I have found Increased suction only works during the loading of the paper. You can easily hear the machine ramp back down as soon as the paper loading process is done. This is true at least on 9880 and 9900, can't speak for sure on the 11880 but I figure it's the same.

If the increase suction was working during the print, you would hear the louder noise of the fans during the print and as soon as the paper is finished, the fans ramp back down.

I dealt with this issue on Epson HotPress Natural.
The solution from Epson's East Coast specialist after 2 D1 techs replaced everything. Some parts twice.

Platen Gap has to be set for Standard. Run the job at 2880.

Frustrating and not a perfect fix, but it did solve the issue in areas with heavy ink coverage.

what do you mean by everything? even headblock ?

Very much the same experience a friend had some years ago with his 11880. Uses it still in that setting when he can not do the (repeat) job on his iPF9400 that does all jobs in any print resolution setting and way faster then.

I find this very interesting.

As the mention of hot press natural. See my thread "7900 headache" I had no problem with my printer until loading it with a roll of cold press natural and it seems to look like the same thing only yours (i am sorry to say seems to be worse).

I have got mine better with head alignment but still thing something more is wrong

Hope you get it sorted

I finally found the problem: UPS! after about 2 months of Epson technicians coming and going, talking pictures from the faulty print sample and send them to all the world for help, they decided on changing printer main board that maybe a chance to solves the problem. meanwhile quite by chance, I had my UPS battery changed; the guy who were changing the battery was keep telling me that UPS is not good for laser printer and while I was keep telling him that this big printer is not laser one, he was repeating himself all the time! when he did his job and changed the batteries, I tought maybe because of old corrupted UPS batteries, when I was printing 60" because of high suction drawing lots of current from UPS, UPS couldn't have supply enough current to printer. I bypassed the printer and conect it to outlet directly; to my surprise, the problem solved. I tried and tried several times with 60' paper but no problem at all. again, I run the printer via UPS but this time with new batteries, again no problem!. God knows how happy I am. I informed Epson of the matter, but not any feedback from them since yesterday that I have informed them. anyhow, thanks everybody here who tried to help me. change your UPS battery sooner than later!

Ali, thanks for the update, makes sense now that we know what the issue was, glad to see you finally have it sorted.

Interesting is Epson QUALIFIED PERSONEL(!) could not even guess what is the problem and order for new main board one month ago and even after one month, Epson Japan could have not provide them a main board; they said they have to order one to the vendor and we don't have it in stock! Assume that after another month waiting, Epson would change the main board and still there was a problem, then what else Epson wanted to do?! change the head block? Epson support is really ridiculous, really shame on them, I don't know if it is the same with Canon printer or not.

"Epson support is really ridiculous, really shame on them"
+1 on the above.
Sorry your having so much trouble-hope you get it worked out
Recently I had to take my R3000 in for service,out of warranty,so,I payed.
You wouldn't believe what the owner & his son,had to say about Epson tech support.
Half of all the printers that he had to service were Epson's,mostly for the same issue
And,After dozens of e-mails to them,they refused to make any changes to the ink clog problems
On some of his e-mails,they didn't even bother to send a reply.

Thanks to these guys {Aldito's Repair,LI,NY},my R3000 is working perfectly

Why are you blaming the support techs for something in your environment about which they have no knowledge or control?

They have to make a basic assumption that you are connected to a functioning, working, power supply (be it UPS or otherwise). You know what happens when you start telling customers that the reason their product (any product) isn't working is because of the environment or some other piece of equipment they are using? 99% of the time they get defensive, upset, angry and start telling you to take long walks off short piers.

It's a lose/lose situation, so without clear evidence (like a UPS that's screaming because it has a fault), they have to assume it's something wrong with the printer. It sucks, and perhaps you wouldn't have reacted badly to being told it might be something else (and sure, there are good ways and bad ways of going down that path) but at the end of the day, it's the responsibility of the user/owner to ensure that everything else is up to scratch before calling and saying "hey, I think your product is faulty, please come and fix it".

That can be very difficult, we're most of us not experts in these things, but these are commercial products and there is an expectation that you have suitably expert advice to call upon.

Honestly I sympathise with the issues and I think your whole approach to fixing it and posting up etc is great - this really isn't directed at you, per se, but I see it so often I just can't let it pass without comment to balance up the view.

This Looks and sounds similar to my problem, I don't really understand what you have done though to fix it can someone please explain to me.

Excuse me stupidity

UPS battery ??

I have an epson 9700

Farmer · « **Reply #32 on:** March 07, 2014, 06:25:00 pm »

A UPS is an Uninterruptable Power Supply. Basically, it's a big battery that sits between your power supply and your electrical device and if the power drops, it keeps the device running on the battery. They do other things (condition the line, protect against spikes, etc, depending on the model) but basically that's what they are.

The batteries are generally replaceable and when they get older they don't perform as well and as a result the power being delivered can be below expectation and below requirement. The reduced power can cause electrical devices, including printers, to fail to operate correctly and can be very difficult to diagnose as an issue (for all parties concerned).

Farmer, support technicians should know about UPSs, without a doubt.

Roger_Breton · « **Reply #34 on:** March 07, 2014, 06:37:08 pm »

What kinds of adjustment do you have on your printer?
Is it like on my 4900, you have to buy a separate adjustment utility?

I am surprised how much I can adjust the printer by.
Seems to me your 11880 can only do "more" than mine?

Farmer · « **Reply #35 on:** March 07, 2014, 06:39:47 pm »

Yes, they should know they exist. But when you tell a customer it's something other than the vendor's product, a lot (most?) react badly, so it becomes difficult. When you say to someone, "hey, the UPS might be an issue" and the customer says, "but it's not beeping at me or showing any problem" they're also implying "hey, are you trying to pass the blame on to someone/something else?".

It's a sad but true fact and it does impact on how techs often deal with these things.

Sure, "disconnect your product from anything and everything and then just get it running bare-bones" should be the first thing to try, but even then customers frequently push back and complain about it or expect the tech to do it and then blame the tech if anything goes wrong with the other equipment

I didn't mean to attack all tech support people-some of them are very good
What I am complaining, about is ,how the the /repair people have let it known,to Epson is totally aware of the issue,and refuse to address it.
It is not just a problem with the R3000,but many much more expensive models,with maybe an exception for the 3880?

Farmer · « **Reply #37 on:** March 07, 2014, 06:52:49 pm »

Everyone is entitled to report their own experiences, so your comments are absolutely valid, Mike.

It's usually not nearly as crystal clear or obvious as people think, though, when you start dealing with entire populations of products around the world. A problem to you may be statistically non-existent to a manufacturer. Of course we know and have all heard of situations in which known problems were denied. There are many reasons for it, not least of which the overly litigious nature of some groups these days which has the net effect of making corporations say nothing when they might otherwise be quite happy to discuss something to reach a conclusion. Sometimes, of course, it's just very bad decisions from management.

For every reported "customer service failure", there are almost certainly 40 or 50 satisfied customers who never comment publically (because they're happy). That doesn't mean you shouldn't complain about bad service, it just means we should avoid drawing too long a bow. Once again, data is not the plural of anecdote :-) But you should still tell your story for others to know and be aware.

I'd like to know just what kind of UPS you have. In a standby UPS system the printer is powered directly by input mains and the backup power circuitry is only invoked via relay when the utility power fails. The condition of the batteries is moot unless you have some weird setup that is using the clipped sine wave output of the UPS all of the time and you've somehow disabled the alarm. Regardless, the Epson tech needs only to scope the input to the main board to determine it's "cleanliness" and suitability for the purpose of running the printer. This test should always be performed immediately after the classic "on/off" switch test. - Jim

I agree. There are some which work differently, but the majority just pass standard AC power unless it drops and then switch to the battery. Most UPS backups work for years and in many of them the batteries are worthless and people still keep using them. I pulled some out of a location that were so old I couldn't even find replacement batteries, and the batteries in the would keep the computer up for about 10 seconds ... very dead. Worked fine until the power actually went out. Some have alarms or lights to warn you when the battery needs replaced, but those seem to be pretty unreliable as well.

I don't think any technician for any company would think about a battery backup to be a problem in such a unique situation where only 60" paper is a problem. They're not engineers, they just trouble shoot they way they've been trained. I'm having a hard time believing it myself ... don't misunderstand, I believe what you are saying, it's such and oddity that no one would ever think of it and it's certainly a very unique situation. I don't know why the printers power consumption would change much because of the paper size and how in the world that could actually create lines on the paper. Certainly a very weird circumstance. Lucky you stumbled across it.

I see these UPS for printer threads and I guess I'm not quite seeing why. I suppose if you live somewhere that gets hit by frequent brownouts or power bumps all the time maybe, but where I live if the power dies, I"m done for a while. My backup keeps my computer on long enough to execute a safe shut down. Yeah I might lose a little paper, but I think you would be better off investing in a very high quality surge protector, instead of a battery backup.
