Every time now I get this message:

L1 TPS2024B:file: 3574 bytes surplus input "<00><00><00><00><00><00>6<04><00><00>(<00><00><00>@<01><00><00>Ё<00>..."
L1 TPS2024B:file: after 4 bytes: "BM<92>/"


The amount of bytes (3574 in this example) varies from time to time (as I set a different readTimeout), but the second line saying "after 4 bytes: "BM<92>/" remains the same.

Strange...

Looks reasonable.
Please post your results.
You might make the ReadTimeout a little longer since the only negative effect is that it will take a little longer for the transfer to complete.   The postive effect is that the chance of receiving a partial image is reduced.
