Installation Precautions
When installing the unit, secure firmly 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. (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 hold unit when opening or closing it;
otherwise, the unit may not open/close properly because of deformation of parts.
Do not touch the light emission or receiving surfaces of the paper NE detector, as dirt may
stick to them, or cause damage by static electricity.
Printer module
CAUTION:
Since the thermal head area and the motor surface can become hot right after or
during printing, never touch them with your bare hands; allow about 15 minutes for
them to cool.
Since the EU-T532/T542 contain 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 and the driver IC, as dirt may stick to
them, affecting the head heating elements or causing damage from static electricity.
