Phaser 6510 ghost image repeated at 2.75"

[LongJohns]

I changed the paper type on the settings page and that seems to have solved my problem. I am guessing the fuser wasn't as hot as it should have been.

I guess I should have updated this thread.

I am having the exact same issue.  I have not been using my printer long (I bought this in frustration with HP printers which were always giving me problems.  sigh). So far, I have only printed 1,972 pages with it, so if I would be suprised if I have outlasted the life of the fuser,   What I have found is:

• If I only print a single black and white page at a time, its ok.
• If I print a long print job, it starts showing up.
• If I print a larger colorful graphic, I will always get this, even if it is a single page.

This is rendering the printer kind of useless.  As I am starting to rely on my Inkjet printer if I have a serious print job to do, which is exactly the opposite of how I was expecting to use this printer that cost a multiple more than the inkjet. If anybody can offer any suggestions I would appreciate it.

I did not detect any offsetting of other colors in the recent pic that you uploaded. But you said you see some, so that is the assumption.

The only other cause of repeated image (or similar) would be from the IBT, but it does not usually look like this. Especially a defect that repeats every 2.75 inches. If the frequency of this defect is consistently 2.75 inches, then this is most certainly not being caused by the IBT. And if you are seeing multiple colors that are offsetting, the only logical thing would be the fuser.

The transfer roll is usually not an issue. It can last the entire life of the machine without replacement. And the discoloration should not affect copy quality. You should not have to do anything to it, and really shouldn't try to clean it (you could actually cause an issue if you do).

Based on the evidence that you have presented, I would also discount the transfer roll.

I'm not sure what the normal (actual) average life of the fuser would be on this product. I do know that they will eventually fail, and must be replaced. I just don't know when that will be. I'm sure it varies from one machine to another depending on usage habits, media type, etc.

From a remote diagnostic perspective, I feel that the most likely cause is the fuser. Offsetting is caused by small amounts of toner sticking to the fuser rolls as the paper passes. This causes that toner to be transferred to the paper further down the page. And by the end of the job, there is usually very little evidence present on the fuser rolls (until the issue becomes severe).

There is less than 10k prints on the fuser, claim is 50k.

Yes, standard 20lb paper.

It only started doing this, we have not change paper brands, doesn't always do it. Always will do it on page 2 and 3 of a 3 page bank statement. Fuser looks ok, not dirty. Transfer roller seems to be fairly dirty though. any recommendation on cleaning it? So far I have just wiped it with a micro fiber cloth.

link should be fixed.

Sounds like a good bet to be the fuser. If it is the fuser, then the term used for this defect is called offsetting. But offsetting is less common these days (than years ago). How does the suface of the fuser rolls look? Any idea how many prints the fuser has on it (current life of fuser)? 

I had assumed that this was being printed on regular 20lb paper... is that correct? If it's heavier than that, then this could be caused by an improper paper weight setting. Although that would more commonly result in toner that rubs off the page as well (in areas of high toner coverage).

The last link did not work for me... said that access was restricted.

That is a scan, here is another scan at 600dpi. It is hard to tell in the scan, but there is red and blue ghosting as well around "Periodic Rate". It is hard to tell in the black areas, but it looks just black.

Pulled apart the fuser, and it could the fuser roller as it looks like it has a diameter of about 20mm which would give it a diameter of around the 2.5" mark

While on the topic, where can I find a list of the part numbers for this printer (fuse, transfer roller, etc)?

[andymbody]

My first thought was the fuser yes, but... It's hard to tell from the example... 

Is this example a scan of the copy or a picture taken of the copy? The toner of the bar looks brown (combo of CMY) rather than black. The reason this is important, is because you need to determine whether this repeated image is in a single color or multiple colors (C, M, Y. K). If multiple colors (not just black), then the issue could very well be in the fuser.

You measured the distance between the defects as 2.75 inches. That would point to a component that was about 22mm (7/8th in) in diameter. (distance divided by 3.14 (pi) = diameter). That could be the size of the fuser roll, but I don't have this printer to check. But this size could point to other things as well, so determining which colors are being repeated is probably a better clue.

Hmmm, seem to be having issues uploading images here, so I placed it here: https://drive.google.com/file/d/141MXXQIoPvff0dFBCiroNKDpzI6V_XF9/view?usp=sharing

Now I am not sure, but could this be something with the fuser? Something that is at least 2.75 inches around.I am nt sure how the fuser is assembled on this unit if it uses a film vs 2 rollers.

Of course it starts doing once the warrenty has expired... ;) lol

[andymbody]

Can you post an example so we can see the defect?

[LongJohns]

We have a Phaser 6510 and when we print a statment per say with a solid color bar, a ghost image of this bar will be repeated (once) at about 2.75" down the page.

If an engine clean is performed it will be good for a few more prints, but will return shortly after.

Suggestions?
