MICR font issues in Check writer (XML) program

 Hi,

We are using check writer (XML) program to print payroll checks. We have designed the custom template and used PrecisionID MICR B font to print MICR line. But the bank (Wells Fargo Bank) is not approving this MICR line. We have used the same font for Payable checks. The same bank approved the payable checks but they are not approving payroll checks. Bank is giving some dimension errors. Half of the MICR line characters tolerance level is less. 

Can anybody help me to resolve these type of issues? Any help greatly appreciated.

Thanks

BMK
