I am not completely clear on your question, but I can tell you that Biometrics (fingerprinting) occurs near the beginning of the process - about a month to six weeks after filing. The complete I-751 Petition to Remove Condition process can take eight to eleven months; it is one of the slower USCIS processes.
So, if a long time passes after fingerprinting without your hearing anything, it doesn't necessarily mean anything is wrong.
In an application to remove the conditional nature of a "Green Card," one step includes completing a biometrics/fingerprint appointment. The USCIS then has discretionary authority to require an interview.
In the event of an undue delay, an attorney who belongs to the American Immigration Lawyers Association (AILA) may use USCIS-AILA Liaison channels to find out information or prod the USCIS to take action.
