T2500 "printhead replacement not complete"

Re: T2500 "printhead replacement not complete"

I assume (ASS-U-ME) it is a breakdown of the black rubber seals at each needle in the service station SS, not sealing against the cartridge but am not certain, but then there is the seal between the needles and the cartridges. I don't really know exactly where the air is coming in. It might be leaking at the carriage end and the air flowing from there back towards the SS. Might be leaking at both ends, carriage and SS. The cartridges were all pretty new with the exception of the replacement magenta which expired in 2021. ....I remember DJ 5000s & 5500s leaking at the carriage. I could watch the air being sucked in and traveling all the way back towards the ISS. This T2500 has about 360,000 +/- cycles on it.

In fact, you have air on both sides, but considering that the head is empty or almost empty it may be that the air is coming from the head. however it is the replacement of the tubes is the best thing.
Yes the problem with DJ5000 can be solved.

Re: T2500 "printhead replacement not complete"

My goodness, what a trailing cable routing nightmare IMO. How do I best insert the trailing cable at the main pca? Up underneath with low clearance. I will try to squeeze my fingers in that tight spot. Maybe I can slide the E-box forward a bit. Not tackled it yet. Ink tubes assembly is almost here.

Re: T2500 "printhead replacement not complete"

I have never replaced the tubes on those models and am not aware of the situation.
But take the time to do it calmly and you will complete the replacement.

Re: T2500 "printhead replacement not complete"

I can get to the trailing cable connection at the main pca by removing 2 back panels.

Re: T2500 "printhead replacement not complete"

BTW, the cyan and magenta ink tubes were leaking in the right or front panel side ink supply station ISS. Not profusely but noticeably. There had been no leaking to the exterior (not observable from the outside) but the ISS leakage catchment at the bottom of the ISS can hold a bit of ink.

Re: T2500 "printhead replacement not complete"

Finally! Printhead replacement complete! after replacing ink tubes assembly. Again was letting air in and leaking ink at the right (front panel side) ink supply station--leaky ink tubes; there was a bit of air in one of the shades of black ink tubes, not sure which one. Tubes air leakage and ink leakage appears to have been the problem. The primer assembly seemed to be somewhat deficient in that the old one for the upper primer (cyan, magenta, PK, and Gray) did not seem to relieve pressure during the test and with me blocking the tube. The new replacement primer assembly did seem to relieve pressure at the upper primer when tube was blocked.

I hope it keeps working!

Thanks for all input!

BTW, I did find that LPS Computer would rebuild these ink tubes for $99 plus shipping. But I had already ordered a NOS ink tubes assembly when I found that out.

Diagnostic print attached.

Re: T2500 "printhead replacement not complete"

Massimo, Kiran, and Copyman, thanks a lot for your input! I did not strongly suspect the ink tubes assembly since I saw no leaks to the outside, and at first, did not see a lot of air in the tubes except when I pulled the right end cover off and saw a lot! of air in the magenta and yellow ink tubes and ultimately saw cyan and magenta ink dripping down into the right ISS. And did not get a 24:10 leak error until the 3rd or 4th ink leakage test. Thanks again for your input!

Re: T2500 "printhead replacement not complete"

Hi pbrooks259,

I have been following all your chats concerning this problem. Seem to have a similar challenge. Could you possibly share with me the process you under went to replace the Ink tube System. I have already ordered the ink tubes for the same machine. I also notice a lot of Air in the tubes and links around the SS. I have replace ink tubes before but that was on the 5000 and 5500 which came with startup printheads. The T2500 is a lot different. My error is the same as yours.

Re: T2500 "printhead replacement not complete"

Hi, obtain the service manual here. Therein you will find the steps for removal and replacement of the ink tubes assembly (tubes and trailing cable):

Re: T2500 "printhead replacement not complete"

Hi there is one more problem I need the Pin for the Diagnostics menu. Are you able to share it please?

[pbrooks259]

Re: T2500 "printhead replacement not complete"

Hi, I think the code to enter the diagnostic menu is: 1714 and it should be in the service manual.

Re: T2500 "printhead replacement not complete"

Hi everyone.
Here is what I have done before I could install a new Ink tube system, wanted to try and run the Purge Tubes utilities and it run okay. I have replaced All the ink Cartridges successfully. Reached the Stage of inserting a new PrintHead and got the following message.

Replace Printhead
The Printhead failed to complete the replacement process.
Replace Printhead
Press OK to continue with printhead replacement.

Colour failure:------ /PkG - C M -
Printhead Status: 0x80010

Before I Pleas note this is a New Printhead I've installed. The only thing I noticed before installation was the on the Printhead was
INSTALL BY:
27-Jan-2020. Could this be the Problem?

I have tried the 1st Printhead that failed which I suspect failed because there was air pockets in the Tubes. It has come up with the same message.

Colour failure:------ /PkG - C M -
Printhead Status: 0x80010

but what I have noticed now is that there are no visible Air pockets as beforeI ran the Purge tubes. I trust is an indication that the Primer is working okay.

Please HELP me understand. Otherwise I need to get back to the suppliers for a replacement.

Re: T2500 "Colour Failure": ----- /PkG - C- M -" "Printhead Status: 0x80010"

This is the Messge I got after running Purge tubes. The cartridges installed correctly by but it came to the Printhead I got the messege.

"Colour Failure": ----- /PkG - C- M -"
"Printhead Status: 0x80010"

What I have noticed is that there is no ink being filled in the last Head.

Any Help will be appreciated.
