To clear critical "Trouble" codes (e.g., fuser or scanner errors), you must enter the machine's internal .

Open the front cover and toggle the main power switch (located on the bottom left) to the OFF position.

Keep the machine off for at least 60 seconds to allow the internal memory to discharge.

• Each line should contain one tuple of the form '<current state> <current symbol> <new symbol> <direction> <new state>'.
• You can use any number or word for <current state> and <new state>, eg. 10, a, state1. State labels are case-sensitive.
• You can use almost any character for <current symbol> and <new symbol>, or '_' to represent blank (space). Symbols are case-sensitive.
  You can't use ';', '*', '_' or whitespace as symbols.
• <direction> should be 'l', 'r' or '*', denoting 'move left', 'move right' or 'do not move', respectively.
• Anything after a ';' is a comment and is ignored.
• The machine halts when it reaches any state starting with 'halt', eg. halt, halt-accept.

• '*' can be used as a wildcard in <current symbol> or <current state> to match any character or state.
• '*' can be used in <new symbol> or <new state> to mean 'no change'.
• '!' can be used at the end of a line to set a breakpoint, eg '1 a b r 2 !'. The machine will automatically pause after executing this line.
• You can specify the starting position for the head using '*' in the initial input.
