[1] GENERAL
The AR-121E/151E is the SRU model of the AR-120E/150E.
While the AR-120E/150E employs the drum replacement, the AR-121E/151E employs the developer replacement. Therefore, the display on the opera-
tion panel is changed from “ ” (drum) to “ ” (developer) accordingly.

5) Tilt the DV box unit and rotate the DV18T clockwise to remove
developer.
6) Clean the DV box unit by sucking or blowing with a vacuum cleaner
to remove developer from the MG roller and toner from the DV box
unit. Check that there is no toner or no foreign material attached to
the connector and the gear.
7) Shake the developer bottle 10 times up and down, and remove the
bottle cap and supply developer into the DV box unit.
•Slowly slant the bottle to supply developer evenly.
•Check the label to insure that developer is suitable for the model.
8) Install the THBOX unit.
•Insert two bosses of TH box on the drive side into the positioning
hole of the DV box and fix together.
9) Remove the toner cap, look into the toner supply port and stop the
THD Mylar at the position shown in the figure below. (Rotate the
THK gear on the rear side of the TH box counterclockwise to rotate
the TM shaft.)
10) Shake the toner box 20 times up and down, and remove the bottle
cap and install the refill hose. Check the label to insure that toner
is suitable for the model.
11) Face the toner supply port of the TH box unit upward, and press
and insert the refill hose into the toner supply port with the toner
bottle kept straight up.
•Hold the left side of the TH box with your hand.
•Press and insert the refill hose completely.
12) Lift the toner bottle and shake it left and right and supply toner
until the bottle and the filling hose are empty.
•It takes about one minute to fill toner completely in TH BOX UN
from lifting the toner bottle to emptying the bottle and the hose.
•If toner remains in the hose, when removing the hose from TH
BOX UN, the remaining toner may disperse. Use great care for
that.
13) Check that there is no toner remaining in the bottle and remove
the hose, and slowly pull and remove the hose.
(If there is any toner remaining in the bottle or the hose, perform
toner supply again.)
Bend the refill hose and remove it from the TH box unit without
dispersing toner. Attach the toner cap.
•Attach the toner cap with the toner supply port of the TH box unit
faced upward.
14) Clean the DV box unit with alcohol and attach the DV blade.
•After drying the unit, attach the DV blade.
•After attachment, check that there is no scratch and waves on
the DV blade.
•After attachment, be careful not to damage the DV blade.
•Check that there is no foreign material in the DV blade and the
