Epson CX7400 E01 Error

Printer: Epson CX7400 Status: Error E-01 (paper jam error) It is an error on the printers mechanism side. The printer has been giving a E-01 error since the last one month. I tried everything. The printer service manual points out these possible errors: 1) Problem with scanner/ CR / PF motors (But they are fine) 2) The lever compression spring might have come off (It hasn't) 3) Issue with either the paper guide unit or CR scale (No problem here) 4) FFC encoder cable (No problem here either) So in short, I've given up fixing the print mechanism. Right now, I'm trying to salvage the scanner I've uploaded some pics 1) The mainboard - i59.tinypic.com/2mxh7ig.jpg 2) Mainboard zoom left - i62.tinypic.com/2rz487k.jpg 3) Mainboard zoom top - i62.tinypic.com/ac7trr.jpg 4) mainboard zoom right - i62.tinypic.com/20rs2e9.jpg So we have the following cables 1) Scanner FFC cable 2) Scanner motor cable 3) PE sensor cable 4) Main power supply cable 5) PF motor cable 6) CR motor cable 7) PF encoder FFC 8) Front display panel FFC 9) Head FFC 1 10) Head FFC 2 11) Head FFC 3 I've tried this: Removed all cables except 1, 2, 4 and 8 But I still get an E01 error which means the printer is stuck. It won't let me use the scanner Any solutions will be greatly helpful Thank you folks ---------------- Update: dated 13th January 2014 I took out the printer today. It was catching dust laying somewhere in the corner. I switched it on and to my surprise... IT STARTED WORKING AGAIN!!! It appears(an opinion from experience) that this error(E01) is not a hardware issue but rather a software issue. At some point in time the printer acquired this error which it then kept stored in its memory. The error may have generated and persisted for just a fraction of a second but the printers fail safe codes prevent it from disposing the error.The result is that no matter how many times I restart or dissemble it, it won't get fixed. The printers memory refuses to clear itself(the error). I had left my printer in the corner unplugged for more than a year. I'm not sure at what time period the memory ran out of internal juice(power). This is probably what reset the memory back to factory. With bricked routers, the solution to unbrick it is by shorting two legs of an IC. This printer must have a similar solution though this would require severe experimentation with the risk of frying the board. My sincere advise to those of you who face a similar problem is to let the printer sit in a corner unplugged for a month or two.
