Remarks
To ensure drum connection, a drum lock lever is added
inside the front door. To remove the drum from the
machine, the drum release lever must be pulled up to
disconnect the drum connector.
The location of the ink detection board has been changed
from the upper side to the right side of the drum shaft. The
ink type switch (SW901), which was not used (always set
at oil type), has been removed.
To supply ink to the ink roller evenly, the second ink supply
hole (count from the front side) of the drum shaft is
covered with a strip of tape.
To ensure paper separation from the drum, the exit pawl
air pump system is standardized. (The pump system can
optionally be installed on the C211/C212/C213 models.)
The thermal head drive board has been removed. The
function of the board has been moved to the image
processing board and the main board.
The thermal head voltage is directly applied from the
power supply unit. The main board applies signal to the
PSU to supply thermal head voltage only during the master
making process.
