks.

Usually the fault you are describing is caused by the fuser section being left in envelope mode. Open the right hand side door, then lift the grey fuser cover up. Look at the levers on the fuser unit, make sure they aren't pointing at the envelope symbol. If they are, push them upwards. then close everything and try again.
Are you using third party ink? make sure your ink is xerox OEM. This will clogg up the inkjets and ruin the print head for ever, If you have always used the third party ink then you might want to get a new print head. . If you have used xerox ink then It sounds like the magenta reservoir has spilled over the cyan. This is caused by moving the printer and not waiting for the cool down procedure. Also you might want to change the print head wiper. If the print head wiper is over used it won't clean the print head properly and what that causes is for ink to build up and causes smudge. also make sure the drum maintance kit is still in good shape. (its the yellow roller on the right side of the printer. Well hopefully this helps .
Hello sir;The streak line from printing also should be from copy, because the line come from imaging unit, check the meter count if close to or over 50,000 then replace drum and drum blade, it will take care the problem.
The brother printer you need to replace imaging unit( drum unit).
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.
Are you sure this is a Designjet 450 (large format printer) and not a Deskjet 450 (portable printer)? The following assumes you have wispy black streaking on the printed side of the paper. If the streaking is on the back side then post more details of the printer model and the issue.
In either case the most likely cause is a buildup of fibers on the underside of the printheads or carriage, causing wisps of black ink to be dragged on the paper when the carriage reverses direction. You can clean the printer as shown at the following (though the details will be somewhat different for the Designjet or Deskjet....).
