Canon Imageprograf 780 " replace printhead" message

[copiertec]

We have a client in a remote location with a ImagePrograf 780 that just came up with the message "replace print head". Is there a way to reset the message without changing the print head? Or does it need replacement PF-04
in order for the message to be reset?

No, if it indicates the code or the message it must replace.

+1 GUI is correct.

please tell us the are using genuine Canon Ink. 3rd party ink is KILLING these machines. Notice other ImagePrograf threads.. one user REFUSES to use OEM... got rather heated about it.. said he found a 'china reset device' don't think those work and could cause other issues down the road.

There were supplies of defective printheads that also went away with original inks, there is a procedure for warranty replacement of the ipf printhead within one year after purchase.

Thanks, Phil. I am assuming, yes on the genuine ink, they are not on a service contract, but we have insisted they only use OEM inks. I think I seen that thread where they were arguing about using OEM's just recently.

Thanks GIUBOSS, however, it is past the 1 year warranty. The printhead sure is not cheap, that's for sure.

As Phil mentioned there are previous threads regarding print heads going out - because I "introduced" the idea of reset devices into a thread about a week ago, I thought I would weigh in - yes they do work unless the head is totally "fried" - Is a reset the correct fix? Probably not as to flush the lines and restart with 2 new heads and genuine canon ink would be the recommended fix - that was the way I was trained many years ago - in todays economy the concept of fix seems to have changed to what can be done so the customer can afford the repair, keep running and keep the machine rather than switch to another so called better brand. I agree tempers are flaring as customers/owners are seeing their company health and savings slipping away - My thoughts have always been, both when I was servicing and now as an owner, To do right by the customer - I know, alittle naive - good luck

Re: Canon Imageprograf 780 " replace printhead" message

I am going to step in a bit here - just my 2 cents - since I am staying home like a bored panda.

When a head replacement message pops up (in most cases) it is due to lack of printer usage from customer.

The other cases, when customer is really using the printer a lot (long printing hours) - 2 things happen:
1. The head REALLY performs well with high mileage
2. The customer is happy on the performance and does not think twice on the head replacement costs.

Sadly most customers fall under "Low usage" category...

Now, to advice these customers on using (head resetters, 3rd party ink, etc) - I don't know if it makes sense because they are under-using their equipment already.
If they take the route of resetting and non-OEM, they will find them self in a world of refilling and resetting which may look like "profitable" in the beginning, but it is on worth it.
The only category of customers where compatible ink would make "some" sense - would be high volume users, assuming that their Chinese ink producer is a decent businessman and produces "good quality" ink to some degree.

But print-heads !!!
All the refill guys I know - none of them tampers with print heads
1. because the risk of frying boards is very high
2. because of the head cost / m2 is very low compared to ink
3. because if you are high volume printer you can't afford to waste time and media and ink if the "re-setted" head is not performing as it should.

I am not trying to be harsh and dis-respectful on anyone here... it is just the way I see it (which may be wrong by the way)

Peace....

So far I have not had much luck with this argument, though I agree 100% with everything you've said.

Have you come to any conclusions about the absolute minimum print volume? I've documented endusers running 24 ft2 per month that manage to avoid the typical head errors, AS LONG AS they print at least one Arch "D" full color each week. =^..^=

Re: Canon Imageprograf 780 " replace printhead" message

There is not a "Right" number - as you already know

Usually I advice the same :
1. Keep the printer ON while in office
2. Print "smth" 2-3 times / week

Cheers

Re: Canon Imageprograf 780 " replace printhead" message

I drove out to the client yesterday, 214 mile round trip. When I went out there, the PFI-107 Matte Black Ink was empty, the client failed to mention that, so I was unable to do anything because the ink is totally empty. So, we are going to ship it out to them so we can get to the next step. The client mentioned that they have been running the machine with the low ink and would turn it off then on to get it to print. So, I'm wondering if that would cause air in the printhead causing the printhead replacement error.
Customers really amaze me! I was a little pissed as I drove all the way out there and they failed to tell the front desk they were low or out of ink! I explained you can't jump to B without A first. So, once they install the Matte Black ink, they will call us if the printhead replacement message comes back up.

Re: Canon Imageprograf 780 " replace printhead" message

Make sure that the firmware is upgraded...MANDATORY on all Canon wide format printers. Old firmware will cause boards to fry(main,carriage,etc) when the head gets too old and shorts.

Re: Canon Imageprograf 780 " replace printhead" message

Thank you, Canuck, the firmware is up to date. As I have mentioned, I drove out to the site and the matte black was empty, customer just repalced black ink. I installed the matte black ink and have not heard back since. The problem is that the matte black ink was out and the customer just kept on turning off the machine and restarting it because, they said when the they turned it off and on, it would print a page or 2 then error out. I think the head was getting overheated possibly and causing this error. So, no call back yet for the printhead.
I explained to the client in a straight forward manner and told them not to be a bunch of idiots and replace the ink if it needs to be replaced, open your eyes and read whats on the display, out of ink means replace it. Bunch of over educated engineers that talk about quantum physics and string theory but can't read English.
