Conditions
An error occurred in the carriage encoder signal.
An error occurred in the line feed signal.
An error occurred in the purge unit.
This error takes place when feeding paper from the ASF after an
error occurred in the ASF cam sensor.
The internal temperature is not proper.
The waste ink absorber is full.
The print head temperature exceeded the specified value.
A problem occurred in writing to the EEPROM.
The carriage did not move up or down properly.
An error occurred in the AP motor during purging operation.
An error occurred in the paper feed motor.
An error occurred in the paper feed cam sensor during paper
feeding from the front paper feed cassette.
This error is also indicated when the waste ink counter is 60% or
more, and a paper jam occurs in the under guide.
The USB Host VBUS is overloaded.
An error occurred in the valve sensor during cleaning.
The AD conversion value indicating the motor driver temperature is
not proper.
None of the ink tank position is detected.
The PCI bus error is detected by the ASIC.
The scanner unit cannot detect the home position at power-on.
Because it is assumed that the machine was powered with the lock
lever locked, although this error is classified as the service call
error, this error is indicated by both Alarm LED (orange) and the
LCD message as in an operator call error.
On the LCD, "Release the scanner lock switch and turn off the
machine and then on." is displayed.
The scanner unit cannot detect the home position, or the scanner
unit warming-up is not done properly at power-on.
On the LCD, "Scanner is not operating correctly." is displayed.
The check sum value is incorrect in the ROM check at hard-power-
on.
1-6
An ink tank which has once been empty is installed. Replace the
applicable ink tank with a new one.
If continuing printing, the print head may be damaged.
When continuing printing using the ink tank in which ink was refilled,
press the Reset button for more than five seconds to leave the history
which shows that the ink tank in which ink had been refilled was used.
* After this operation, the ink remaining detection function is released.
A non-supported ink tank is installed (the ink tank LED is turned off).
Install the supported ink tanks.
An error occurred in an ink tank (the ink tank LED is turned off).
Replace the ink tank(s).
Close the scanning unit (access cover).
