PAPERSIDE SENS
SENSOR AUTOTEST
This is for adjusting output level of Paper Side Sensor.
1. Adjust the output voltage which is shown at OUTPUT LEVEL within the range between 0.35V and 0.45V.
*Attach the right media clamp with aligning the right edge of the media clamp to the Media Guide Line.
Make sure the media clamp is attached correctly.
*As entering the menu, the Carriage automatically moves to the place where the Paper Side Sensor reads the silver tape
of the Media Clamp.
*Adjust the VR(VR1) on the Carriage Board while checking the output voltage shown on the LCD.
* Lower the Pinch Roll Lever.
2. Carry out SENSOR AUTOTEST.
3. Test and adjustment is completed if the result is as follows.
Output voltage: 0.5V or under.
NOISE: 0
Need re-adjustment if the result is out of above.
* In case of NOISE > 0
There is a possibility that the reflection tape is not clean, or having noise due to wrinkle.
Clean up the reflection tape or replace the new one, then do it again from the step one.
In case of Output voltage >0.5V
There is a possibility that the reflection tape is not clean.
Clean up the reflection tape. If there is scratch, replace it with a new one, then do it again from step 1.
Note:
*The voltage value indicates the voltage of 95% of the whole scanned reflection tape is below the displayed voltage.
* NOISE indicates the number of places where 2.5V is detected more than 0.5mm.
The places can be found out by checking the position when the machine beeps.
When is the Paper Side Sensor adjustment necessary? ;
*In case Paper Side Sensor is replaced, or the part which the sensor is attached on is replaced or adjusted.
*In case Carriage Unit is replaced, or VR is rotated.

MEDIA CLAMP CHK
This is to check whether the machine can detect the Media Clamp by reading the label attached on the Media Clamp.
Here is the checking procedure.
1. Before peform checking, comfirm the followings.
* The media is not installed.
* The Pinch Roll Lever is down.
２. Set the Media Clamp(s).
(It can detects max. two Media Clamps at one time)
Make sure that there needs over 20mm space between two Media Clamps if two of them are fixed.
3. Press Enter key to perform Media Clamps Check.
Carriage starts detecting the Media Clamps by Media Clamp Sensosr.
4. The Check is completed with displaying detecting result on LCD.
*Beeps once if it detects Media Clamp(s).
*Beeps twice if it detects no Media Clamp.
If no Media Clamp is detected, check the following points.
*Check whether the magnet is set properly ( check with the polar direction and setting position of the magnet.)
*Check whether the Media Clamp Sensor Board is set at proper position.

SCAN : Aging for Scan Motor.
The Head Carriage runs max. printing width
in Scan direction.
FEED : Aging for Feed Motor.
Grit Roller runs 100mm back and forth.
BOTH : The Head Carriage runs max. printing width
in Scan direction, and at the same time, Grit Roller
runs 100mm back and forth.
CUTTING : The Tool Carriage runs max. printing width
in Scan direction, and at the same time, Grit Roller
runs the half of max. printing width back and forth.
To stop Aging, press [ENTER] key. The Head Carriage
automatically returns to the capping position, and it
returns to theformer menu after the Head is capped.
Make sure not to perform Aging for excessive time when
the head has ink, in order to prevent the head from being
damaged by dried ink. When Aging is performed with ink
filled, it runs while performing the Flushing operation.
No Flushing when ink is not filled.
