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,

The Trailing Cable has been incorrectly connected OR the fuse in the Electronics Module has been burned.
Corrective Action: Turn the Printer OFF and disconnect the trailing cable. Check that the ends of the Trailing Cable are flat and are not damaged or bent. Reconnect the Trailing Cable correctly, making sure it is pushed in firmly. Do the resistance test. Power ON the Printer and check if the Error Code disappears. If the Error Code continues, replace the Main Logic Board
Note: The logic board is a direct replacement for the Designjet 1050C Plus and 1055CM Plus. If the plotter you are repairing is the Designjet 1050C (not Plus) you will also need to replace the memory and the firmware.
If you are repairing a Designjet 1055CM (not Plus) you will have to replace the Hard Disk Drive also. The firmware is identical for the 1050C Plus and 1055CM Plus
Note: The aerosol fan is not used in the Designjet 1050C Plus or 1055CM Plus. Coil the cable out of the way or completely remove the fan.
WARNING TAKE CARE WHEN CONNECTING THE TRAILING CABLE TO THE ELECTRONICS MODULE OR CARRIAGE. INCORRECT INSTALLATION WILL BURN THE FUSE IN THE ELECTRONICS MODULE, CAUSING THE COMPLETE FAILURE AND REPLACEMENT OF THE LOGIC BOARD. 100 OHMS OR HIGHER MUST BE SEEN AT THE TEST POINTS. CONSULT THE SERVICE MANUAL FOR CORRECT PROCEDURE.
Continuable and Non-Continuable Error Codes
Some of the Error Codes are continuable, which means you can press Enter on the front-panel and continue working with the Printer. Non-Continuable Error Codes do not allow you to continue working with the Printer, in this case power the Printer OFF and ON again and see if the System Error disappears. If the Error Code reappears, then the Printer requires service in order to resolve the problem.
System error codes are hexa-decimal based numbers generally caused by internal system errors. Only try one recommended action at a time and check if the error code has disappeared.
