Your local post office has no way to scan the ESE, since the ESE is considered to be contracted business metered mail.
The initial scan (if any) would be initiated at the USPS Distribution Center, which is often located in a more distant community and/or county. Depending upon how you are mailing your ESEs, that possible initial scan may take several days.
For instance -- if you simply mail your ESEs in one of the USPS "blue boxes" scattered around your community, that ESE will probably not receive its initial scan for a couple days: the USPS delivery driver has no means to scan the ESE, so the ESE may sit in the USPS truck overnight, or inside a USPS bag at your local post office until the following day, at which point that bag of unsorted mail would be picked up for transport to the USPS Distribution Center, for arrival later that day or evening.
In addition, if you mail the ESEs on a weekend (especially a USPS holiday weekend), that initial scan will be delayed for a day or so, since there will be no movement on that ESE until the post office opens again.
If your local post office has a 24 hour self-service kiosk in the lobby, you might consider mailing your ESEs in the mail slots in the lobby -- particularly the "Metered Mail" slot. By using this mail slot, the ESE will be mixed in with other contracted business metered mail, and has a better chance of receiving an initial scan at the USPS Distribution Center later that evening.
If your local post office does not have a 24 hour self-service kiosk in the lobby, try mailing the ESEs inside the post office -- but do NOT hand the ESEs to a USPS counter employee. Many of these USPS counter employees are confused about the ESEs, since it is a single piece of contracted metered mail, and they usually handle contracted meter mail in bulk -- so the counter employee may "set aside" your ESE for a supervisor's attention, rather than simply dropping the ESE into the outgoing mail -- and that "set aside" may be overlooked for quite some time.
Rather than handing the ESE to a counter employee, just drop the ESE into the outgoing letter mail slot inside the post office -- that will avoid any "handling" by your local post office, and the ESE will be sent to the USPS Distribution Center later that day.
Admittedly, using the ESE for eBay mailings can be tricky, and a lot more complicated than eBay had initially suggested (or understood!) at the time that the ESE program had been initiated. And not every post office handles the ESEs in the same manner -- so try a few different methods to find out what works for you.
Good luck!
