I have a HP 4500 officejet printer that makes a load clicking/knocking noise before printing and when i turn the machine on.
It also seems to be accumulating excess ink under the print cartridges.

When I turn on my hp Officejet 4500 printer the carrage makes a very loud clicking or klunking noise as it seems to bounce against the end of its run for several seconds. It will pause for a few seconds then start klunking again for a few seconds. Somthing is going to wear out soon! This is a new problem for a printer that has worked well for several months. I tried all the downloadable trouble shooting software packages and nothing was detected.

Loud clicking on my HP C4680 (4 yrs old) each time I print a page. Print fine. Started this week. HP diagnostic tool software didn't help. Moving cartridges left and right on carriage no help. Printer dying...?

I have the same problem and have stripped my printer. The fault you describe is caused by the teeth on the right hand side of the scanner linear bar being worn away.
If you open up the scanner lid before you switch on the printer, so that the teeth on the linear bar are visible to you, now switch on printer and watch the scanner mechanism travel from left to right. It will move quietly and smoothly till it reaches the right hand side of the toothed bar. Once it reaches the right hand end of the bar the scanner mech. will begin to judder and the sound you describe will be emitted.
The bar is cast into the plastic inner lid and cannot be replaced but the good news(?) is that the two white cogs that engage with the toothed bar and are driven by a small electric motor, are quite hard and show no visible signs of wear.
Repairable - well if you are prepared to spend the money and buy, if you can buy, a new inner lid and then have someone fit it for you so be it but I would think the cheapest and easiest option would be to buy a new printer. I will be doing just that but it won't be another HP. I don't think I have fed a ream of paper through this rubbish product befor the fault became apparent.
