Designjet 500 belt replacement video

1. How difficult is it to replace the carriage belt?
If you have average mechanical skills, and the instructions are followed, most people can replace the belt and calibrate the printer without calling for technical assistance. If you have apprehensions about doing the replacement yourself, perhaps you can find another person with technical skills to help you.

2. How long will it take to replace the belt?
An experienced technician can do the work in less than an hour. Allow yourself 2 to 4 hours for the first time.

NASA, JPL, The Goddard Space Center, and many universities buy LPS belt kits. They trust us and you can too.

Best place to get parts for HP design jets


If your plotter carries the bulk of your business, buy the best belt you can to support it. You can also install it yourself with the help of LPS videos.
I have installed three of these and I'm thrilled with the results. With a new belt, oil and some maintenance cleaning my HP Designjet runs like a new one.

DesignJet 500 Plotter Repair Kit

Definitely a solid 4 stars, almost 5.

By including the tools needed, along with bonus cleaner and microfiber cloths, the kit made the process efficient and easy.
The descriptions and pictures were very in depth for the step-by-step installation manual.

My only qualms are as follows:
1. After you take everything apart, the instructions say to follow the steps in reverse order to get everything back together. While this shouldn't be a problem, there are certain steps that need to be approached differently than before to properly install everything (i.e. the tensioning spring). It would have saved time if the steps were detailed out.
2. My only other qualm is with the pictures in the manual. They should be updated in color with real photography. The different belt textures look too similar on certain images and a real picture could clear that up quickly.

All-in-all, I would highly suggest this kit to anyone diving into the task of belt replacement. I found it to be an easy and stress-free process thanks to this kit.

Great Price

Very nice quality is a great purchase
