The heaters
The printer includes three heaters for fixing and st
abilizing the printed image on the media. Each heater is
controlled separately.
1. Media roll.
2. Pressure roller.
3. Rear heater (preheats the media).
4. Grid roller.
5. Carriage.
6. Front cover.
ENWW The heaters 195

7. Print heater (fixes the ink on to the media).
8. Front heater (dries the ink and stabilizes the printed image).
WARNING! Do not touch heater surfaces in th e media path. This may cause burns.
Heater temperature settings
Heater temperatures are preset automatically for th e media type that is selected during media loading.
Under normal operating conditions you do  not need to set the temperature.
Use the printer front panel only when you need to  make fine adjustments to the heater temperature.
● On/off setting: use the
SHIFTkey when the heater is selected.
● Heater selection: use the left key or right key to 
select the front (F), print (P) or Rear (R) heater.
● Temperature setting: use the up key or down key 
to set the temperature for the selected heater.
● You can turn the heater ON while the printer 
is not printing by pressing and holding the
OKkey for 2 seconds.
● You can turn the heater OFF while the printer is not printing by pressing and holding the 
CANCEL key
for 2 seconds.
● Front panel display (when the heater is turned on):
●
Upper line: preset temperature for each heater
● Lower line: current temperature for each heater
● Front panel display (when the heater is turned off):
● Upper line: OFF for each heater
● Lower line: current temperature for each heater
A “+” sign indicates that the heater is warming up. Th e default temperature range is set between 15 °C and
55 °C.
Heater preset temperature by medium
The heater preset temperature for  each media type is listed below. Preset the heater temperature according
to the media you use.

We recommend that the front heater, the print heater and the rear heater be set to lower than 50 °C, 45 °
C and 50 °C, respectively.
NOTE When the print heater temperature is set to  high, fixing of the ink on the media is
improved, but media wrinkle or mat print may be caused. Adjust heater temperature according
to the media type and environmental temperature.
When the print heater temperature is set to high, the printer may print at low speed to ensure
stable print quality.
Set the front/rear heater temperature 5 °C hi gher than the print heater temperature. Bad
temperature balance between the front/rear heater and print heater may cause the media to
wrinkle.
Flow of heater temperature setting
1. If you select the media type when loading the me dia, the temperature value applies as follows:
● If the initial temperature value has been set, the heater turns on but heating does not start.
● If the initial temperature value is set to 
**, the heater turns off.
2. If the printing job data are sent from the host (P C), either of the following operations is performed
before the print starts:
a. If the  HEATER PREF  set for the media is  SOFTWARE:
● The temperature set in the RIP (print data, job)
 overwrites the temperature set in the printer,
and the heating starts. Heating does not start if the temperature value is set to  OFF.
● If the temperature is not set in the RIP (print 
data, job), heating starts with the temperature
set in the printer.
b. If the  HEATER PREF  set for the media is  HEAT PANEL:
● The temperature set in the RIP is ignored and heating starts with the temperature set in the
printer.
3. Printing starts when the current temperatures of th e front, print, and rear heaters all reach the value
exceeding set temperature -2 °C.
If the current temperature is higher than the set te mperature, printing starts without waiting for the
temperature to drop. Even after printing has starte d, the temperature control makes sure that the
heaters maintain the set temperature.
4. During printing, the temperature can be adjusted by using the  HEATER key, and then selecting the
rear, front or print heater, and using the 
 or  keys to change the temperature.

Even after printing has finished, the changed temperature is applied as the set temperature.
5. The print job returns to step (2).
To set the initial temperature value of fr ont, print, and rear heaters, and the HEAT PREFsetting (heater),
see the  MEDIA REG  menu.
Temperature control
The following tables describe how heater temperature is controlled.
Maintaining the preset temperature
Function:To heat the media to reduce the ink drying time, improve fixing of ink to media, and to protect
media from wrinkling.
Status:Status of maintaining each heater temperature at the preset temperature.
Conditions: 1.If the heater ON/OFF setting is set to ON and a print command is received.
2. Under condition (1) above, and the time specif ied by the delay time after the print end
command was received.
Maintaining the st andby temperature
Function:To shorten the time needed to reach the preset temperature to start printing.
Status:Status of maintaining the heater temperature at the specified standby temperature (35 °C) for all
heaters.
When the preset temperature is lower than the specified standby temperature (35 °C), the printer
maintains the preset temperature.
Conditions: If the standby time has been set,  after reaching the preset temperature.
Turning off the heaters
Function:To prevent excessive current consumption, to protect the media from damage by the heat from
the heaters, and to protect the user from getting burned from touching the heaters when printing
is not performed.
Status:Status of reaching the environmental temperature slowly.
Conditions: In all cases except when maintaining the preset temperature or the standby temperature.
Start of heating:The print start command is received and heating starts. Printing does not start until the heaters
have reached the preset temperature.
Start of print:The heaters reach the preset temperature and printing starts.
End of print: The print end command is received and printing finishes.
