Fatal Error - Epson Stylus C87 Service Manual

EPSON Stylus C87/C88/D88

3.2.1 Fatal Error

As the most recent fatal error (fatal error code) is stored in the
C H E C K
P O I N T EEPROM (Address: 0AH), it is possible to check the error by using
the adjustment program.
Check the parts according to the contents of the fatal error, and replace the parts as necessary.

Item
Something is wrong with the CR motor.
Carriage movement speed is abnormal.
Carriage has been locked for a certain period of time due to
external factors.
The number of the carriage reverse rotation has exceeded the
predetermined times due to external factors.
One-pass movement cannot be completed though the CR
motor has been driving longer than the specified time.
Abnormal carriage movement speed is detected during load
positioning control.
It is detected that the carriage has been locked for a certain
period of time during load positioning control.
The cumulative movement distance during the load
positioning control has exceeded the given level
The environment temperature of the transistor that generates
head driving waveform on the Main board is abnormal.
During pre-printing X-Hot detection, the temperature of the
head driver IC has exceeded the given level for more than two
seconds.
During post-printing X-Hot detection, the temperature of the
head driver IC has exceeded the given level for more than two
seconds.
