what is " the toner cartridge head "?

have you got the page counts on ALL supplies?

when were they install?

how long have you had it?

sometimes life % isn't that reliable due to age of the parts.

how about uploading examples of the issue?

are you an end user?

Is the paper being fed LEF or SEF?

This is a fault with drum, dev, x-fer belt or print head..If you were talking about a 20 year old machine I'd say go for it..but this is pretty new..My advice is to call a certified KM tech..Think you are going to be spending a large amount of money, but this is nothing compared to how badly you can break it trying to DIY..E

I dont want to DIY, Just want to understand what might be the problem, have already called for a technician. just dont want to waste a lot of time keeping the machine shut..loosing business.
i am a mechanical engineer by academics. so always thrive for problem solutions and knowledge.
Thanks for the reply.

Since the yellow bars are through the voids and at about drum interval, I'm going to take a WAG that it fed SEF (short edge feed) and that you've got a primary charge loss situation. Most likely you'll have to replace the yellow imaging unit.

But first: Confirm that this page was printed LTR-R, SEF. =^..^=

image unit = drum/pcdu or what ever is applicable to your unit.

for you... drum

FYI... the 'end caps' on the toner IMHO would NEVER give this type problem. But 31yrs in industry, what do I know?

can the toner be a problem?
and what about the banding ?or lines?
thanks for the reply

Re: Toner smear,lines on prints..Help!!!

You have a color banding (yellow) issue, it could be drum or HVT power supply. less chance of a developer issue based on your samples. Your tech will put the machine in service mode and start printing out test jobs to narrow down the fault..Don't know how old your machine is, but ensure you hear that vacuum running, clogged toner filters can cause issues on this series, but it does look a discharge issue, meaning the drum charge is being fully dissipated in one area as the drum turns resulting in incorrect toner attraction. New machines are modular and the entire drum section will need to be replaced. E

Post consumables life counters and machine counter. From what you described qualified tech should fix it in first visit.
