2-2. Service Call Errors (by Cyclic Blinking in Orange (Alarm LED) and Green (COPY button), or Alarm LED Lit in Orange) Service call errors are indicated by the number of cycles the Alarm LED and COPY button blink, and the corresponding error code is displayed on the LCD. Cycles of blinking in orange (Alarm LED) and green (COPY button) Error Error code Conditions Solution (Replacement of listed parts, which are likely to be faulty) 2 times Carriage error [5100] An error occurred in the carriage encoder signal. - Carriage unit - Timing slit film - Logic board - Carriage motor 3 times Line feed error [6000] An error occurred in the LF encoder signal. - Timing sensor unit - Timing slit disk film - Feed roller - Platen unit - Logic board - Paper feed motor 4 times Purge cam sensor error [5C00] An error occurred in the purge unit. - Purge unit - Logic board 5 times ASF (cam) sensor error [5700] This error takes place when feeding paper from the ASF after an error occurred in the ASF cam sensor. - Sheet feed unit 6 times Internal temperature error [5400] The internal temperature is not proper. - Logic board - Carriage unit 7 times Waste ink [5B00] The waste ink absorber is full. absorber full - Ink absorber kit 8 times Print head [5200] The print head temperature exceeded the specified temperature rise value. error - Print head - Logic board 9 times EEPROM error [6800] A problem occurred in writing to the EEPROM. - Logic board 11 times Carriage lift mechanism error [5110] The carriage did not move up or down properly. - PR lift shaft - Sheet feed unit - Logic board - Carriage lift sensor unit 12 times AP position error [6A00] An error occurred in the AP motor during purging operation. - Sheet feed unit - Logic board - Purge unit 13 times Paper feed [6B00] An error occurred in the paper feed motor. position error - Sheet feed unit - Logic board 14 times Paper feed cam [6B10] An error occurred in the paper feed cam sensor during - Sheet feed unit sensor error paper feeding from the front paper feed cassette. - Logic board This error is also indicated when the waste ink counter is 60% or more, and a paper jam occurs in the under guide. 15 times USB Host VBUS overcurrent [9000] The USB Host VBUS is overloaded. - Logic board 16 times Valve sensor [6C00] An error occurred in the valve sensor during cleaning. - Logic board error - Purge unit 17 times Motor driver [6D00] The AD conversion value indicating the motor driver - Logic board error temperature is not proper. 19 times Ink tank [6502] None of the ink tank position is detected. position sensor error - Platen unit - Logic board 20 times Other hardware [6500] The PCI bus error is detected by the ASIC. error - Logic board 22 times Scanner error [5010] The scanner unit cannot detect the home position, or the scanner unit warming-up is not done properly at power-on.
