Platen Roller Replacement - SATO /s8408 Operator's Manual

PLATEN ROLLER REPLACEMENT

The printer's platen roller is considered to be a high-wear component due to constant treading of the print media
and ribbon stock against its contact surface. This constant contact will eventually wear grooves into the rubber
material and negatively affect print output. This procedure applies to all three rubber rollers.
Switch off the printer and observe appropriate lockout-tagout procedures.
1.
Remove label media as required.
2.
Loosen screw (1, Figure 6-3) sufficiently to rotate bearing clamp (2) from bearing (3).
3.
NOTE: Figure 6-3 shows screw (1) and bearing clamp (2) as being removed for
display purposes only. It is not necessary to remove those components for roller
replacement.
Withdraw bearing (3) from chassis (4) and worn roller (5).
4.
Withdraw worn roller (5) from the printer and insert replacement roller (5) in its place.
5.
Insert bearing (3) onto the free end of replacement roller (5) to nest against chassis (4).
6.
Rotate bearing clamp (2) onto bearing (3) and secure screw (1).
7.
NOTE: Ensure the platen roller assembly is fully nested in the printer's center frame
when screw (1) is secured.
Repeat steps 3 through 8 as required for other rollers, and restore power.
