Installation Precautions
❏
When installing the unit, firmly secure four mounting parts at the bottom of the paper roll
supply module to the system side with screws.
❏
Make sure to ground the unit by using the hole for a ground wire on the side of the frame.
(See Figure 3-1 for the position.)
Note:
If the system side where the unit is installed is not flat, that could cause deformation of parts and
malfunction. (It is recommended the difference in level is 0.3 mm {0.012"} or less.)
Handling Precautions
Paper roll supply module
❏
Do not apply excessive pressure to the
paper roll supply module
when opening or closing
it; otherwise, the unit may not open and close properly because of deformation of parts.
❏
Do not touch the light emission or receiving surfaces of the
paper NE detector
; otherwise
you may cause damage from dirt or static electricity.
Printer module
CAUTION:
Since the thermal head area and the motor surface can be hot during and right after
printing, never touch them with your bare hands; allow about 15 minutes for them to
cool.
❏
Since the EU-T432 contains permanent magnets (in the motor) as well as electromagnets,
they should not be used in an environment with excessive dirt, dust, or metallic dust.
❏
Never print without paper installed or with the head away from the
platen
, because the life
of the
thermal head
may be shortened.
❏
Never pull out the paper (forward or backward) with the head down (against the
platen
).
❏
Do not turn off the power during operations, especially during a cutting operation;
otherwise the cutter blade could be exposed, leaving the
platen unit
difficult to open.
❏
Since the head heating elements and the driver IC are very delicate, avoid touching them
with any metal objects such as tweezers or screwdrivers.
❏
Open the
platen unit
only when required.
❏
Never touch the surface of the head heating elements or the driver IC because dirt may stick
to them, affecting the head heating elements or causing damage from static electricity.
❏
Before handling the
thermal head
, use proper body grounding procedures to avoid
damage from static electricity.
