You must turn on error management to have the machine display error codes, otherwise it will just say "CHECK PRINTER".
To turn error management on, enter the following: Press Data registration, #, Set, 00000011, set, stop. Now after the "check printer" message there should be one of the error codes above.
Supposedly, Nation-Wide Repair Service fixes the bad power supplies for $45.00. They can be reached at 800-798-1814. You can also buy one for $148.00 from www.loyal.net I hear. The proper replacement power supply part number for both the LC7000 and LC7500 is HH3-5278 so I am told.
If there is an error code with the 'check printer' then this would be more helpful. If the error code is ~ #323 then you have a laser unit fault- if it is #322 then you have a fuser unit issue. Both units are replaced as a unit.

An internal mechanism is faulty.
1) Check the connection between the laser scanner unit (J802) and SCNT board (J6).
2) Replace the laser scanner unit.
3) Replace the SCNT board.
