How to Fix POS Printer Not Feeding Paper Fast Guide

Quick Checks Before You Panic

When a POS printer is not feeding paper, your line is growing and everyone is staring at you. Before you assume the printer is dead, run through these fast checks. Most POS printers not feeding are fixed in under 2 minutes.

Basic questions to ask first

Pregúntate:

• Did this start right after a paper change?
  → Very often the thermal printer paper is loaded upside down or the roll is stuck.

• Are any lights red or flashing on the printer?
  → A receipt printer error “paper not loading” or “cover open” will block feeding.

• Did anything just get moved or unplugged?
  → A loose power brick or USB cable can make a POS receipt printer not pull paper.

• Does the printer make any noise when you press FEED?
  → No noise = power or board issue.
  → Grinding or weak noise = possible motor or roller problem.

If you can answer these quickly, you will know whether to focus on paper, power, or hardware.

How to safely power cycle the POS printer

A clean power cycle fixes many cases of a thermal POS receipt printer not feeding paper:

1. Turn off the printer using the power switch.
2. Turn off or close your POS app, and if possible, restart the POS terminal or PC.
3. Unplug the printer power adapter from the wall and from the printer for 20–30 seconds.
4. Plug the power back into the printer and wall.
5. Turn the printer back on first, wait for it to finish its startup, then open your POS app.

This is the first thing I tell store owners to check when a thermal POS receipt printer is not feeding paper after a change.

2. Clear hidden jams and tiny paper scraps

A small scrap near the cutter can fully block the paper path.

• Open the cover and follow the paper path from roll to exit.
• Gently pull out any torn paper pieces with two hands—never yank.
• Check around the auto-cutter for stuck labels, tape, or stickers.

If your receipt printer is not pulling paper at all, there’s a good chance it’s a mini jam you can’t see at first glance.

3. Clean the paper sensor and feed roller

Dust and paper powder make the printer think there’s “no paper” or reduce grip.

• Use a soft, dry cloth or alcohol wipe to clean the black rubber feed roller.
• Wipe the small paper sensor window near the paper entry—don’t scratch it.
• Let everything dry fully, then press cURL Too many subrequests. again.

A dirty sensor is a common cause of “receipt printer error paper not loading” even with a full roll.

4. Reset the printer to factory settings

If the mechanics are fine but the logic is confused, do a reset.

• Turn the printer off.
• cURL Too many subrequests. cURL Too many subrequests., turn power back on, keep holding until lights flash or it prints a config page (depends on model).
• Release and let it finish.

This often clears weird “no paper feed” or “data” errors that started after a settings change or firmware update.

5. Check paper thickness and roll tension

Cheap or wrong paper can stop clean feeding.

• Make sure the roll matches your printer: 58 mm or 80 mm width, correct core size.
• If the roll is wound too tight, unroll a bit and rewind loosely.
• Paper that’s too thick or stiff can cause jams and motor strain.

For high-volume counters and cash register POS setups, I always recommend approved thermal paper only—random low‑grade rolls cause most feed and jam complaints.

6. Test with a different roll of thermal paper

If nothing above helps, assume the roll itself is bad.

• Try a known good roll from another working POS printer.
• Confirm it’s thermal paper cURL Too many subrequests.

   • The paper should advance smoothly and cut (if auto‑cutter is enabled).

If the paper doesn’t advance, reopen the cover and recheck orientation.

Correct Thermal Paper Roll Orientation So It Actually Feeds

Wrong orientation is the number one reason a thermal POS receipt printer is not feeding or prints blank receipts.

Use this simple rule:

• When the printer cover is open and the roll is in the holder:
  • El paper should unroll from the bottom toward you in most front‑exit POS printers.
  • If you pull the paper and it comes from the top of the roll, it’s likely upside down.

Confirm orientation with the scratch test:

• Scratch both sides of the paper:
  • The side that turns dark must face the print head (usually facing down toward the mechanism).
  • If it faces the wrong way, the printer will feed but print blank or very faint receipts.

Common Loading Mistakes That Stop Feeding

When a POS printer not feeding issue shows up right after a paper change, it’s usually one of these:

• Upside‑down roll

  • Paper prints blank.
  • Feed may work, but you see no text or graphics.
  • Fix: Flip the roll, scratch test again, reload.

• Wrong width roll

  • Roll too wide: paper rubs the sides, jams, or won’t drop into the holder.
  • Roll too narrow: paper shifts sideways and gets stuck.

• Press or pull the top cover lever/latch to open the lid fully.
• Remove the paper roll and set it aside.
• Use a phone flashlight to check the whole paper path:
  • From the roll holder
  • Across the thermal print head
  • Through the feed rollers
  • Out past the auto cutter and exit slot

If you manage multiple outlets or high‑volume environments, make this inspection part of your regular POS hardware routine—just like you would when checking new POS hardware for high‑volume retail.

How to Safely Remove Stuck Paper

You want the paper out, but you don’t want to damage the printer:

• Do not use metal tools (screwdrivers, knives, scissors).
• Gently pull torn paper in the normal feed direction (forward, toward the exit).
• If the paper is wrapped around the roller, rotate the roller slowly by hand while pulling.
• Remove all tiny scraps, especially near sensors and the cutter area.
• Never yank paper backward through the thermal head; that can misalign parts.

Take your time—forcing it is how feed rollers and gears get damaged.

Removing Labels, Stickers, and Debris

• Blocks the paper sensor, so the printer thinks “no paper”
• Causes skewed feeding and crooked or half-printed receipts
• Triggers fake paper jams and “receipt printer not pulling paper” errors

If your POS thermal printer paper is not advancing, but you hear the motor trying, dirty rollers or sensors are very likely the cause.

Where the Paper Sensor Is on Most POS Printers

Most 58mm and 80mm thermal POS printers (SDLPOS, Epson, Star, Bixolon, etc.) place the main paper sensor:

• Just under the paper path, right before the print head
• Near the center or slightly off-center of the paper width
• In a small slot or hole where the paper sits when the cover is closed

You’ll usually see a tiny black plastic “eye” or lever. If that spot is buried in dust or paper flakes, your thermal POS receipt printer won’t feed or will show “paper out” even when the roll is full.

How to Clean POS Printer Sensors Safely

Use only light cleaning to avoid scratching sensors:

• Turn the printer cURL Too many subrequests. and unplug power and USB/Ethernet.
• Open the cover and remove the paper roll.
• Use a dry, soft brush or compressed air to remove loose dust.
• Lightly wipe the sensor area with:
  • A lint-free cloth or cotton swab
  • Damped with 90%+ isopropyl alcohol (not dripping)
• Let it dry fully (30–60 seconds) before closing the cover and powering back on.

Avoid soaking the sensor or using glass cleaner, water, or harsh chemicals. If you’re running multiple terminals or reselling POS hardware, baking in this kind of quick cleaning between shifts massively cuts down on “POS printer paper not feeding” tickets.

• Turn the printer OFF.
• Press and hold the FEED button.
• While holding FEED, turn the printer ON.
• Keep holding until it starts printing a test page, then release.

If your model is different, check the manual or your brand’s support page. For stores rolling out multiple printers or sites, it’s worth adding this step into your regular POS hardware deployment plan.

What a successful self‑test tells you

Si el self‑test prints correctly and the paper feeds smoothly:

• El motor, feed rollers, sensors, and print head are working.
• Your issue is likely software, drivers, settings, or cabling, not the printer’s mechanics.
• Paper feeding problems that only happen inside the POS app usually mean wrong paper size settings or driver issues.

If the test prints but your POS software won’t

If the self‑test is fine but your POS software won’t print or feed:

• Confirma que la correct printer model is selected in your POS app.
• Verifica la port/connection type (USB, Ethernet, serial) matches how it’s plugged in.
• Reinstall or update the thermal printer driver.
• Try printing a Windows test page or a simple text file.

This is the classic “POS printer not feeding” case where the printer is healthy but the system configuration is wrong.

Using beeps and lights as error codes

Most POS printers use power lights, error lights, and beeps as error codes:

Update or Reinstall Printer Drivers

A bad or generic driver can cause “no feed” or blank receipts.

• Download the latest driver for your exact model and OS.
• Uninstall the old printer in Windows, then reinstall with the new driver.
• Avoid printing as a “Generic / Text Only” device while troubleshooting a feed problem.

Test USB, Ethernet, or Serial Cables and Ports

Sometimes “POS printer not feeding” is just “data never arrived.”

• USB printers:
  • Try another USB port on the PC
  • Try a shorter, known-good USB cable
  • Avoid unpowered USB hubs
• Ethernet printers:
  • Verifica link lights on the printer’s LAN port
  • Swap the Ethernet cable
  • Plug into a different switch/router port
• Serial printers:
  • Confirma que la COM port number in Device Manager
  • Match baud rate and settings with the printer manual

Model-Specific POS Printer Fixes (How to Fix POS Printer Not Feeding)

Different POS printers fail in slightly different ways. When a POS printer is not feeding or your thermal POS receipt printer is not feeding paper, use these brand‑specific tips before you give up.

SDLPOS 58mm & 80mm POS Printers

For our own SDLPOS 58mm and 80mm thermal POS printers:

Common “no feed” issues

• Paper loaded upside down (blank receipts / no paper advance)
• Tiny paper jam right at the cutter
• Dirty paper sensor or worn feed roller

Basic button combos

• Self-test / hardware check:
  • Turn printer OFF
  • cURL Too many subrequests. cURL Too many subrequests.
  • Turn ON while holding, release after 3–5 seconds
• Quick reset (varies by model, check label under the printer):
  • Turn OFF, hold cURL Too many subrequests., power ON, keep holding 10+ seconds until printing stops

If you’re upgrading hardware or adding lanes, we usually pair these printers with our POS hardware bundles with 24/7 technical support so you’re not debugging alone: POS hardware with always-on support.

Other Common Thermal POS Brands

For other brands (Citizen, Rongta, Xprinter, etc.) with POS receipt printer no paper feed:

• Check the label under the printer for exact model number
• Download the manual / quick guide from the brand’s official site
  • Search: “Marca Modelo user manual” or “thermal printer self-test Modelo”
• Look for sections on:
  • Self-test / FEED button functions
  • Paper jam removal
  • Sensor locations
  • Factory reset / initialization

If you’re modernising your checkout and standardising hardware across stores, I usually recommend planning printer models together with your POS refresh so support and parts stay simple. You can see how we approach that in our guide on modernizing your retail checkout system: modern retail checkout and POS hardware planning.

Whenever a thermal POS printer paper jam fix or restablecimiento de fábrica step in the manual doesn’t restore feeding, you’re likely looking at motor, cutter, or board failure and it’s time to weigh repair vs. replacement.

Advanced Fixes When Your POS Printer Still Won’t Feed

When your POS printer is still not feeding after basic troubleshooting, you’re likely dealing with a deeper hardware or setup issue. At this point, treat the printer like critical business hardware: test carefully, document what

Warning signs you should not ignore

When a POS printer is not feeding, some symptoms mean “stop and check” and others mean “stop and unplug.” These are the danger signs I never ignore.

Grinding or scratching noises when trying to feed

If your POS printer makes grinding, scratching, or loud clicking sounds during paper feed:

• Stop feeding immediately – don’t keep pressing the FEED button.

  • Shorted board or motor
  • Failing power adapter
  • Blocked ventilation, causing overheating
• Running it in this state can kill the board completely or create a fire risk. Don’t “let it cool and try again” more than once; treat this as a critical fault.

When to stop trying fixes and call a technician

Stop DIY fixes and call a technician or your POS supplier when:

• Grinding or loud mechanical noise doesn’t stop after clearing visible paper
• The red error light and beeping persist after reload, jam check, and power cycle
• Self-test pages fail to print or look obviously wrong (missing half the page, random blocks)
• There’s a burning smell, visible smoke, or repeated power cut-outs
• Feed rollers spin but never grab paper, even with fresh rolls and cleaning

At that point, you’re likely looking at motor, cutter, roller, or main board issues. Those are parts I don’t recommend you open or replace yourself unless you’re trained or following the brand’s service manual.

If you’re planning a hardware refresh rather than a repair, it’s worth looking at cost‑effective POS hardware that still supports reliable receipt printers and replacement parts, as covered in our guide to cost‑effective POS hardware for wholesalers.

Preventing POS Printer Feeding Problems

If your POS printer is critical to your checkout flow, the best fix is prevention. Here’s how I keep POS printer feeding problems to an absolute minimum across busy retail and hospitality setups.

Use high‑quality SDLPOS‑approved thermal paper

Poor paper is the #1 cause of a thermal POS receipt printer not feeding paper, jamming, or printing faint receipts.

• Always use SDLPOS‑approved thermal paper rolls (correct width and core size for 58mm or 80mm printers).
• Cheap rolls shed more dust, curl badly, and can slip on the feed roller.
• Match the roll specs to your printer: width, diameter, and paper thickness (GSM).

For multi‑lane or chain environments, I usually align printer and paper standards with our broader POS hardware recommendations for busy retailers so operators aren’t guessing what to buy.
