Any old Neo 1 family still here?
I was getting a 00010037 - Head thermistor error - Replace printhead (but i'm thinking something else is causing the error because there is no reason it should have thrown this error)
so I replaced the printhead still have the error code. Not 1 drop of ink has gone through the head as the machine won't even go through a startup cycle. So I replaced the Motherboard thinking I might have a problem there somewhere sending a false code still showing the error.
Any other ideas? I'm at a loss???

Replace the ribbon cables that goes to the head #0 & 00

 

[twistinthewick]

I did that before I changed the motherboard.

Have you checked the ribbon all the way back to the motherboard? Are the cables the correct way around at the interface behind the printer's front panel?

Hello John,
I found a barb that was alittle out of place where the #5 cable plugged in. Repaired it and the 00037 error is gone. NOW I have a 00010000 error that should be the encoder strip clean the veritcal strip and the disk shut the machine down a few times it won't clear. I also tried moving machine to the center of the bed and starting it will move to the back and front but will not start up.
Any other tricks up your sleeve John Cooper???

I just found this remedy I'm going to check.

Description
PF Motor Encoder check error
During initial operation at power on or during PF Motor operation, there may be a case where the encoder pulse signal can not be recognized at specified intervals. In such a case, this message is displayed and the printer stops operating.

Causes
• Disconnected connector for the PF Encoder Sensor. • Disconnected connector for the PF Motor. • Broken wire for the PF Motor Encoder. • Inverted wiring for A and B pulses. • Inverted wiring for the PF Motor. • PF Motor short • PF Motor continuous excitation (voltage applied continuously, motor revolutions unusual) • Broken power supply fuse for the PF motor driver (on the Main Board )

Hi Cathie

I'm not in the shop just now so something for you to check - on top of the printhead there's a very short ribbon cable (maybe 5 or 6 threads in it). The ribbon cable is folded very sharply and can often break.

Try take a look at that, remove it to be sure it's in good condition and, if you have a meter check each line for continuity.

Hope you understood that

John

Hi,

Sorry for problems with 4880, it's amazing how many DTG'ers keep them
running for so long. Flex cables are often the issue, sharp bends right
at where pins are cause most breakages - the pin/wire joint fails
and it is very hard to see.

Also note that the connectors them selves can have issues, check inside
for any left over pin material since that can also cause a short. Make sure
all pins look "good" and will make contact. A loose connector is not your
friend!

As you all know, the connections between the interface board and printer
are many, I have found on many occasions the jumper cables have bad
pins that are either have tips missing, bent up so no connect or bent
sideways to short another pin - check carefully. I know probably
redundant but can't emphasise enough. Removing a cable that looks
good can go IN badly too.

Keep me posted on what is going on, always here to try and help.

@NeoFlexExpert

Just wondering if you used to work at AA or were you a contributor here on TSF under a different name

 

[NeoFlexExpert]

Hi,

I am engineer at AA, designed Neo1 boards for transport/printer, Neo2 system and Neo3. I am authorized by Peter to offer technical support and
upgrades to P800.

As you know on 4880 it was solidly built with no expense spared on
engineering. So, a multitude of cables/connectors from head to mother
board. I have found best way is to buzz out the actual connections to
verify it's not a connector/cable/board issue. I am working on a test
matrix so you can quickly test whats going on before replacing a load
of boards/cables that might not need to be.

Hope by this week to get that done.

Finally had some time to devote to my machine put the old motherboard in and now my only error is 00010035.So I'm cleaning everything from it sitting for so long. I will check in later and let you know how I made out.

 

[NeoFlexExpert]

O.K,

Pump phase sensor check or try fuse on main board that runs pump.
Does pump turn/spin?

Lmk if I can help.

Angie and I spent a week at AA learning all about the Neo 1 so I'm guessing we might have met

Cheers

Possibly, I'm the good looking one, James Bond esq with a British accent.
I'm always shaken but not stirred LOL. Keep me posted of your
adventures with your Neo1, always here to help and of course beers
are always on Peter

NeoFlexExpert is long time working partner(until now) and good friend to me. Very trusty guy and devoted person with deep knowledge. He will do all to match your needs. Sometime it will cost you, lol.
I am glad to see NeoFlex forum is starting to get some fun as before.
John, He is from UK also. And his English is original not like mine. LMAO
Cheers! Beers are on me always.

@NeoFlexExpert, it's good to see you helping here. and @allamerican-aeoon (NeoFather), it's great to see you around here again!

my Neo1 is still going after 6 years.

I'm ready to put my Neo to sleep. I have never had an issue I wasn't able to fix! This time everytime I change a part I get a new error. I was getting the 100035 pump error replaced the pump and capping station still had the error. So I replaced the motherboard again I don't know if I still have the error because I can't clear a #$%DAMN! No Maint. Tank error, I have 2 4880's for parts so I had 3 maint. tanks to switch out didn't clear it. Then I took out the sensor 3 times didn't work, I changed the chip on one of the tanks didn't work!
I checked all my connections everything looks good. It breaks my heart because I really enjoyed DTG. I thought I knew my machine pretty well but I have never encountered error after error like I am now.
Anyone know what might be giving me that error.
I'm contemplating putting her out of her misery and purchasing a Katana.
She has given me a good run.

That is sad news Cathie Don't like to see the demise of a Neo as there has to be a reason behind the problems you're seeing.

I've experienced problems similar to those you're experiencing and often discovered the error reported sends you on a wild goose chase! I also know what it's like when you reach that point of surrender and at that point, I'd really like a Neo expert to take over - a fresh pair of eyes! But, you are a Neo expert, you like me, know the machine inside out.

When I reach this point I usually flush the ink out and fill with cleaning solution or similar and walk away for a week or so. When I return I check all the cables making sure there's no burns or corrosion and ensuring they're the right way around - it's so easy to put a cable in backwards and then of course there's the 'folded back track'!!

You did check that small flat cable at the top of the printhead didn't you? Sometimes it looks good but under a magnifying glass ......

So far I've been lucky and I really hope you get lucky too.

John

John,
I have looked at and tried everything I can think of. I numbered all the cables before I uninstalled and reinstalled the motherboard to make sure nothing was installed wrong, I changed the 00 and 000 cables, small cable on top of print carriage,pump and cap station, waste tank(with 3 different ones), waste tank chip, waste tank sensor on machine frame(with 3 different sensors)!
That is about the extent of my reasoning of what could be throwing my errors.

 

[23spiderman]

i get this error every time i remove my maintenance tank. once i get the error, i just remove the tank and put back in, and it goes away. once thing that will trigger this is if the tank isn't level. like John, i print with my end cap removed. the maintenance tank doesn't have any support and will droop. i use 2 wooden nickels and wedge them between the tank and the metal frame, and it fixes this issue.

i know you know all of this, but this is what i do when i get that error.

I use a similar support.
