21 error indicates a problem with the service station. You need to make sure that there is nothing stopping the proper movement of the service station such as a piece of paper. If you do not find anything there, shut the machine off completely and then restart. If the error returns, you will need to run the service station diagnostics, I do not have the procedure in front of me right now but if the error persists, post back a comment and I look it up for you.

    The 21.13 error indicates a problem with the service station, the 86 error should cause the machine to restart and run a disgnostics. the 42 error indicates a problem with the scan axis motor either electrical or overheating. If the carriage out of the lock position, remove the power cord and then try to move the carriage from all the way from left to right. If the carriage moves freely then it is likely that the scan axis motor or the main board is bad. Common issue I have run into is if users open the print head cover and then do not close it properly, allowing the metal latch ring on the carriage to catch on the front of the printer.

Service Station error. Switch the power OFF from the back of the Printer and disconnect the power cord. Check the Primer Tubes. Reconnect the power cord and power On the Printer. Make sure that the Service Station path is clear. Remove any visible obstacles (e.g. screws, plastic parts, etc...) restricting the movement of the Service Station. If the System Error continues, replace the Service Station. If the System Error continues, replace the PrintMech PCA

Designjet T 770 error 47:01

It's a "star wheel motor" error.
Try unplugging power cord from wall.
Plug it back in and power on.
If error persists, a technician is going to have to troubleshoot the printer.
