check switches (called interlock?) on 'main' side door. (yeah, terrible explaination, i know) the bracket might be bent. also had a bad/broken wire from engine/main board to that switch once on one machine.

Paper feed motor error

Stable OFF is detected for 1 s continuously
after paper feed motor stability.
Poor contact in the

Check the connection of connector YC11 on
the engine PWB and the connector on the
paper feed motor, and the continuity across
the connector terminals. Repair or replace if
necessary.
Defective drive

Check if the rollers and gears rotate

any.

Replace the engine PWB and check for correct

Tech Bulletin 5 talks about this. That same C2500 can mean feed motor problem or something's wrong with cover switches, like the other posters mentioned.

Vikingmita mentioned the big left cover (switches can be accessed behind the back cover), but I've also seen a copier do this from a bad front cover switch (next to the toner). Simulation U038 can show you if the cover switches work, but it only tests the small plastic switches and not the metal ones that cut power.
