Ink Streaks When Printing

[OnlyNothing]

Hi,

I have the 

HP LaserJet 700 color MFP M775

The issue is when printing, there is a ink strip along both sides of the page. I read up it could be the fuser, and to clean it i would need Isopropyl and cotton buds, but wanted to make sure 🙂 

I tried to make a scan of what happened but they do not show up on the scan.

Please let me know 🙂

Usually, alcohol is not a strong enough solvent to remove baked on toner from a HP fuser film. It could also damage the fuser rollers or cause the fuser film to seperate from the pressure roller. I would not recommend doing that just yet. You can actually remove the fuser from this printer, open up the jam removal door- and just visually inspect the fuser rollers to see if there is a dark strip that would account for your problem. With the fuser jam removal door open, you can hold your sample up close to the rollers and see if their is a matching stripe on the fuser rollers.

Is the stripe one color like black or magenta, or does it look like waste toner (which would be a purplish brown color)

I would more likely suspect a failed imaging drum, or failed cleaning blade on the transfer belt. If you do a supply status report from the admin/report/supply status page- what does it show your life counts at for the fuser/image transfer unit/ and imaging drums? If you could take a pic of the samples with your phone it may be easier to post. When you gernerate internal reports directly from the printer, is the stripe on the edges of those pages?

This could also be a driver issue, where an oversized image is being sent to the printer.

Hi There,

The colours are different, but mostly they're black strips.

I took some pictures below:

Printer Supplies Status Page:

I printed out the cleaning page from the device managment tab and it left the strips ( in the picture is the back of the cleaning page )

That looks like residual toner on the transfer belt to me. I think the supply status page shows that part at 30%, so will be time time to replace it soon. You can also see what looks like an excessive amount of paper dust on the secondary transfer roller, as well black toner dust coated on that side of the part. I would wager the cleaning blade is starting to fail on the transfer belt (since you mentioned you can see multiple colors) or the waste toner area in the transfer belt is getting clogged up with excess toner.

Are you using genuine OEM HP toners or an off brand? sometimes off brand toners/imaging units can leak at the drum seals, cause toner to spill into the machine and contaminate print outs.

You can eliminate the fuser as a problem easily by just jamming the printer and seeing if the marks are on the paper before they enter the fusing area.

You can use the internal "print stop" test- admin/troubleshooting/diagnostic tests/print stop test- and start guessing at times to enter to make the printer stop when you think the paper is about halway into the transfer area.

Yeah we could order a new transfer belt and see how that goes, they're not expensive, and this printer has lasted us a good 4-5 years. 

We are using Genuine HP Toners. 

I printed a diagnostic page from the general troubleshooting section. This didn't seem to have as much marks on this, but i think it was a coicidence . I will see about ordering a new transfer kit, and see how this goes and will let you know 🙂

thanks for your assistance so far, you've been amazing!

I can confirm it was the transfer kit, i took it out and there was a lot of left over ink on there. I will order a replacement  now.

thanks,
