I've read a number of stories where the internal board that drives the head is somewhat sensitive to power fluctuations to the point where they burn out.
My advice would be to always put printers on *good* UPSs

You got me thinking about the potential for circuit board damage due to the form of the UPS generated 120-v sine wave. I called APC (I have a 650) and asked about this. Here's what I learned from them:I use a reasonably substantial Cyberpower UPS with my iPF8400 and no problems yet either but certaIn electronics don't like the Square or Pseudo-Sine wave A/C outputs of these consumer grade UPS's. There doesn't seem to be any consensus that they are harmful or completely safe to use. I remember when I was researching this that more than one Canon user attributed their iPFx400 motherboard failure to the power supply but who knows if that is true or not. Certainly any UPS has got to be better than none if you live in an area of lightning, surges and brownouts.Hi Paul,Of course the problem here is that there doesn't seem to be any consensus I can find about what constitutes a good enough UPS. Most of the ones that are even remotely affordable generate a pseudo sine wave at best. How good is good enough?I've read a number of stories where the internal board that drives the head is somewhat sensitive to power fluctuations to the point where they burn out.

Online civility: Before you press 'Post', ask yourself if you'd say that to someone face to face.
I've been using an APC UPS on my ipf6400 for over a year - through several power outages, brownouts and surges. There's been no problems.

I meant to include a URL or twobut cruise Amazon for APC or CyberPower UPSs and you'll see there are at least 2 product lines in the lower end. True Sine is a significant adder but worth it IMO. My last APC SmartUPS lasted 14 years through multiple batteries.

Since it seems likely that you will have to replace the print head soon I would suggest you go onto eBay and order one of the heads shipped from Japan. It can take a couple of weeks to get here but they are identical to the ones you would buy in the US and quite a bit cheaper at around $330 including shipping. I had to replace the right print head on my iPF8400 after only 15 months and quite a bit less printing than you have. Irritating and quite a bit sooner than I had expected but I knew that they were consumables when I bought the iPF8400.Hi Thanks Howard
I guess that answers my question about trying to clean the head manually, I guess I just have to bite the bullet and install a new R head, but I'm going to wait till the old one stops altogether because at present the prints still look fine to me, so unless I get another Hardware Error pop up then I might start to worry a bit more. I'm still a bit concerned what happens if I replace the R head and it still the same? That's my biggest concern as I've printed nowhere near 3000 square meters? only 184? oh well I guess it's because I've been leaving it ide sometimes up to 6 weeks!!! without use. It usually does a couple of clean cycles and a nozzle check and it's was fine
Oh well you learn the hard way.
This is the seller I bought from:Do you have the name of the seller? and was it OK, like Genuine Head and worked ok?
Thanks
