X shows the result of the state check of the belt unit surface in the number of errors
(1 to 9). As the number is larger, the state of the belt unit is worse. When an error is
detected at the registration mark sensor L or registration mark sensor R, the number of
errors which occurred at the registration mark sensor L is displayed. (The number of
errors which occurred at the registration mark sensor R is displayed only when no
error is detected at the registration mark sensor L.) When ten or more errors are
detected, “NG: A” is displayed.
*2
YYY and ZZZ indicate the largest width in 2,400 dpi dots among the error noises
detected by the registration mark sensor L and registration mark sensor R
respectively. (1 to 999). When an error noise of which width exceeds 999 is detected,
“L: 999 R: 999” is displayed.
