After adjustment of the glue temperature,
the glue temperature thermistor (S56)
detected a temperature lower than 135C
for more than 10 sec.
•

B
The glue level thermistor detected a
temperature higher than 170C for longer
than 10 sec. after the glue had warmed
up.
-or-

Glue Surface Error 1
The surface of the glue in the vat did not
reach the lower limit position. This error
occurred when the glue surface was
detected below the lower limit position 4
times in succession during the glue
replenishment cycle.
•
Glue has clogged in the vat
•
Glue supply defective
•
Glue level thermistor (S58)
defective
SC797-23
B
The glue level thermistor could not
detect the glue surface at the upper limit
position: 1) After glue was detected
above the low limit mark, and 2) After 12
glue packets were supplied, and 3) No
glue had been recently applied.
•
Glue has clogged in the vat
•

Glue Surface Error 2
SC797-24
B
Without a glue vat refill, the glue level
thermistor could not detect the level
of the glue below the upper limit (full)
level, even after the application of
25.42 g of glue.
•
Glue application abnormal (not
applying correctly)
•
Glue level thermistor (S58)
defective
