Anthony Scully marked his return from injury with a goal as the Imps continued pre-season with an impressive win at Salford City.
Players who were not involved trained at the Elite Performance Centre back in Lincoln, and will feature in Tuesday's behind-closed-doors friendly at Stockport County.
The Imps started brightly against the Sky Bet League Two title favourites and won an early penalty when Conor McGrandles was brought down in the area with just three minutes on the clock.
Anthony Scully marked his return with a calm conversion into the bottom left corner past the outstretched hand of Tom King.
It was almost 2-0 moments later when King was at full stretch to tip a Tom Hopper effort wide
The strong start from the Imps continued, with Remy Longdon seeing a shot blocked and Scully effort from distance which stung the palms of King.
Josh Griffiths was not being called upon much in the Imps goal, but got down well to deny Conor McAleny after 13 minutes.
Longdon went close to scoring an absolute wonder goal after 18 minutes. He held off the challenge of Salford's left-back in the corner, before skipping inside past two more defenders and unleashing a shot which saw the ball cannon off both posts before being gratefully collected by King.
The Imps had chances to extend their lead as Tayo Edun led a breakaway down the left, with Ibou Touray just nicking the ball off the toes of the advancing Longdon.
And at the back they were equal to everything the home side sent at them, with Griffiths on hand to tip over a Brandon Thomas-Asante free-kick from a central position and ensure he was not beaten before the interval.
There was one change at the break for either side, with Cohen Bramall coming on in place of Scully as he is eased back to fitness. The home side brought Jordan Turnbull on for Ash Eastham.
Longdon had the opening chance of the second period, going close after collecting Edun's lay-off.
Conor McAleny stabbed an effort ofter after 55 minutes following a cut-back from Tylor Golden.
The best chances of the second half again fell the way of the Imps, with Jackson heading wide from a corner before Hopper doubled the visitors' advantage.
He was left with an easy finish after goalkeeper Zach Jeacock, who had just come off the bench for the home side, lost the ball and the Imps' No.9 had an empty goal which he could not fail to finish from.
The flow of the game was disrupted by a number of changes by the home side, meaning chances were harder to come by.
Regan Poole headed just over from a Edun cross, while Salford's Tom Elliott lifted an effort just over.
