2. LIST OF ERROR DISPLAY / TROUBLESHOOTING

Errors and warnings are displayed by the following ways:

1. Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution are displayed on the LCD in text and by icon.

2. Messages during printing from a computer are displayed on the MP driver Status Monitor.

3. Error codes (the latest 10 error codes at the maximum) are printed in the "operator call/service call error record" area in EEPROM information print

Buttons valid when an operator call error occurs:

1. ON button: To turn the machine off and on again.

2. OK button: To clear and recover from an error. In some operator call errors, the error will automatically be cleared when the cause of the error is eliminated, and pressing the OK button may not be necessary.

3. Stop button: To cancel the job at error occurrence, and to clear the error.

Solution

Confirm that the rear tray is selected as the paper source. Set the paper in the rear tray, and press the OK button.

Confirm that the cassette is selected as the paper source. Set the paper in the cassette, and press the OK button.

Remove the jammed paper or foreign material causing a paper jam (paper remainings, clips, pens, etc.), and press the OK button.

Replace the applicable ink tank, or press the OK button to clear the error without ink tank replacement. When the error is cleared by pressing the OK button, ink may run out during printing.

An ink tank which has once been empty is installed. Replace the applicable ink tank with a new one. Printing with a once-empty ink tank can damage the machine. To continue printing without replacing the ink tank(s), press the Stop button for 5 sec. or longer to disable the function to detect the remaining ink amount. After the operation, it is recorded in the machine EEPROM that the function to detect the remaining ink amount was disabled.
