Error Codes

As for the causes and countermeasures, only the error codes that are newly incorporated in the unit remedies unique to the product are included in New Error Codes and Recovery Methods. For the causes and countermeasures of other error codes, refer to the separate G3/G4 Facsimile Error Code List (Rev. 2).

Service error code output

When service data #1 SSSW SW01 Bit0 is set to “1”, the following service error codes are displayed when an error occurs.

2-1 User’s error messege

"CARTRIDGE JAMMED"

Printing position correction failed

Cause: Carriage movement prevented by one of the following.

Damaged shaft. Parts deformed. (Carriage or guide frame) Insufficient grease.

Solution: Replace the shaft.

Replace the deformed parts. Apply more grease.

Cause: Bi-directional print displacement correction failed because the carriage motor is

out of step, or some similar reason.

Solution: Replace the carriage motor.

Home position error

Cause1: Tried to stop the carriage unit that has been moving or to move the carriage unit at a pouse by

force. Solution1: Do not touch the carriage unit other than cartridge replacement position. Cause2: Foreign body in carriage section. Solution2: Open flatbed ass’y and remove the foreign body . Cause3: Loose carriage belt. Solution3: Replace carriage unit Cause4: Carriage motor does not work. Solution4 (1) Switch power OFF/ON. (2) Replace carriage motor. Cause5: The position of the carriage cannot be detected (due to smears on the carriage

encoder film or SPCNT board failure). Solution5: (1) Switch power off/on. (2) Wipe the carriage encoder film with a cloth soaked with alcohol. (3) Replace the carriage encoder film. (4) Replace the SPCNT board.

Note:

This error message means the same as service error codes ##338 and ##340. When this error occurs in this model, it is not treated as a service error, but as a user error, and the error message is displayed.

“COVER OPEN”

Cause: You opened the scanning unit (printer cover) during an operation. Solution: Close the scanning unit (printer cover). Cause: Damaged scanner open arm ass’y, damaged scanner sensor arm, or SPCNT board ass’y failure. Solution: Replace the scanner open arm ass’y, replace the scanner sensor arm, or replace the SPCNT board

ass’y.

“CHECK PRINTER (PRESS [OK])” (##334 - ##336, ##343, ##345, ##346, ##352, ##356 - ##362)

Cause: The carriage unit does not move due to a foreign body in the carriage section. Solution: Open flatbed ass’y and remove the foreign body. If there is a paper jam, clear the paper jam. Cause: The printer’s internal unit has malfunctioned. Solution: Reinstall the BJ cartridge. Turn the power off and on. Check the service error code and refer to an appropriate solution. Cause: The waste ink tank (absorber) is nearly full. Solution: Replace the waste ink tank (absorber).

Note:

When replacing the waste ink absorber, you need to reset the waste ink volume counter. [Refer to 3-3 Adjustment/Settings (6) Service mode.]

“MEMORY FULL”

Cause: The machine’s memory is full because you tried to copy a very detailed document. Solution: Divide the document and copy each part separately. Cause: The machine’s memory is full because it has received too many documents in the memory

receiving mode. (MP780 only) Solution: Print out any documents, which are stored in memory. Then start the operation again. If the

memory contains any documents yo u d o not need , del et e th em.

“MEMORY CLEARED (PRESS [OK])”

Cause: After receiving data in the memory receiving mode, the power is off due to a service interruption,

etc., and then the image data received in the memory receiving mode is cleared.

Solution: Press [OK] to go back to the standby status.

2-7-2 Procedures for processing communication problems

If the problem proves to be communication trouble, deal with it according to the following procedures. (1) Study the conditions at the time of trouble as closely as possible. Record or keep the items listed below.

a) Operations at the time of trouble. Document number, transmission mode, error occurrence timing call set-up method (auto dialing etc.) b) Sample of defective picture (When receiving) c) LCD display at the time of trouble. d) Communication management report at the time of trouble. e) User's name, telephone number (to contact), Fax number, model name. f) User's name, of the other party, telephone number (to contact), Fax number, model name, name of servicemen in charge. g) Frequency of trouble and error code (##100 etc.). h) Condition of the other party's facsimile: Transmitted/received page number? Automatic or manual? Error occurred? The receive condition? etc.

NOTE:

When visiting a user with a trouble report, a) can be known by outputting the error protocol data (or error dump), and g) can be known by outputting the total transaction report (or the system error data

list). (2) Test communication according to flowchart procedures appearing on the next page. * Carry out the tests with the actual lines on each item, verify the symptoms and record it. * In the case of trouble with another manufacturer's facsimile, refer to the flowchart for troubles with other manufacture's. (3) Finally, process over by judging systematically all the data.

NOTE:

If the other party's facsimile is that of another manufacturer and there is nothing wrong with your

customer's machine, it is recommended that you ask your customer to contact the facsimile user of

the other party, so that the other party's facsimile is checked by the dealer. "Call the service station"

in the flowchart means that problems may occur with regard to the communication compatibility of

facsimile, consult the matter with the staff in charge at the service station. To quicken the resolving of

the problem, report the information listed in (1) above.
