I am using a ZKTeco Time Attendance Terminal with these details:

Model: K50-A
Platform: JZ4725_TFT
Firmware: Ver 6.60 May 25 2018
FP Algorithm: 10

I can perform almost all operations found in the demo application, except the online enrolling. Whenever I try to enroll fingerprints to a user, the device just blinks an this error shows up in the application status: 

Enroll finger failed. Result=6

From what I found for the GetLastError() method in the SDK doc, it probably means, Wrong Password. But I have already connected with the device with commKey and all other operations are working.

What error is it? How can I fix it?

Share the program you used for connecting the device, and SDK call used for enrolling fingerprint in the comment to have a better understanding. Anyway, your issue looks like firmware issue. You have to get your vendor to give you the updated firmware as per your mother board version (ZKMxxx/ZLMxxx). The bad thing is, your vendor might not have this knowledge to understand at SDK level. So, all the best.
