The Kent side are languishing in mid-table, although their eight point gap to the relegation zone looks to be enough to keep them up.
United, on the other hand, are six points clear of the chasing pack at the top of League One and will be looking to maintain that advantage with another win at Glanford Park.
"I've told the boys we are going to Scunthorpe United, not Manchester United, and if you are worth your salt then you should enjoy going to play against the top of the league and pitting your wits against the best," said Jepson.
"They are a decent side, out of the top drawer and that is why they are several points clear at the top of the table. It is no accident that they are up there.
"I look forward to going to places like Scunthorpe. You go there and show them what you are all about. You either do that or you go the other way into your shell.
"I don't want my lads doing that, I want them to show what they are about and have a right go.
"They are a very tough, hard working side and are a bit of a throwback to the way northern teams used to be."
