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,

SOURCE: error code 070020
From the service manual:
One of the Drop Detection errors has occured - or, during the Drop Detection no drop was detected.
Pen checking is set to OFF.
1. Perform the drop detect calibration
2. Troubleshoot the cartridges and the drop detector
3. If required, replace the service station
4. Check the cable assembly and the main PCA.
If you are inclined, I can upload the service manual for you which tells you how to enter the service mode and perform the drop detect calibration. Warning: If this is done incorrectly, it could render your machine useless so if you are not inclined to do so, hire a professional to do it. Otherwise let me know and I will upload the manual for you.
