Printer Help! Pics attached

So I Just bought a second hand hp laser printer on adverts. It has 2 issues.

1: There is a yellow line on the right hand side even when I print in black and white. It's usually less strong on the second and 3rd page etc.

2: there's a smudge mark that I keep getting on pages too in roughly the same place each time.

Anyone got any ideas to what the problems are and if they are easy fixes?

Model number of printer would help. Maybe yellow toner faulty and image belt I think the call it. Again depends on model maybe picture of it also may refresh our minds

The smudge is always the same shape and size on the left of page but moves up and down the page. Some pages don't have it.

the yellow line is really only on the first page and pages after it don't have it.

Thanks for the help

Looks like the yellow drum is kaput.

Can you take out the yellow toner cartridge push back the cover and see if there is any damage to the drum?

Do you think the yellow toner could be cause the smude marks too even when I print only in black? I suppose I'm getting yellow lines printing only in black anyway, so it may....?

I'll order a new yellow toner. This one is only 20% so it could be dying at the end of its life.... I just didn't want to commit more money to this in case it doesn't work.

Sorry just saw your reply. The Yellow toner cartridge is causing one issue.

That's not your only problem though from this pic it looks like the black toner has damage as well from this pic. Check the same I think it has drum damage.

And this looks like it could be the transfer belt which can be checked for damage with a visual inspection. I don't think its the fuser unit but can't be 100%.

If the transfer belt and\or fuser need replacement as well as 2 toners you might be best at looking at replacing the whole unit. Not sure the age but other parts like rollers, separation pads etc. will all start to give trouble. Colour lasers are expensive to run.

UPDATE!

Anyone any ideas on how to tackle this?

OK so I replaced all the toner and I still had an issue on every second page on the same place. I have now found this (pic attached) it's a label stuck to the inside of the printer. its under the toner cartridges and difficult to get to. Is that part delicate? what is it called? can I clean it with alcohol?

Edit:

Took it apart and cleaned with alcohol. working perfectly now :)
