Designjet 500 Belt Replacement

The replacement belt arrived fast and was able to follow the steps via the video on their website. The only 2 things to watch out for are when you put the plotter back together again that are not in the video. 1. When putting the service station holder back on, make sure the ribbon cable is not sandwiched behind it before screwing the parts together and 2. put the right hand trim back on the front before putting the right hand cover onto the plotter.


great product and documentation, had no problem installing and now the machine is back up and running. thank you!


knocked down one star since the USB drive was corrupt. But I got quick response from you and e-mailed the PDF.

Great product, great service

Your were a savier. Bought this Designjet 500 printer for 200$ knowing that we needed the strap and other items for it. What you offered was exactly what we needed to get this printer going, in a few steps. Just great! Thanks

Glad I decided to buy the kit!

Not gonna lie I already had one of the cheap china belts ordered and when I was looking up instructions how to install it I found your video on YouTube. It convinced me pretty fast that my cheap belt will end up in more hassle than benefit. I love my printer and I thought spending way more but save the trouble later is a good choice. When Bob said in the video that the belt will last a lifetimeI was completely convinced.

The belt is propably the best you can get, didn't found anything compareable and I'm sure it wont crumble into nothing like the originial. It feels very worth its price since the belt will now propably outlast the printer itself.

What makes it even more special is the Tool and Instructions provided. I basically just did what was done in the video (which is way more easy to grasp than HP's instructions), had a couple of coffee breaks and it took me around one and a half hours, taking it very easy and the fact that I propably won't have to do it again in the future feels very good.
