There are several issues that pertain to this code, including a service update. If your printer is still under warranty – visit your local ASC, find one
here, this issue is covered! First off, the Service Update, the encoder strip needs to be cleaned with a lint free cloth. The encoder strip is responsible for relaying the position of the print head to the main pcb. If the encoder strip gets dirty, many different problems can occur. The encoder strip is exposed, which allows grease, paper dust, finger prints, ink, etc. to get onto the encoder strip. (The white strip when you open the scanner cover)
If the machine still errors, the encoder strip needs to be replaced – Part Number LS4467001
If the machine still errors, replace the carriage PCB assembly – Part Number LS6543001
If the machine still errors, replace the Printhead – Part Number LK3211001
If the machine still errors, replace the Main PCB assembly – Part Number LT0284011
