It is not recommended that the user replace the carriage belt, on any HP printer. Any damage caused by the user, won't be covered by the warranty and will likely result in a completely useless, but very expensive doorstop. Or paperweight..
I do believe your printer has since been discontinued for support, however only an HP Customer Service Representative would be able to confirm that. I would suggest phoning HP for technical support or to at least confirm whether support is available.
Even if your printer is no longer a) under warranty, which I suspect it's not, or b) out of support completely, they may be able to provide you with a list of Authorized Service Providers (ASPs) within your area.
Best Of Luck.

I recently had this problem as well and it was the service station gunked up with a bunch of ink over the years. Remove the right hand cover of the plotter. Remove the 2 screws that hold the service station in place and slide to the right to remove. When removed, take off the small motor by the gears. The rest is all plastic, I removed the 3 screws and "popped" the two black parts apart and cleaned the spitoon, which is just a sponge. I then dropped the thing into the sink and poured dishwasher soap. Let it sit for about an hour and rinse. It is really really messy. Then put the whole thing back together again. If I recall, the motor was the only electrical component.
Use care and caution so as NOT to break anything and I recall that the only electrical part was the small motor by the gears.
This wasn't so bad and I spent about 8 hours just because I was exercising much caution. If you're more mechanically inclined on the first go, then I would guess about 1 hr to clean and another 1 or two for dry time.
This SOLVED my problem and WOW there was a bunch of ink over the years. Don't worry, that is what the "spitoon" is used for to soak up the excess ink. Well, if not maintained or replaced, then the ink gunks the insides rock hard as in my case.
A new station is about $160 bucks. If you have HP install then you are looking at a few hundred more on top of that. To me, it was worth it and if it didn't work then I just get a new one and I had nothing to lose since the plotter was getting past the 21:10 error.
Be sure to download the HP Service Manual online so you know how to remove the service station. It is just 2 screws. Without the manual, I probably would have taken off many more screws as I would not have thought the service station simply slid out to the right. The designjet is well designed and was glad that I found a service manual online.
Good luck and use caution,

there is nothing easy about this problem. you need torx 8,9,10, and 15 drivers. remove the right cover, remove the service station without breaking it, remove the right frame that holds the service station,release the belt tensioner, remove the encoder strip, remove the display, disconnect the trailing cables, remove the belt, remove the carriage assembly, replace the belt, reverse the process. please be discouraged about this process. this is not an easy repair. if you can find someone someone who is certified on this repair it should take them 60-90 minutes. you can look up the cost of the belt at HP Parts Store. there are only 2 models 24" or 42". my recommendation would be to find an authorized hp dealer. ask them for a quote, the pricing should vary between $300-400. if you can find it cheaper i would be highly suspect and if you've had this printer for awhile then spend the money. make sure they clean and lubricate the rail assembly. good luck!
