Bob you rock! Still helping people fix their plotters in 2020!!!!!!!! I would like to buy you a beer!

UNbelievable!!! I never would have imagined I could salvage my very elderly and neglected plotter. And there is absolutely no way I would have even tackled it without Bob and my excellent IPS belt. The original was literally hanging on by a thread. I marked every single removed part and referred to this excellent video many times in many places. My plotter’s sweet voice now sounds normal, and the calibration was perfect. I’m so happy! Now if I can just find ink when I need it. These plotters are known workhorses and deserved to be used and kept out of landfills. Thank you, thank you!!!!!

Bought the printer for $100.00 in a garage sale. Replaced belts on a 450 before but reluctant on this one. With the video, instructions and tools provided I was able to complete the belt replacement successfully. Tricky part for me was the encoder strip. I found it easier with another person on the other side pushing the metal tension. Important to clean the brass and plastic belt pulleys.Great video. Thanks!

I would like to thank you so much for providing us with this tutorial, you saved our lives, I'm I Portugal and the belt in our plotter broke about 6 years ago, a time were we were going through a financial disaster in Portugal, we opened our little copy shop, and have struggled for 10 years, the only time until today thank God that we had problems with our plotter, was with the belt, the technicians estimated a total of over 600€ more or less the same as dollars for changing the belt and labour! It was around Christmas time and we used it quait a bit, we had no way to fixed it there was no financial means, so my husband was looking for what the error of the plotter meant,and I came across this lifesaving video, and we took a chance and ordered the parts and we only spent around 70€ and becouse we could not afford to close the store so my husband could fix it, i toke it upon myself to fix it! He was taking care of costumers and i was in the background fixing the plotter, so i would play this video see what you were doing pouse it, and do the same in the plotter, and so it took me a good part of 10 hours to fix it, with play and posing every few seconds I was able to fixed it and it never broke down againg, this is the best piece of equipment that we own, its 12 years old and it works brilliantly!!! So today 12 of June 2020 I was going through old emails and came across the link for this video, and becouse I dint think of doing it before I would like to take this moment and tell you our story and to thank you so very much for your selflessness to take time to make this video, you are a greatest part of our success becouse without the plotter in the month of December we would not have been able to make it, because we print allot of fotos for families to give each other's as Christmas presents, again thank you, thank you so so very much, God bless you and your family we will allways be grateful to you.

Thanks guys! This was my first belt replacement on plotter. The belt on my customers HP500 24" was shedding chunks and part of the belt was just the stringy fibers. 1.5 hours, 15 minutes of which was cleaning rubber out of the motor pulley. I watched the video twice before going to my customer's site and only had to reference the manual twice. Great training!!

Thanks Bob. I bought a used 500 24 inch and was experiencing rattling and lots of noise as the printhead moved left and right. Your video gave me the confidence to take the machine apart and clean the inside of all the sticky gunk that had built up over the years. It works perfectly now. You can read all the tutorials and manuals you like but you can't beat someone who knows what they're doing actually showing you how it's done. Top man!

Thank you so much!

I followed along with this video to replace the 5-year-old belt that had split lengthwise in my hp500. Start to finish took about two hours with the LPS belt in hand, which included about a half hour cleaning a good bit of the belt residue from both pulleys. What impressed me most about the presentation were the little tricks throughout that could not have possibly been conveyed by the most graphic service manual. Without a doubt, much frustration was avoided. Thanks for the attention to detail!

Thank you for putting it back together again, with lots of tips and techniques. This is the most complicated maintenance I've ever performed and this vid made it possible. Thanks so much.

Dear Bob, we are three italian architects.Your tutorial is been very helpful.

Thanks Bob. Nice presentation. Most important part was having the Torx #8 screwdriver. Something you normally only need once or twice in your life. When you have to replace a belt on a Designjet.

Great tutorial on replacing the belt! Very easy to follow - camera work and verbal instruction were spot on! I did discover that I bought a cheap belt ($5) and it had the ribs all the way around the inside but used it anyway. The only thing that I forgot to do was to plug the 'service station' power cable back in. This resulted in a error code after powering up the plotter that indicated the service station needed to be replaced. After plugging the cable in and rebooting, everything was okay. Thanks again for a great video!

As with 2 years ago, again this video has helped me tremendously! We had another one of these plotters called in with a completely chewed up belt. Your video saved me again! (Just wish customers would listen when we tell them where to purchase the belt).

Bought the entire kit even though I had my own tools. I just wanted to get everything I needed in one box for a quick fix.

Great Video Bob! The best step by step video for replacing the belt. I really appreciate the time you took to do the video.

Thanks very much, Bob! The kit was just what we needed, although our "encoder strip" got misaligned when we put it back together the first time. It would not allow for the carriage to "find home." A second try fixed it right up. Thanks for the video and the affordable repair kit!

Great vid Bob!... heres some trivia for you... The media advance calibration should be done on Genuine HP stock AND match the profile selected in the menu. The Cal is actually calculating the amount of rotation, down to just a few minutes of arc, that the platten roller needs move in order to position the TOP surface of the paper to eliminate horizontal banding. It has an LUT in the firmware of media thicknesses for each of the preset profiles. If its done on some random piece of 3rd party media, thats not exactly the same thickness as the selected profile... well it updates the calibration and throws of every other profile thats stored on there. The other option is just to get the end user to calibrate on what they use all the time, selecting the profile they usually use. That way they are sure to get great prints on what they use every day. Hardly anyone actually pays HP prices for their production media on a 500/800 ;)

Excellent video. Instructions are perfect. Not a simple job to take a whole machine apart, but the guidance was great. Take your time you will be successful. I used a pair of long needle-nosed pliers to get that belt tension pully to pop back into place, by squeezing the ends and I possibly avoided breaking the plastic tabs as may happen when prying with a screwdriver.

Just replaced my belt from you and this Video was amazing, just printed out my first 10 blue prints. Thank you for taking the time to put this up.

After watching this video, I purchased the kit as well as an extra belt and installed today.......... VERY easy process and the machine is back up and running smoothly.
