Question about Printers & Copiers
This error relates to the encoder strip for the carriage motor. The encoder strip is like a piece of graph paper and the head has an eye that reads how many lines it passes. This is so the machine know exactly where the head is at any point.
The error means that the machine is not correctly reading the encoder impulses. This could be because the encoder has broken, the eye has gone blind or a circuit board or cable has become faulty. It could be that if you have done maintenance that one of the connectors has been replaced with incorrect polarity.

In most cases the printer driver software can have errors while being in use or is shut down. So to reset remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and then connect the Printer to be detected as a new hardware as it will be installed. Now check the printer properties to see the ink levels.
Activate head cleaning before a test is taken . Sometimes it is possible that the head is not reacting to the need of the PC command or can be an issue with ink drying or poor ink cartridge contacts. Sometimes the power supply unit must be checked as a poor SMPS unit can deliver low voltage and cause issues to the printer function. Check all the leads and connections of the mother board , the tags to the ink cartridge. Also check the mechanical settings of the ink cartridge , if jammed or tight remove motor and manually free the drive before it is set back.
