T2500 "printhead replacement not complete"

Re: T2500 "printhead replacement not complete"

You can not purge a tube assembly that has already been in use. That function is only for a new tube assembly and requires 'setup' printheads to work. They allow the air to escape until the ink reaches them.

You likely have both a bad printhead and a bad tube assembly. The date on the supplies is purely for the warranty; I've had 10 year old printheads work just fine.

Once air gets in the printhead it's basically ruined. There's no way (that I know of) to refill the printhead once this happens. You need to either suck the air out of the tubes with a syringe, or better yet, replace the tube assembly. If it's letting air in, regardless of how much you suck the air out, it's going to get in again and then destroy a printhead(s).

LPS Computer sells refurbished tube assemblies. Ink Tube System for DesignJet T920 T1500 T2500 T3500, CR357-67027

Put a new tube assembly in and new printhead(s) and you'll be golden.

Oh no didn't know about the setup heads, they didn't come with the ink Tube System. Does LPS Computer stock Setup Heads. I already have new Ink tube System. Please advise.

Re: T2500 "printhead replacement not complete"

Where did you get the tube assembly from? If it came from HP, it would include the setup heads.

LPS sends a syringe with their tube assemblies for drawing the air out and the ink in to the tubes with most of their tube assemblies. Some like the 4000/Z6xx-series come with setup printheads.

Re: T2500 "printhead replacement not complete"

I got the tubes from Aliexpress and they are intact I have not used them yet. To be honest I haven’t come across setup heads for the T2530. These are new machines I haven’t seen them in service manual either, I’ve work on the DJ 500,510 5000 and Z6200 yes and used the setups on them. This is new. If someone can help me on how to fill the new tubes with ink I would be very glade or else where I can get the setup heads for T2530 that would even be better. I plan to get syringe from LPS also.

any help will be much appreciated

Re: T2500 "printhead replacement not complete"

Follow this in the service manual on pg. 373--this is stated after the steps for ink tubes assembly removal. My ink tubes assembly came with a new printhead. Follow the steps below. The ink tubes assy. did not include setup printheads nor did I need them.:

Installation
1. Install the new ink tubes and trailing cable. Reassemble all the parts, without inserting the ink cartridges or
the printhead.
2. Power on the printer and enter the Service Utilities Menu, see Entering the Service Utilities Menu
on page 216. In this menu, reset the Tubes and Trailing Cable usage counter, see Reset Life Counters
on page 221. Then, run the Purge Tubes utility, and follow the steps prompted by the printer, see Purge
Tubes on page 217.

Thank you for taking your time to respond to my woes. I'll give feedback when I get a new Printhead and try the procedure as advised. It may take 2-4 weeks before head comes.

Re: T2500 "printhead replacement not complete"

I received a New Printhead and proceeded with the replacement of the Ink tube System and reset the counters for Tubes and trailer.

I followed all the steps as advised and the system still came up with the same error as before "Replace Printhead".

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

Color failure: - - - - - /PkG - CM -
Printhead Status: 0x80010

When I check the new link tubes I noticed pockets of Air almost all the tubes. I've run out of ideas. Maybe I should have also replaced the Primer motor. the Service station should be okay otherwise the system would have given an error in fact it dry as it is. Can't figure out where the Air is entering from because this is a new ink tube system.

Please help Any Ideas

Re: T2500 "printhead replacement not complete"

Did you purge the air from the tubes first using setup printheads? Or a syringe??

Re: T2500 "printhead replacement not complete"

Sorry the tubes assembly replacement did not seem to work. I did the opposite--I replaced the primers to no avail. But replaced later the ink tubes assy. and had success with that replacement.

I THINK I did see better priming of the printhead after replacing the primers, but printhead replacement still failed, so I had to replace the ink tubes assy.

I think I would replace the primers, but I am not totally sure of the exact soln. MAYBE one of the primers is just not up to priming the 2 or 4 lines that it primes, and PERHAPS that is why you see air in the lines. I THINK you get both primers in the box. And as I recall primers are ABOUT $50 or so, or they were.

Also, for all the ink tubes that had air in them, I got new ink cartridges as I had heard that air could also get into the ink cartridges and could subsequently be released into the ink tubes and get to the printhead. I suppose that is possible. I replaced those ink cartridges simply to guard against such possible air infiltration.
