No. Sensor Function Possible problems

1DES sensor Detects paper ejection from the ADF. - Paper jam in the ADF

2DS sensor Detects paper feeding from the ADF. - No paper in the ADF

3ADF cover sensor Detects opening and closing of the

document feeder cover. - Although the document feeder cover is closed, the

machine indicates that the cover is open.

4DF open sensor Detects opening and closing of the ADF. - The machine stays in the sleep mode even when the

document cover is opened.

5SCN open sensor Detects opening and closing of the

scanning unit (cover). - The carriage does not move to the center.

6PE sensor Detects paper feeding and ejection. - No paper

- Paper jam

7ASF sensor Controls paper feeding from the rear

tray. - Paper feed problem

- ASF sensor error

8APP sensor Controls paper feeding and purging

operation. - APP sensor error

9LF encoder sensor Detects rotation of the LF encoder, and

controls its drive. - Uneven printing

- LF position error

10 Carriage encoder

sensor Detects the position of the timing slit

film, and controls printing. - Printing shifts from the correct position.

- Carriage position error

11 Temperature sensor Detects the temperature of the inside of

the machine. - Internal temperature error

12 Ink sensor Detects the position of an ink tank. - No recognition of an ink tank

- Wrong position of an ink tank

13 Valve cam sensor Controls purging operation. - Valve cam sensor error

2. LIST OF ERROR DISPLAY / INDICATION

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.
