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.
Sounds like you have the paper size in the tray set incorrectly. For example, it may be set to legal, but you have letter size in the tray. This would cause that message to display. Check your setup options for the paper setting.
You could try cleaning the one on there, but all brothers similar to yours are plagued by this problem.
To clean it try:
SWITCH MACHINE ON WHILST HOLDING DOWN MENU/SET KEY, THIS PUTS MACHINE INTO FACTORY SETTINGS MODE. (MAINTENANCE WILL SHOW ON LCD) ENTER CODE:84 & WAIT WHILE MACHINE PERFORMS A FORCED CLEANING CYCLE. (cLEANING WILL SHOW ON DISPLAY) NOW ENTER CODE:09 & MACHINE WILL PRINT OUT ITS PRINT QUALITY CHECK SHEET. (IGNORE INSTRUCTIONS PRINTED ON CHECK SHEET) CHECK QUALITY & REPEAT BY USING CODE:84 IF NEEDED. (YOU MAY HAVE TO DO THIS SEVERAL TIMES BUT YOU SHOULD SEE A STEADY IMPROVEMENT WITH EACH CLEANING CYCLE)
WHEN FINISHED AND QUALITY IS GOOD, ENTER CODE:99 TO RETURN TO STANDARD MODE. PRESS MENU/SET 4, THEN MONO FAX START TO PRINT OUT PRINT QUALITY CHECK SHEET & FOLLOW ON SCREEN INSTRUCTIONS.
The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed.

Display goes blank or Maintenence mode is displayed, if not... not quick enough, do again to you get it, then press 77 start, error should display. press 99 to exit Maintence mode, dont play with other numbers!!
