(*1): 
·Effective only for the model type with the paper roll supply module
   
·This setting lets the printer tell the paper nearend by sending the secondary paper nearend status when the
     specified length of paper is fed after the primary paper nearend sensor in the paper roll supply module
     detects the paper nearend.
(*2): Effective only when using with the cut sheet presenter module.
Definition of the primary paper nearend and the secondary paper nearend:
  · The primary paper nearend is defined as when the paper nearend sensor in the paper roll supply module detects 
    the paper roll nearend.
  · The secondary paper nearend is defined as when the paper is fed for the specific length after the primary paper 
     nearend is detected.
When the primary and the secondary paper nearends are detected, the status from the printer changes. However, 
printer controls, such as the printing stop are not affected.

(*1): Do not set SW 3 to ON in the following condition:
· The partial cutter is used when the cut sheet presenter module is not used.
When backward paper feeding is enabled, the following process is executed.
· After cutting the paper with a 
GS V command, backward paper feeding is executed. (When the Black 
           mark sensor is disabled.)
· The print starting position adjustment with a 
GS (F command can be set to the backward direction 
   relative to the cutting position. In this case, the maximum backward correction value is 14 mm {0.55}
  (112 step 
´ 0.125 mm {0.005} per step).
(*2): Specific offline means the following states.
  
· Error state except an automatic recovery error state
  
· Platen open
  
· Cut sheet presenter module or cover open
  
· Paper empty
    If this switch is turned on, the printer clears the receive buffer when the offline status shown above occurs. Then 
   the printer executes any real-time command (
DLE ENQ, 
DLE EOT) if it is there, and discards all other data.
   When the receive buffer is cleared, if this switch is turned on, three bytes of data, 37H, 24H, and 00H, are 
   transmitted.

Handling 
Precautions
Transport Precautions
oWhen shipping the printer, use anti-static packing materials.
oRemove a paper roll when transporting the EU-T532/T542.
oMake sure to close the paper roll hold unit
 of the paper roll supply module, the platen unit
 
of the printer module, and the main unit and the upper frame, cut sheet presenter unit
 of 
the cut sheet presenter module when transporting.
Carrying Precautions
oHold the frame, main
 and the holding the plate, printer
 of the paper roll supply module 
when carrying.
Note:
Do not hold parts other than above such as the holder, paper roll
 (or shaft, paper roll
) or the 
roller, paper roll tension
; otherwise the functions may be affected because of damage or 
deformation of parts.
oWhen you put this unit on a place such as a desk, be sure to put it on a flat place; otherwise, 
the unit may fall down or a malfunction may occur because of deformation of parts.

Installation Precautions
oWhen installing the unit, secure firmly four mounting parts at the bottom of the paper roll 
supply module to the system side with screws.
oMake 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
oDo 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.
oDo 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.
o 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.
oNever print without paper installed or with the head away from the platen
, because the life 
of the thermal head
 may be shortened.
oNever pull out the paper (forward or backward) with the head down (against the platen
).
oDo 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.
oSince the head heating elements and the driver IC are very delicate, avoid touching them 
with any metal objects such as tweezers or screwdrivers.
oOpen the platen unit
 only when required. 
oNever 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. 
						

							Rev. AHandling   3-3 EU-T532/T542 Technical Manual
Confidential
oBefore handling the thermal head
, use proper body grounding procedures to avoid 
damage from static electricity.
oMake sure no dust collects on the thermal paper.
oSince the printer uses a line thermal print head, condensation must be avoided. If 
condensation occurs, do not turn on the printer until it has disappeared.
oDo not apply excessive pressure to the thermal head
 connectors. 
oAn FFC can be replaced only ten times; then you must use a new one.
oDo not apply excessive pressure to the lever, platen
 when opening or closing the platen 
unit
 with the lever.
Cut sheet presenter module
CAUTION:
Since the paper feed motor and the solenoid surface can become hot after printing for 
a long period of time, never touch them with your bare hands; allow about 15 minutes 
for them to cool.
oSince the EU-T532/T542 contain permanent magnets as well as electromagnets in the motor 
and the solenoid part, they should not be used in an environment with excessive dirt, dust 
and metallic dust.
oOperate the cut sheet presenter module or the upper frame, cut sheet presenter unit
 only 
when required.
oDo not turn off the power during operations, since that could cause a paper jam.
Control circuit module
Serial interface is secured with inch-type hexagonal lock screws for the default setting. If you use 
millimeter-type screws, replace the inch-type screws with the millimeter-type screws attached to 
the frame, main
 for type 1 and 2. (For type 3 and 4, millimeter-type screws are enclosed in the 
box.)
Paper roll
oUse only the recommended thermal paper because thermal paper contains a high ion 
content such as Na, K and Cl may damage the head heating elements.
oAvoid heat, humidity, sunlight and solvents, regardless of whether or not the paper has 
been used. (Thermal paper gradually darkens at about 70°C {158°F}.)
oRemove the installed paper roll when the unit is not used for a long time in a high 
temperature, or high humidity condition; otherwise the thermal sensitive materials 
contained in the thermal paper may stick to the thermal head area, affecting the printing 
quality.
oLabel sheets are not available for the EU-T532/T542.

Storage Precautions
oDo not store the printer in environments with excessive dust, high temperature, high 
humidity, or in direct sunlight.
oBefore storing the EU-T532/T542 for an extended time, remove the paper and wipe off dirt 
and dust; then clean parts such as the platen
 and the thermal head
 of the printer module, 
rollers of the cut sheet presenter module with alcohol. After the alcohol evaporates, close 
each module and store the unit. 
Note:
If you leave the printer with the paper installed, discoloration of the paper and stickiness between the 
paper and the platen
 may occur. In this case, replace the paper.
oStoring the printer for an extended period with the platen
 closed could cause the platen 
rubber to deform and result in defective printing. If the platen rubber is deformed, it can be 
restored to its proper shape by feeding paper through the printer. Just feed paper through 
the printer until the platen
 works properly; then resume printing.
Opening/Closing Units and Modules
Note:
oDo not apply excessive pressure to any operation part; otherwise its function may be damaged because 
of deformation or damage of the part.
oApply pressure to each operation part only in the specified direction; otherwise its function may be 
damaged because of deformation or damage of the part.
