How do I clean the rollers on a laser printer that won't feed paper?

The laser printer rollers get dirty with toner and dust, so you need to clean them with a soft cloth slightly dampened with distilled water (not soaking wet!) while the printer is off and unplugged. Gently run the cloth over each roller, rotating it by hand if you can, and be careful not to press too hard because they're fragile. If the paper still doesn't feed after cleaning, it could be an actual mechanical problem and you might want to contact support, but usually just removing the accumulated dust does the trick 🖨️

Before cleaning, check if the paper isn't just jammed in the tray or if there's something stuck inside - happens all the time that people rip out the rollers right away when the problem is simpler. If it really won't advance, a cloth with distilled water works fine but make sure the rollers spin freely while you're cleaning - don't force them. Sometimes the issue is the pickup roller (the one that grabs the paper from the tray) more than the feed rollers, that one tends to get dirty even faster.

When paper doesn't advance, the problem is usually that the rollers have gotten sticky from dry toner buildup - a damp cloth won't cut it. What actually works is rubbing each roller with a cotton ball soaked in isopropyl alcohol (the stuff you use to clean camera lenses), going round and round, until you don't feel that sticky resistance anymore when you manually spin it with the printer off. Dry toner comes off way better with alcohol than water, and alcohol evaporates right away so you won't risk damaging the electronics. After that, wait a couple minutes for everything to dry before you power it back on.

If the paper isn't advancing at all, the problem could also be that the rollers are clogged with hardened toner - in that case a damp cloth won't cut it and you need to scrub more firmly with isopropyl alcohol (the stuff we use to clean screens), always with the printer off and unplugged. But first make sure there's really no crumpled paper stuck inside or some basic obstruction, because that happens way more often than you'd think.

I used to have a printer that did exactly that - paper wouldn't advance even a millimeter 😅 Turned out the problem was a combination of things: the rollers were really dirty with dried, crusted toner, but there was also a little piece of paper stuck inside the mechanism. I removed everything I could reach, then wiped the rollers with a slightly damp cloth (distilled water, not alcohol because I was worried it might damage the materials) and after a couple of tries it started working again. The important thing is to be patient and try the simple stuff first like checking the tray properly, because sometimes you don't even need to take it apart that much 🐱

Never use tap water or regular wet wipes, because they leave residue that will make the paper jam worse. And don't rub the rollers while the printer is on - it's dangerous and won't help anyway.

The thing the others didn't explain well is that you need to figure out which roller is the problem. Usually it's the pickup roller (the one that grabs the paper from the tray) that gets dirty, not all of them. Turn the printer on, take a look inside without sticking your fingers in, and see if one roller in particular has a dull or dark coating on it. Turn everything off, pull out the toner if you can get to it without taking half the machine apart, and clean that specific roller with isopropyl alcohol on a soft cloth. Rub it in circles, not back and forth. If it's really crusted up, you can also use an old soft-bristled sponge, but take it easy.

After cleaning, manually rotate the rollers (most laser printers have an emergency wheel) to spread the cleaning across the whole surface. Turn the printer back on, do a test print with regular paper - nothing fancy. If it still doesn't feed, the problem might be in the drive motor, and then you'll need to call a technician.
