3B	Printing area error.
3C	Sudden carriage stop during printing.
41	The head drive voltage has not been turned from Low toHigh within the specified time.	• Carriage ASSY • Main PCB • Print head unit • Power supply PCB

42	The head drive voltage has not been turned from High toLow within the specified time.
43	Head thermistor broken.	• Print head unit • Carriage ASSY • Main PCB
44	Head thermistor short-circuited.
45	Flushing operation abnormally ended. (The headtemperature has arisen abnormally.)	• Print head unit
46	The number of performed purge sequences has reachedthe limit.	• Ink absorber box • Main PCB
47	Head parameter stored in the EEPROM on either of thetwo print heads is invalid. (This code may appear only in the maintenance mode.)	• Print head unit • Main PCB • Power supply PCB
4B	Abnormal carriage travel speed detected when the powerwas applied.	• Encoder strip (Anystains or scratches? Hooked correctly?) • Purge unit • Main chassis • Carriage ASSY • Main PCB
4D	Error of the reference voltage in the video capture circuit.	• Main PCB
4E	Out of the allowable range of the head drive voltagedesigned for individual print head properties.	• Main PCB • Print head unit
50	The purge cam HP switch does not come ON even afterthe purge cam has been driven by the specified number ofpulses.	• Purge unit • Purge-related gears onthe main chassis (Purgegears 18 and 19, gearstopper, and purgebevel gear 18) • Main chassis • Paper feed motor • Main PCB
51	The purge cam HP switch does not go OFF even after thepurge cam has been driven by the specified number ofpulses.
52	The pump switching cam HP switch does not come ONeven after the switching cam has been driven by thespecified number of pulses.
53	The pump switching cam HP switch does not go OFF evenafter the switching cam has been driven by the specifiednumber of pulses.
73	Any of the four ink cartridges is not set into place.	• Ink cartridges • Carriage PCB • Head flat cables • Main PCB
82	Recording paper feeding error.	• ASF • Registration sensor actuator • Main PCB

83	Recording paper jam. (The registration sensor sticks to OFF, indicating thatpaper has jammed.)	• Registration sensor actuator • Main PCB
84	Recording paper jam. (The paper ejection sensor has detected a paper jam.)	• Paper ejection sensor actuator • Registration sensor actuator • Main PCB
88	Recording paper jam. (Even after the registration sensor has come ON, thepaper ejection sensor does not detect paper.)
A1	Scanner unit opened.	• Scanner open sensorPCB and open sensor actuator • Main PCB • Document tray ASSYand scanner unit
A2	Document too long to scan.	• Document front sensor actuator • Document rear sensor actuator • Control panel PCB • Document sensor PCB • Document feed roller • ADF motor • Main PCB
A3	Document not detected by the document rear sensor.
A4	50% or more faulty of white level data.	• CCD unit • Main PCB
A7	One-line feeding timeout.
A8	One-line scanning timeout.
AC	Less than 50% faulty of white level data.	• CCD unit • Main PCB
AE	The CCD HP sensor sticks to OFF, indicating that theCCD unit has not returned to the home position.	• CCD unit • Main PCB • CCD motor • CCD drive belt
AF	The CCD HP sensor sticks to ON, indicating that the CCDunit has stayed in the home position.
B1	Dark level offset data error.
B2	Gain control data error.
B3	Scan area left edge detection error.

B4	Scan area right edge detection error.
B5	Scan magnification (checked with the black marks printedon the white-level reference film) less than the specifiedvalue.
B6	Scan magnification (checked with the black marks printedon the white-level reference film) greater than the specifiedvalue.
BE	Detection error of the black marks printed on the white-level reference film.
BF	Detection error of ADF scanning position.

E6	Write error in EEPROM.	• Main PCB
E8	Data scanning error during transmission.	• CCD unit • Main PCB
EA	Document removed at phase B.
F6	PC interface error.	• Interface cable • Main PCB
