A former worker at Memorial Sloan-Kettering stole nearly $4 million from the cancer center in a massive scheme that involved ordering a boatload of unnecessary printer cartridges and reselling them, authorities said.

The loot from the elaborate scam was used to fund a lavish lifestyle that allowed $37,000-a-year receiving clerk Marque Gumbs to move from a Bronx housing project to a luxurious Trump high-rise in the suburbs.

Gumbs, 32 — who was arraigned yesterday in Manhattan Criminal Court on charges of grand larceny and criminal possession of stolen property — allegedly began his scheme in 2004 by ordering extra toner cartridges and reselling them.

In one astounding stretch from October 2009 through August 2010, Gumbs ordered $1.2 million worth of toner that wasn’t usable for any machine at the hospital, authorities said.

His alleged ruse cost the hospital $3.8 million.

Gumbs, who first started working for Sloan in 1999, instructed delivery drivers to call him when they were close to the East 53rd Street site where he worked so he could personally receive the packages, officials said.

Sources said Gumbs was caught on surveillance video taking the parcels — which never went through the mailroom — to a garbage area.

Investigators are still working to determine who allegedly bought the goods from the suspect and how much he was allegedly paid.

Records show Gumbs lived in the Murphy Houses in The Bronx before he started his alleged swindle. Last year, he moved into a 30th-floor apartment in the swanky Trump Plaza in downtown New Rochelle.

Gumbs was fired Tuesday, said hospital spokeswoman Kathy Lewis, who, citing the ongoing investigation, declined further comment.
