Laser printer lines across page 🤔
Laser printer lines across page 🤔
Can anyone suggest what causes these lines across the page?
Is a new toner cartridge likely to fix this?
Edit: Line separation is 62.5mm
Edit 2: Thank you to everyone who replied. I've ordered a new toner cartridge and will update this if that solves the problem 🫡
Final update: A new toner cartridge fixed it. It's now printing perfectly! Thank you.
I think your fuser roller may be dirty or damaged. Try printing several pages that are blank or nearly blank. If it's dirty, the lines should get progressively lighter. If not you may need a new fuser.
You can buy a fuser repair kit for your printer model online. They are usually only slightly more complicated than changing out the toner cartridge. Just be sure to lay down several sheets of printer paper to cover your work area to catch any toner dust.
And a word to the wise for anyone attempting home laser printer repairs. Do not use a vacuum cleaner to suck up any spilled toner. Wipe it up with a damp paper towel or something instead.
Printer toner is so fine that it will sail right through the bag or filters in your vacuum cleaner and then get dispersed forcibly into the air. You know how microplastics are a big deal nowadays? That's what printer toner is. With a vengence.
Toner rated vacuum cleaners do exist but they're expensive, and nobody not doing printer repairs commercially will want to spend the money on one.
⚠️ Thank you for that warning (and explanation). I would definitely have used a vacuum if it happened before reading this 😅
after the second or third NOS toner spewing its contents inside a printer, I splurged and purchased a toner vacuum. Cheaper than having the printer tech come out and clean up the mess for me.
as the printer tech explained to me, those NOS toners (at least HP ones) have a plastic piece that wears out when sitting in the box.
The lines haven't become any lighter. Is this a problem I will be able to see if I take the printer apart? Thank you for replying 🙂
You might be able to see it on the fuser roller but it probably won't be the sort of thing you can wipe off without making it worse.
From the model number shown on your test page (Samsung ML-1660) it looks like a replacement fuser kit is about $30 - $50 dollars depending on the seller. I would encourage you to either replace the fuser or look for a new printer.
I think measuring the distance in millimeters will get you to a better idea which part is causing this.
I found a manual that says for toner cartridge: Drum is 62.9mm, Developer roller 35.1mm, Charging roller 26.7mm, Supply roller 47mm
Fuser parts are: Pressure roller 75.4mm or Fuser roller 77.5mm
You should be able to measure from 1 line to the next to see what’s closest. Sometimes they are hard figure out when they are similar sizes but these are different enough it should get you an idea where to start.
62.5mm so hopefully I can just replace the toner cartridge 😁 Thanks for replying
Hmm. In a former life a repaired large size laser printers. We would measure the distance between these lines, and a table would tell us which drum/roller was causing effects like this (it is the circumference).
What is the distance between the lines? In mm please.
