9-2 (E) Chapter 9 Operational Problems
There are a number of messages which may appear on the monitor screen during
operation. (A message also appears in the time counter display.)
These alarm messages indicate misoperations or problems with the unit such as
condensation on the drum.
To display these messages on the monitor screen, the monitor must be connected to
the VIDEO 2 (SUPER) OUTPUT connector, and the CHARACTER switch on the
subsidiary control panel must be in the ON position. It is possible to disable the
display of warning indications in the menu system, by setting the ALARM and
REF. ALARM items to OFF.
For details of the menu settings see the section "Menu Operations" (page 7-8(E)).
If an alarm message is indicated, take appropriate action according to its contents.
