[tec966]

Good morning,
we ask you if you have any suggestions for the attached problem (white vertical stripes)?
You can see it well in full solid colors.
We have already replaced these parts:
all the dev unit and drum unit
LSU
HVT Board

Thanks in advice !

Heads-up: 7353ci CQ light bands OOB or after service

Re: 6053ci Print issue

did you run the maintenance modes afterwards? so that it knows it has new parts. did you run any calibrations?

Looks like gear lash from worn drive pack.

Run U89 grey print of cmyk and see if pattern is less prominent in K vs others. (Different drive motor/gear train)

Re: 6053ci Print issue

Looks like wrong DV voltages.
All needed adjustments would done?
Please share U000/ maintenance report (*.txt file)
Check U140

Thanks for your reply, the thin vertical lines are both on colors and gray, we did a U021 reset and all the MK adjustment...(U952 etc..)

Perhaps Paper drive is affected and not image drive.

Waste toner auger is driven from PF drive. Check for build-up or difficult rotation of auger drive gear where PF drive engages, the WT clogging is common issue.

The issue is visible on the belt, so i think is not a papre feed problem...

Re: 6053ci Print issue

It is difficult to analyse from the shared picture.
Please share U089/ color belt + U000/ maintenance report.
If i would called for help, i always ask for reports and internal printouts..
What do you think why it would implemented from japanese engineers?
It's easier for analysing problems like yours.

Good info to include in original post (panic stop observation), this is in area before transfer operation (underside) or after transfer (topside)?

Get those U89 samples and Maint. Report. (Help us help you)

Still, check Waste toner bottle to insure it rotates while engine cycles with WT door switch cheated. Common issue of WT bottle non-rotation can clog TX belt cleaner as well as rear auger.

Ensure TX belt setting procedure is performed (MM469 Belt Initialize)

Oh my goodness yes and thank you for your post. In my previous post I mentioned 'Gear lash' but didn't really explain it in context. It is a tiny delay in speed as the force on each gear tooth varies through it's rotation.

So, most of your are familiar with those big round metal disks they have on many copier motors involved in driving image components?

Well, not to steal a Star Trek phrase, but those are 'Inertial Dampeners' designed to help motors overcome uneven torque loads in the components they drive.

Well this series has none and uses drive packs for color DV/Drums with plastic gears and can be a bit cloggy in the waste area, all leading to some rather less than even driving. The TX belt shares drive with the K DV and so a K problem can effect the TX belt and so forth.

New components can be a bit stiff, or clogged ones can become tougher to drive, leading to loads which do not allow smooth imaging, and I suppose this is worse with higher speed.

Kind of like us old techs trying to climb stairs with bad knees. (Not to say these machines are like that)

If it's new, break it in. If it's old, clean it. If it was rebuilt, reseat it. If you must lube, stick to gears driven off the pack or motor only and get (PN 7BG010009H GREASE MOLYKOTE EM-50LP 50G) Lubricate EM-50LP on gear in case of noise.
