Question about Lexmark X4270 All-In-One InkJet Printer
I think you should be able to access the strip that is probably causing the problem.
Most all of these machines use a Mylar tape with extremely fine vertical lines to keep track of where they are going; the thin lines are interpreted by photo-optics and the printer counts lines to control its position.
The strip runs completely across the width of the printer and the sensor is located in the carriage.
With the printer turned off, open the section you use to replace the cartridges and with a flashlight peer inside to locate the strip.
It is probably contaminated with dust or some wayward ink.
Use a paper towel that doesn't produce fuzz or 'micro-fabric' and spray a little wndow cleaner onto the cloth - NOT in the printer.
Gently pinch the strip between your cloth-covered fingers and travel back and forth a couple of times.
Check the towel/cloth to see if in fact some grubby stuff is on it.
If so, you are probably back in business.
If not, you may have some fuzz trapped in the track the strip runs in.
To access this slot, you will have to BS the printer by opening the machine with the power on this time, VERY carefully draw a clean paper towel (non-fuzzy again, don't want more lint inside) along the Mylar strip and through the slot in the carriage in which it rides.
With both of these accomplished, your machine shouldn't get lost on its trips back and forth.
