WARNING!
Disconnect power cord before replacing important parts.
CAUTION:
1. NEVER separate the ribbon motors from the attaching plate (bracket), because doing so will
change their adjustment. (See Fig. 2-8)
2. NEVER remove the two screws painted red on the side of the print block. (See Fig. 2-11)
3. NEVER remove screws unless directed to do so in this manual. Removing screws may change
pre-set adjustments.
1) Turn the power off.
2) Open the right side and top covers.
3) Remove the six screws (FL-4x6, B-4x6 and B-3x8) to detach the left side cover.
4) Remove the (B-4x6) screw to remove the bottom plate.

■ Lubrication
CAUTION:
1. Lubrication: During parts replacement
2. Kinds of oil: FLOIL G-488: 1 Kg can. (Parts No. 19454906001).
3. Do not spray the inside of the printer with lubricants. Unsuitable oil can damage the
mechanism.
All machines are generally delivered in their best condition. Efforts shoud be made to keep them that
way. Lack of oil, or the presence of debris or dust, may cause an unexpected failure. To maintain
in optimal operating condition, periodically clean the machine and apply the proper kinds of oil to each
part in which librication is needed.
Although the frequency of lubrication varies according to how often the machine is used, as a
minimum it is necessary to lubricate before any part becomes dry. It is also necessary to wipe off
excessive oil or it will collect dirt.

4. MECHANISM DESCRIPTION
4.1 CUTTER DRIVE (CUTTER MODE)
The printer supplies DC + 27 V to the cutter motor to rotate it and the clutch counter clockwise. The arm
swings like a pendulum and moves the fixed slide cutter up and down to make a cut.
