Excellent. Thanks for letting us know.

Re: HPDJ Z3200ps photo printer with Error code 79:04 44" model
Kiran,
I got the thing fixed. I'll bet they thought they had the tensioner Murphy proofed, but I showed them wrong.
Precision roller does carry just the tensioner for around $20 or so I forget. I'm just happy to have that off my plate.
When I put the carriage back in and was setting the tension, I noticed that I had re-assembled the tensioner incorrectly.
Then I broke the upper bushing on the carriage, but I had one of those on hand.
After I put it back together everything worked. And I did see it pull out the shutter and close it.
I'm guessing it put just enough of a bind to throw it off. It was that or re-connecting the trailing cable. But I had re-seated
that cable earlier.
At any rate it is fixed and the customer is happy to have their machine back to 100%.
And I'm glad too.
Thanks very much for your suggestion to pull the carriage back out. I was getting tunnel vision on this one.

Don't you hate that? I've had two break on me.. one when I wasn't doing anything involving the belt or carriage. The only way to get the tensioner is to order the belt from HP. CH538-67018 Fortunately it's one of the belts that includes the tensioner. Some don't.

Well, I got the carriage out and looked at the bottom and it seemed clean to me. The sensor also seemed clean behind the shutter.
nothing unusual. Then the center piece for the tensioner pully broke. I'm off to get a part.

I don't know about the calibration (I assume it would be opened) but it must open when you do a color calibration or run the test on the color sensor.

I ran the calibration for the sensor and it passed and the shutter never opened either. When is it suppose to open?
I got the carriage out enough to access the shutter and it pulls out fairly easy. I did not feel any sticky-ness.

No.... the shutter only opens when the printer is doing a color calibration, or you run the test on the sensor.

Thanks for the tips. I'm here now and the customer just printed a nice poster and the shutter never opened. I assume the spring on the right side is to close
the shutter? It also looks like it could open it too.

Be careful when reinstalling it to not over tighten the screws, you can damage the sensor. Personally I'd leave it alone. You can pull the carriage out from the service station and pull the shutter open to ensure it isn't stuck, and close it again. What you described about a lot of lint there is typical, especially if they're using media with a high rag content. But that shutter keeps it from fouling the actual sensor. If I was going to clean it I would pull the carriage and not just the sensor.. and get at the entire underside of the carriage. Plus then you can open the shutter and inspect the actual sensor.. to make sure nothing is blocking it.
And a note about removing the carriage; you don't have to disconnect the trailing cable at the carriage or remove the tube assembly. Remove the two T-10 screws that secure the trailing cable at the middle of the printer, and you can pull the carriage out with the cables and tubes attached.. flip it over and clean it. Saves a lot of time and the wear and tear on the end of the trailing cable.

Kiran,
After looking at those pics of the shutter ope and closed, I can't recall seeing it in the open position.
I need to take it out for cleaning and make sure it opens smoothly.
And thanks for verifying the 32v for the carriage voltage. I feel better now and will sleep better.
Thanks

The manual is apparently wrong. Another Z3200 gives the same result of 32V.

Re: HPDJ Z3200ps photo printer with Error code 79:04 44" model
Yes, it's reading the encoder strip but you've still got some odd carriage position problem if it's not picking up the cutter correctly. And if it's not picking up the cutter, it may also not be opening the color sensor shutter. Run the test again and watch for the shutter being opened.
Make sure you've run the service station diagnostic test too.
I'll ask about the carriage voltage. It could be correct and the manual is wrong.

Re: HPDJ Z3200ps photo printer with Error code 79:04 44" model
No I have not ordered another encoder yet. I'm hesitant to do so after today. It has to see the encoder otherwise the prints would not look so good, correct?
I would be interested in that color sensor.
I will go back and remove the color sensor and clean it and make sure the shutter is working or at least not sticky with ink.
I kinda wish I had just left it alone after cleaning the lint that was stuck on the right hand side of the carriage. But the customer told me I was the first
to look at this plotter in years. I could see it would've been long before the belt was an issue and the svc station looked bad with lots of ink on it.
So I thought to do the maintenance before it broke. Opps.
So what about the carriage voltage? It reads 32 volts and the book sez 43.6 to 46.3. Is this not a problem?
Thanks

Re: HPDJ Z3200ps photo printer with Error code 79:04 44" model
I wouldn't worry about #1.. the version of the carriage is probably newer than the manual.
#2 sounds like you've got a bad spectrophotometer/color sensor. I had a bad one; you could see it didn't produce the color blue during the test. Being it's a $900 part.. you might consider living without it, unless color is extremely critical. You might find a complete used carriage for less, too. You also want to make sure that the shutter on the color sensor is open during the test. With your carriage position problems, it may not be getting opened.
I actually have a used carriage from a Z3200 that the PCA was bad on, but the spectrocolorsensorthingy should still be good.. if you want it.
#3 79:04... eh. Test probably wasn't programmed correctly.
Did you ever replace the encoder strip?

Re: HPDJ Z3200ps photo printer with Error code 79:04 44" model
I spent some time on this to double check things. I ran the carriage test from diagnostics. Here are the results.
1) the carriage pca revision is 2.313 The book sez it should be between .0823 and 1.005. Pressing back/cancel did nothing but I could
select "No". Then the test continued.
2) everything was fine til it got to the ESP sensor. It gave me this information FW Revision V4.080D, sensor type GE3, serial # 262, & mfg date 1049.
I enabled the sensor and it eventually gave me the error of 58:11, Delta E out of limits.
Next I re-ran this test and selected "No" and it displayed error 58.4:11
58 refers to the color sensor and 11 sez clean and re-seat adjust etc.
3) I ran the test with the color sensor disabled and it gave me the firmware code 79:04
The thing that are different this time is when it moved to the middle, 1) it did not ask me if it was in the middle and 2) it actually stopped in the middle
of the paper.
The customer has been able to get some really nice prints off of it but still has to run the cutter manually. Also it gave them an 87:10 code.
For this I got some compressed air in a can and cleaned the sensor. He ran a large print that came out really good. No bands or jagged lines.
What do ya think?
Thanks
