post here & line-up ...i wish to hear from you ...hope is not more than 50...



DUMMIETEK...in search of true performance...

I have many, but the most common is background
on prints you can get rid of it for a while
with dv refresh, auto gray, etc but is comes
back and i have done firmware

Lots of U010 and U011 codes when faxing. Print out a list from maint mode U671.

Do driver issues count? The quick start menu is full of bugs, and I get color optimizer about 1/2 the time.

Seeing some of these units changing color registration seemingly on their own. Customer has not added toner, used any different paper stocks or had any jams or codes and we get a call for blurry copies. When we get on site, the color registration is wacked. It has happened on three units to date. Just wondering if anyone else has experienced this?

There's another post on that that helped me save a sale. It's mostly occuring on heavier fill documents, 30 or more consecutive prints. Here it is: http://dnet-km.com/eve/forums/...21059411/m/120101301

Current Taskalfa issuesOur friendly neighborhood, Kyocera service rep will be in town this morning to work on some of these)

1. Quark v8 from a PC: God awfully slow when printing. Documents can literally take 30 minutes to print, and this is from an 11x17 2 pages. Customer is creating their documents in house in their marketing department. The document is being created on a 12x18 type platform with marks, so when they take take the final version to a print shop so they can trim it down for a full bleed. Customer however when they print it have to do a 11x17 since Taskalfas do not handle 12x18 paper. This conversion from 12x18 to 11x17 just brings the Taskalfa to a grinding halt. This issue has been opened with Kyocera since late May and a month later we have no resolution other than it's being looked at by the engineers.

2. Taskalfa 400 - Straight out of the box. Printed maybe 300-400 copies. Then the colors started fading out on all the copies/prints. We have gone through and rerun all the setups. Reapplied firmware because apparently voltage settings changed from firmware to firmware and they were afraid those settings weren't applied. Spent 2 hours with tech support on the phone. Spent another hour with our Kyocera Tech Rep on the phone. My tech on site also disassemblied the machine because it was acting like no toner was getting used. However we are seeing toner on transfer belt,etc. So toner is moving. Machine is out of the field now. See what our tech rep has to say today.

3. Another Taskalfa 400. We are getting spotting on all the copies. Machine has about 3,000 clicks on it. We replaced the drum units. Continued to have spotting, Kyocera Rep talked with a few folks, lets replace the dev units. Replaced dev units, still getting spotting. So we will see where we go today.

4. Color optimizer as someone else stated sometimes does not work. Installing it and PDF can be another issue. But we have found that if you put the installation file on the root of a drive it installs just fine. If you have it nested in folders is where the problem starts. But again optimizer sometimes does not work.

5. Mac issue from Office 2007, double sided and other options are not in the print driver for some reason. Only affects Office 2007, print options show up in other applications.

If I think of any others will add. It's been a rough couple of months lately.

Do these spots look like doughnuts?

They are pinpoint dots and appear to be solid. We still attempted the AC Calib Magnification fix Kyocera released end of April time frame. Did nothing for it. Still all over the paper.

Neverlaughts,
I had one about a month ago the color registration was so far wacked i had to do it several times to correct colors.

frozentundra? where are you from? I live in Texas and we really dont have that many problems. The most we get is light copies but after running the color optimizer we are ok. I really think it got something to do with voltages. The spots reminded me of the bizhub c6500 , the cyan would leave donut or pinpoint spots . it turned out to be a voltage issue with the dv unit. Take a look under the tr belt and see if you have the spots. One more thing is it all the colors or just one?.

TonerDog for the backround you need the LATEST firmware, you can get it from the FTP site or your rep. It is called 5.1 or 6.0. We have had some issues but have been resolved with firmware, changing the PDL, and training. The only issue we have now is that you cannot default to mixed org. dect.

FTP address please???

We also think it is possibly a voltage issue. We were talking about that last week. We honestly think it maybe the customer's outlet. It's an older church building. Anyone have a recommendation for something they use to measure wall voltage? It's happening to all the colors by the way.

I carry a SureTest (my personal piece of test equipment) with me. It lets you see conditions of the outlet and also the condition of the power to the outlet. Over all a very good tool. You should mainly be concerned about voltage levels, no major fluxuations going on in the 120V supply, brown outs or voltage dips are almost just as bad as overvoltage spikes, you should also look for voltage spikes between the Neutral and Ground. A good electrical system will show a voltage level between the neutral to ground of no greater than .5 volts with minimal fluxuation. We have seen the voltages at some customer locations staying at 2 to 3 volts and spiking to over 5, at this point the customer has to have their power looked at by a professional electrician. The most common cause is that the connector lugs are not properly tightened down. I was present at one site that we were having trouble with random jamming issues on a KM-8030 and we brought in an electrician and upon opening up the sub panel that the copier outlet was wired too we saw sparks fly. The grounding lugs were not all properly tightened down, there are actual torque specs for tightening of all electrical terminations which usually are not followed. The electrician checked every termination lug and found that approximatel 2/3's of them were loose to some degree or another. Once he tightened them all up our problems with that copier have gone to almost zero. The common person will not understand how the power has such an effect on how the copier operates, but if a sensor (or actually the main board) is looking for a change from +5 Vdc to 0Vdc and there happens to be a spike on the Nuetral to Ground of 5Vdc or greater then the change in state of that sensor is going to be no change resulting in a jam or error, depending on what the sensor is being used for. Neutral to ground issues are most commonly caused by older motors on fans or other office equipment turning on and off, but the most common offender are Microwaves turning on and off.

I had a bunch of Falcon IIIs, all in a relatively small complex of industrial buildings, all dropping off the network unpredictably. Just as unpredictably each of these machines might come back online with no action by the IT staff.

I hooked up a Fluke power analyzer. It recorded over 200 events of ground to neutral spikes in 24 hours. Most of these spikes occurred at around 7:00 am and around 4:00 pm.

This customer consistently insisted that all the MFPs were plugged into dedicated 20A outlets. By the time I brought back the event reports from machine #3 they ceased to argue, and started to actually install those dedicated 20A outlets. And my problems vanished into thin air.

hows the humidity? well we know its something to do with voltage to tr roller and tr belt. Did you look under the tr belt for spots?

FYI on all units on taskalfa....

When you replace a unit on the Taskalfa MAKE SURE you look at the piece of paper in the box that it is in. Alot of adjustments you MUST make when You replace said unit. We had a japanese Engineer at our location and he said that not doing the adjustments can lead to other problems.
Just a FYI

We have one Taskalfa that the yellow fades on on the edges of the copies first and then gradually all the yellow fades away. It happens on longer runs and of course looks good when we show up. Copies are not excessive fill, just normal text in color.

firmware and some adjustments to developer bias wii be avaliable soON! SOME DRIVERS ISSUES WILL BE CORRECTED ALSO...waiting for jamming on the finishers Q\a...



DUMMIETEK....we "r" closer to complete quality operation...
