Xc540 error

It's not really, maybe just bad wording on my end. When I move it by hand etc it's smooth, no snags or anything with or without the scan motor installed. Only does the "jerk" thing when it tried to move over the caps/cleaning area like it normally would at startup. Can hear it trying to move and see very slight fractional turn then stops and does it again.
It could be staying in the locked position, it moves the cut carriage then head carriage goes to locked position then does the issue described above.
Certainly will.

If it's going to be some time before you get the motor, you should soak the print heads so they don't dry out and give you more problems...

Tracking is telling me it will be here Friday along with the spring. Still might go ahead and do that though since they are all new printheads and cost way too much money to risk drying them out, thanks for the tip.
Spring installed, fixed my cutter issue. Installed the new scan motor and still getting the error code. Ran linear encoder and calibration plus aging and redid limit before trying to turn it on in standard mode. Doing the exact same thing as before, not sure what else to look for.

Jim Hancock's back? Sweet! Are you taking referrals?

Yes indeed! Good to be back! I'm only doing phone support now, semi-retired... Also limited board repair, primarily output transistor checking and replacement. Send 'em my way!

OK, now it's getting strange. I felt like the encoder sensor was ok, based on running the linear encoder step and you getting consistent numbers on the display. I would turn out the lights and look down behind the print head carriage and see if there is red light coming out of the sensor. I don't think you changed the encoder sensor, but it might be worth a shot. Also, before you change it, reseat all 6 of the big ribbon cables that attach to the carriage board. Before you reseat them, examine the traces at the end of the cables to make sure they are clean and undamaged. Insure they are in straight and square when installed in the connectors. I don't think it' the carriage board itself, as the signals for the encoder sensor travel from the encoder sensor connector on the board to the ribbon connector on a trace, no circuitry involved.
BTW, the Initialize the Limit step should be the very first step, as this establishes a zero point for all the calibrations. So, Initialize the Limit, Linear Encoder, Linear Calibration, Aging.

Red light is on, carriage board and every ribbon cable in this machine is new. I checked they are all seated properly with no damage and just reran the Linear items in that sequence (did it wrong last time) but still the same issue.

I know you said in an earlier post you cleaned the encoder strip, and I suggested removing the encoder strip from the printer and cleaning it with acetone. Did you do this? When you do, be very careful not to lose the tension spring. Before you clean it, examine the strip closely, especially around the end close to the home position. Hopefully you see something wrong, like ink or a scratch... IPA is ok for cleaning the strip, but it doesn't always get everything. Plus, depending on the grade, it may contain some percentage of water, as much as 30%. The encoder strip is a piece of graphics film, processed in water-based chemistry, and can be damaged by lower grades of alcohol. The strip is impervious to acetone and acetone will remove a lot more ink than alcohol, like all of it. Wet the microfiber cloth with acetone, fold it onto both side of the strip, putting pressure on it with your fingers and pull it through. Do this several times until the cloth remains clean and the strip squeaks when you pull it through. Wear gloves, both for safety and to keep from putting finger oil on the encoder strip. Then replace it and rerun the 3 steps and hope for the best! I've cleaned the strip on every printer I've ever worked on, which is a few hundred various printers, this way and never damaged one.
I did, but no acetone here so just used 99% IPA again. I did not see any scratches or ink etc though. Might just replace it since they are cheap, probably should have tried that first compared to spending hundreds on a motor but now I have an extra that seems to be perfectly functional.

I would also try a new encoder sensor. Don't be to bummed about the scan motor, because if you use the printer a lot and keep it a long time, the scan motor will eventually go, as it is the most used motor in the machine, and you have a spare on hand. We'll stick with you to try to figure this one out.

I agree with Jim. I have had ones before where the strip looked fine, but it was just not reading it properly for the first inch on the far right, and this is the bit the head uses to initialise itself and check where it is. Putting on a new strip fixed it fine.
The senor too as with the head strike it may have damaged it somehow so it isn't getting a consistent reading

That is normal for most aftermarket ones as they are normally supplied longer than needed. You just cut it to the proper length and make a hole in the other end yourself for the fixing screw. The end with the hole is where the spring goes on the left hand side of the printer. The markings should go all the way to the end on the right hand side.
