5: Operation disabled
1: The operation is enabled in a line other than the trouble line.
3: When detected during other than a job, the operation is enabled with a tray other than the trouble tray.
4: When detected during other than a job, the operation is enabled in a section other than the trouble paper exit section. * However, it is valid
only when the escape tray setting has been made.
6: When detected during other than a job, the operation is enabled in the OC mode.
7: When detected in other than a job, the operation is enabled in the OC mode/single surface scan mode.
8: When detected in other than a job, the operation is enabled in other than the duplex color scan mode.
9: When detected during other than a job, the operation is enabled in the black and white mode.
*10: Since communication is enabled, reception can be transferred. (Noted in the list print category of the system setting screen operation
because it is an operation on the system setting screen.)
11: When detected during other than a job, the operation is enabled in other than the DESK and the LCC.
*12: Trouble display message is displayed in 2 lines. (Example: Ready to copy. F2 trouble)
*13: When FIERY (EFI) option is installed, PCL will not operate. (Machine specifications) (Exclusive)
*14: Only FIERY (EFI) option list print (self print) is disabled.
15: When in U2-22, trouble notification cannot be made. When in U2-23, if either of the FAX soft SW or the FAST data cannot be restored,
the data are initialized, disabling trouble notification.
17: Job execution enable only in a format other than high compression PDF.
*19: When the color mode is set to disable in the "Color mode disable setting" of the system setting, the operation is enabled in the black and
