During this err time, I swap other normal parts for the same model ,
Main controller PCB ,
Carriage unit ,
Purge unit ,
printhead ,
carriage drive motor ,
carriage HP sensor ,
linear encoder ,
power PCB ,
2F26, still not fixed when I turn on ,

Any body can help me???

Thank u to sharing !!

I have done the cleaning action of the rail,

The machine is turned on,
carriage has moved to the left and then the right,
but did not touch the carriage the HP sensor
Then the carriage on the slide to the central ,
then LCD display 2F26 ..
...

machine parts can be replaced also replace ,
the only cable and cover did not change,
O!! my God!

If you "REALLY" have replaced what you say, than there is nothing else to replace.

As I said - clean many times with a glass cleaner the shaft. At least 7-8 times thoroughly.

A lot of people say "yes I did clean" and in fact they didn't clean enough.

If the friction on the iron shaft is slightly different - you will get 2F26

Of course there might be other problems but to clean first involves just a piece of cloth and a glass cleaner (no other spare parts needed )

Indeed,
My other colleagues do not believe that ,
almost replace all the parts are still unable to troubleshoot,
They also help repair,
Finally, they believe,
Really very strangely 2F26,
Because really can not be solved,
Why I am here to ask anybody for advice,

Indeed,
we have not any lube EY-1 ,
I also admit that I only just used alcohol wipe,
And then a little bit of silicone oil to wipe rail,
Then use a clean cloth to wipe
After wiping the frictional force is small,
If you wipe once is not enough,
To work tomorrow, I will be efforts to wipe a few times,
Here and would like to thank the recommendation of V-P sr.!

[V-P]

yes yes ,

I believe - you believe

Good luck !

after replacing the Carriage
All Carriage related error codes need to get reset in the logic board (Main Controller PCB).
remove the Print Head out and boot up printer in the Service mode, let the printer initialize and then without performing any adjustment(s) turn the power switch Off, then turn it back On again in the Operator mode and waited for the printer to ask for PrintHead.

This process may resolve the problem.

Did u remove protective mylar to the Linear Scale
scale is blurred with this mylar attached, causing Linear Encoder to falsely read it.

Bad Flex Cables. Micro cracks can cause numerous problems
Flexible Flat Cable Checker (FCC Checker) would be a good idea to find out about the condition of the Flex Cable.

Thank you, Mr. Teckat and any recommended predecessors here first,
Because your recommendations will guide the direction of maintenance,
I will go and try Teckat said,

Because it was engaged in for maintenance plotter 10 years since,
First know that this step can initialize the machine,
any trainer or service namual never said about that!!!
This is very valuable information for me !!

I had swap linear scale for iPF760 ,
still unsolved ,
both of 750/760 models ,
almost 95% parts the same ,
and parts can swap to test ,
so not problem for Teckat said !!

This Flexible Flat Cable Checker maintenance tools
Four years ago,I used,
On iPF8000/8100/8300 models detect very convenient,
But for the new machine, or iPF700 series,
I would prefer to replace a whole new set of customers,
Because a disassembly too difficult!!!

Never swap Print Heads from printer to printer
