6. When this adjustment is completed, if you need to perform another
adjustment using this program, you can continue without turning off
the printer.
4.1.3 TPE Level Reset
Make this adjustment when the main board or Top PE Sensor has been
replaced. Generally, light level emitted from the photo diode in a photo
sensor lowers with age. For this reason, the printer renews the current
paper remaining level by detecting the black level of the platen each
time the printer is turned on or paper is fed. When the TPE level is reset,
FF is written and it approaches 00 as the time goes by. If this operation
is not performed, paper out condition may be detected despite paper is
set.
1. Perform the pre-operation. (See Section 4.1.1.)
2. Select “TPE Reset” in the main menu screen (Figure 4-4) and press
the Enter key. The screen below appears.
Figure 4-7. Screen - TPE Reset
3. Select “Yes” and press the Enter key. FF is written in EEPROM
when the printer power is turned off.
