Hello, I have been working on this for a long while. This machine ran great then started producing unfused copier. It will shoot out a few good copies the starts getting worse. then occasionally shoots out a few good copies. There is no problem with Black and white copies. Just on color. I replaced the FK 8506 IH and the IH Box assy and the Fuser. Not sure what to replace next. What I have done has had no effect. Any help will be greatly appreciated (Pics Attached) THANKS !!!

Re: Taskalpha 3051ci Problem with not fusing
It's only not fusing the process black areas which are 4x the density of other areas. I'm assuming you're using OEM toner, if not that's where I would start. Also assuming you're using standard 20lb paper ? If that's the case, have you tried bumping up the fuser temp a little ? -
Re: Taskalpha 3051ci Problem with not fusing
Is it safe to assume that it's Plain paper that it's happening on?
It's really really unlikely, but I had an intermittent fusing issue a while back ... and this is it:
First & second pages with heavy coverage exceeding 200% fill draw toner from the paper in two bands 35mm & 13mm toward the center of the page. The following pages pick up residual toner from the fuser, clearing up within 5 pages. The effect is worse on glossy linen "certificate" paper (97gsm), KM-4551ci.
Cold areas present as chipped areas where heaviest fill is present. Hot areas present as shadow images through areas without fill. Tried IH coil, fuser, increasing fusing temperatures in U161: Warmup > Ready (Center) = 173 [default: 165+8] > Drive (Center) = 177 [default: 170+7] > Wait (Center) = 173 [default: 165+8] > Print > Full Speed Print (Center) = 177 [default: 170+7], decreasing fuser temperatures by 5C on same U161 settings.
Temporarily enabling Silent Mode minimizes the issue. Set Plain media to Normal2 & Certificate media type to Heavy1. Remove 375W battery backup in-line with the copier. Remove additional 375W battery backup on the same line but connected to nothing. Restore U161 fuser temperature defaults.
=^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: Taskalpha 3051ci Problem with not fusing
did you ever run any adjustments?
U140? U464? U410?
What do you see on service status page for coverage last page in case of bad copy?
Have had several systems with printouts like yours, because of not running adjustments.
One more time i must ask for U000 data, because 3051 would launched in 2013.
We do not know the counters or the age of the system and components.
Does it calibrate or not, does all adjustments would done or not.......this all will be visible on U000/ allComment

maybe you could share with us mind readers what you have already tried to do to fix this?Comment

Re: Taskalpha 3051ci Problem with not fusing
Are you running a heavy paper?
What are the current setting for U161? The default is 165c for this model.
Have checked the heat roller for defects or stuff stuck to the belt?
Have you cussed the machine and kicked the stand?
Details please on what all you have done and observed.
ThanksComment

Re: Taskalpha 3051ci Problem with not fusing
Looks like that has fixed it so far. Seems to run without a problem. I went through the U161 settings and set them to the specs (several were off, Low power was set at Mode 2) I calibrated it U464, Halftone U410 is not completing, I am getting S001 Can't find patch. I tried running patch through bypass and moving it around on glass. Siill no luck. So far so good though. Thought I would get a new transfer belt to sharpen up the patch and try again Thanks for your help !!!Comment

Re: Taskalpha 3051ci Problem with not fusing
Check U465/ Stress for front and rear basic values.
There you can see the condition from belt surface.
For good/ new one there are values around 2600 for both
In case of bad/ broken one the values are less than 2000
Also check event log for C76xx hidden calls. You`ll never see C76xx o0n the screen, only logged internal.
At least you can compare U464/ Target value against U465/ Bias Calib
Target values for CMY are nearby visible in Bias calib after running U464/ calib (BK not identical)
If 1 or more are closed together, you know the belt surface is not the problem , if you get a diffenece from 30 or more for 1 or more colors you has to search for the reason.
e.g. exchange from the related dv or dk.
You also can run test copy in case of U100/ Set AC Auto Adj to "OFF" instead of "ON" (system will work with initial values instead of calculated values) for checking unit conditions.
ONLY for testing, you has to set back to "ON" after testing!!Comment
