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 2 times Carriage error [5100] An error occurred in the carriage encoder signal. 3 times Line feed error [6000] An error occurred in the LF encoder signal. Solution (Replacement of listed parts, which are likely to be faulty) - Carriage unit - Timing slit film - Logic board ass'y - Carriage motor - Timing sensor unit - Timing slit disk film - Feed roller ass'y - Platen unit - Logic board ass'y - Paper feed motor 4 times 5 times 6 times 7 times 8 times 9 times 11 times 12 times 13 times 14 times 15 times 16 times 17 times 19 times 20 times Purge cam [5C00] An error occurred in the purge unit. sensor error - Purge unit - Logic board ass'y ASF (cam) sensor error [5700] This error takes place when feeding paper from - Sheet feed unit the ASF after an error occurred in the ASF cam sensor. Internal temperature error Waste ink absorber full Print head temperature rise error [5400] The internal temperature is not proper. [5B00] The waste ink absorber is full. [5200] The print head temperature exceeded the specified value. - Logic board ass'y - Ink absorber kit - Print head - Logic board ass'y EEPROM error [6800] A problem occurred in writing to the EEPROM. Carriage lift mechanism error [5110] The carriage did not move up or down properly. - Logic board ass'y - PR lift shaft ass'y - Sheet feed unit - Logic board ass'y - Carriage lift sensor unit AP position [6A00] An error occurred in the AP motor during error purging operation. - Sheet feed unit - Logic board ass'y - Purge unit Paper feed [6B00] An error occurred in the paper feed motor. position error - Sheet feed unit - Logic board ass'y Paper feed cam [6B10] An error occurred in the paper feed cam sensor - Sheet feed unit sensor error during paper feeding from the front paper feed - Logic board ass'y cassette. This error is also indicated when the waste ink counter is 60% or more, and a paper jam occurs in the under guide. USB Host VBUS overcurrent [9000] The USB Host VBUS is overloaded. - Logic board ass'y Valve sensor [6C00] An error occurred in the valve sensor during error cleaning. Motor driver [6D00] The AD conversion value indicating the motor error driver temperature is not proper. Ink tank [6502] None of the ink tank position is detected. position sensor error - Logic board ass'y - Purge unit - Logic board ass'y - Platen unit - Logic board ass'y Other hardware [6500] The PCI bus error is detected by the ASIC. error - Logic board ass'y 1-7
