An Assembly bypoll is due in Bhind next week and the demonstration was part of the familiarisation exercise.
"We have sought a detailed report from district election officer and would come up with a response in the evening," a Commission spokesperson said.
The voters see Voter-verifiable paper audit trail (VVPAT) slip for seven seconds, which would be an acknowledgement receipt for the party they voted for in the election.
According to media reports, the receipt showed the vote going to BJP, irrespective of button pressed, during the demonstration.

Meanwhile, in a hurriedly called press conference in
Bhopal today, Madhya Pradesh Chief Electoral Officer Saleena Singh denied the reports that VVPAT dispensed only BJP slips.
She said her office and the district poll authorities had sent reports on the issue to the Election Commission.
VVPAT-enabled machines would be used at Assembly by-elections at Ater in Bhind district and Bandhavgarh in Umaria district on April 9.
Singh explained that if the VVPAT slip doesn't reflect the voter's choice correctly, he or she can file a declaration, and the election officer will have to follow a set procedure to verify the claim.
If the officer finds the claim to be correct, the voting will be stopped, the CEO said.
"If it is other way round (if the claim is incorrect) the voter will be booked and can face six months' imprisonment or a fine of Rs 1,000 or both after trial (under the Conduct of Election Rules, 1961)," she said.
"Some elements, not mediapersons, twisted the issue," she added.
