Cautions regarding automatic print adjustment
Notes
The printer cannot set a correct media advance adjustment value through automatic print adjustment in the following
cases. In such cases, improve the conditions or perform manual print adjustment.
The automatic print adjustment determines mechanically the media advance adjustment value, so absolute precision of
the setting cannot be guaranteed.
- The media used makes the check via sensors impossible.
(Some media types, even conventional ones, may not be supported by automatic print adjustment.)
<Examples>
- Transparent or colored media
- Media with a rough surface
- Media with an extremely high or low degree of reection
- Media on which the pattern cannot be printed properly, such as when the ink tends to bleed
- The media surface is soiled with dust, ink, nger marks, etc.
- A gap tends to form between the platen and the media
- Lots of nozzles are clogged
- The media heater temperatures are not suitable
- The environmental luminosity is too strong
With automatic print adjustment, the printed pattern is read automatically to determine the media advance adjustment
value. However, discrepancies may appear in the printed pattern between media lots or if the media is old. Therefore, the
detection results may be incorrect even when using the same media.
In such cases, use manual print adjustment.
When automatic print adjustment cannot be performed
Automatic adjustment is not possible if one of the following messages appears when automatic print adjustment is
performed.
In such a case, perform manual adjustment or check the items and perform the measures described below.
MANUALLY ADJUST 1
ADV VAL/PRINT POS
Meaning
The amount of light received by the sensors did not reach the reference
level.
Items to be checked Corrective measures
Check that the sensors for
automatic print adjustment are
not covered with ink mist.
Clean the sensors for automatic print adjustment.
(See Cleaning around the ionizers and the sensors
for automatic print adjustment on
page 139.)
Check that the media is clean. Feed the media until you reach a clean section.
Check that the media is not
wrinkled.
Reinstall the media or feed the media until you reach
a section without wrinkles.
Check that you are not using a
media type with a light reflection
rate too low.
Automatic print adjustment may not be possible
with some media types. In such a case, use manual
print adjustment.
MANUALLY ADJUST 2
ADV VAL/PRINT POS
Meaning
The amount of light received by the sensors exceeds the reference level.
Items to be checked Corrective measures
Check that the media is not
wrinkled.
Reinstall the media or feed the media until you reach
a section without wrinkles.
Check that no external light
reaches the sensors.
Block the external light or change the printer
installation location.
Check that you are not using a
media type with a light reflection
rate too high.
Automatic print adjustment may not be possible
with some media types. In such a case, use manual
print adjustment.
