CONFIDENTIAL
Step
7 Is the measure value correct?
Confirms if the measured detection value is correct,
and prints message as follows depending on the
result:
When the value is correct:
When the value is not correct:
8 Find and set threshold value
Calculates and sets the threshold value for both
cases of with and without paper using the detected
values. The threshold value set is printed as follows:
9 Write threshold value in EEPROM
Prints the following message.
Writes the threshold value in EEPROM when the slip
paper is removed. Confirms whether the value is
written correctly, and prints the following message
depending on the result.
When the value is written correctly:
(** shows threshold value in hexadecimal.)
When the value is written correctly:
10 End special setting mode
Prints the following message and ends special
setting mode. The printer automatically enters
printing mode when special setting mode is
finished.
Note:
During the special setting mode, the printer checks several times that DIP switch 2-6 is off. If the
switch is on, the printer prints the following message and ends special setting mode.
5-82 Disassembly, Assembly, and Adjustments
Printer Operation
(6) The measured value is available.
(6) The measured value is NOT AVAILABLE.
Special setting mode is finished.
(7) Threshold value : [ ** ]
(** shows threshold value in hexadecimal.)
(8) Please REMOVE paper
for writing value into the EEPROM
(9) Writing is completed.
Threshold value : [ ** ]
(9) EEPROM Write ERROR!!
EEPROM process STOP.
Please turn ON DIP SW 2-6.
Special setting mode is finished.
EEPROM is write-protected!!
Special setting mode is finished.
User Operation
There might have been some mistakes of user
operation. Go to step 1 and execute the
adjustment again. Replace the detector-slip
insertion assembly if this error message is still printed
after executing the adjustment two times.
Remove the slip paper from the printer
This is an unrecoverable error. Reset the printer and
confirm if the initialization is executed correctly.
Replace the main circuit board if this error message
is still printed after executing the adjustment a
couple of times.
Set DIP switch 6 of the switch bank 2 to off after the
message is printed.
