Service error 6502 generally means that your cartridge chips cannot be recognized. The primary causes of this error
message are:
1- Covering of the LED light at the back of the chip
2- Incorrect chip positioning on the cartridge. Again ensure that no tape, glue etc is covering of impeding LED on
the rear of the chips.
3- The lid of the printer is open whilst testing-This will cause the ambient light to interfere with the LED lights which
are checked as the print head moves from left to right.
4- The LED on one or more of the cartridges has been damaged when removing it from the original cartridge
5- The chips have been mixed up and fitted to the incorrect CISS cartridge.(i.e. Yellow OEM cartridge chip on a
Blue CISS cartridge).These chips are color specific and need to be fitted to the corresponding colored CISS
cartridge
6- Ink is covering the cartridge chip of a sensitive area of the cartridge and preventing the LED light sensor from
functioning
