WF-4740 start up, but stops and doesn't complete in Inkjet Printers Issues Posted January 10, 2021 · Report reply Since I posted this I have called Epson who directed me to my nearest service center, 136 miles from here. They told me I could send it to them and there would be a $90 diagnostic charge which could be applied to a repair. I will probably write off the $20 I spent here for a Service manual and send this printer to Epson's recycling program. I will also bid good riddance to Epson. I don't have a big issue with this 3 year old printer requiring service or repair, but making it so hard to get service leaves me with a really bad taste. I remain open to suggestions and assistance reading the user log.dat file I was able to snag on a thumb drive. It appears to be a binary file.
