POS Printer Not Printing Receipts? How to Fix Error 8701 & Blank Pages

This comprehensive guide covers every technical fix and step-by-step troubleshooting method you need to get your point-of-sale system back online quickly.

How do I fix a POS printer that prints blank receipts?

If the printer mechanism is making noise and feeding paper normally but no text appears, it is almost certainly a thermal paper issue. Modern POS printers use heat-sensitive technology, not ink ribbons or cartridges.

1. Perform The Scratch Test: Scratch both sides of your receipt paper with your fingernail. The side that leaves a dark black mark is the thermal coating. This coated side must directly face the thermal printhead.
2. Correct the Roll Placement: Open the top cover. Remove the paper roll and flip it so the paper feeds from the bottom up (or according to the specific diagram inside your device). Loading it upside down is the #1 cause of blank receipts.
3. Verify Paper Type: Ensure you are actually using thermal paper and not standard bond paper. Bond paper will not react to the printhead's heat.

What should I do if my POS machine stops printing?

If the printer is completely unresponsive—or if your POS screen explicitly flashes Error 8701 (a common system fault indicating a network timeout or communication failure)—it is almost certainly a network drop. When the POS software cannot locate the printer's IP address, it triggers this specific offline error. Here are the step-by-step troubleshooting actions to clear the 8701 code and restore your connection:

• Fix Dynamic IP Address Changes (LAN/Wi-Fi): If your store's router restarts, it might assign a new IP address to your network printer, breaking the connection. Print a self-test page to find the current IP address, update it in your POS software settings, and configure your router to assign a Static IP to the printer.
• Check Physical Cable Connections: Unplug and securely reconnect the USB, Ethernet, or Serial cables at both the printer end and the computer/terminal end. Ensure the ports are not loose.
• Resolve Cash Drawer Short Circuits: Sometimes a short circuit in the cash drawer kicker solenoid can freeze the printer's motherboard. Unplug the RJ11 cable connecting the drawer to the printer, restart the printer, and try printing again. Read our guide on common POS cash drawer problems and fixes for more details.

Is it a paper jam or a driver issue when POS won't print?

Differentiating between a mechanical failure and a software glitch is crucial. If your receipts look like a matrix of random letters or endless question marks, it's a driver/software issue. If the printer beeps, flashes red, or the cutter is stuck, it's mechanical.

1. Resolving Driver Issues (Printing Gibberish): A recent OS update can corrupt your printer drivers. Uninstall the current driver, restart the terminal, and reinstall the latest version. If using a Serial/COM connection, ensure the Baud Rate matches between the printer and Windows Device Manager. Download secure drivers from our Official Driver Download Page.
2. Clearing Paper Jams & Auto-Cutter Errors: If the auto-cutter jams, turn off the power immediately. Open the front cutter cover (usually by sliding it up) and manually turn the internal gear until the cutter blade retracts. Remove any crumpled paper.
3. Clean the Printhead: Dust and adhesive residue can trigger false sensors or faded prints. Turn off the printer, let the thermal head cool, and gently wipe it with a lint-free cloth moistened with isopropyl alcohol.

Frequently Asked Questions (FAQs)

Why is my POS printer not printing receipts?
This is typically caused by power disconnections, an open printer cover, network IP changes, or corrupted printer drivers. Running a quick self-test by holding the FEED button while powering on can help isolate whether the issue is hardware or software related.

What should I do if my POS machine stops printing?
First, check the physical connections (USB/LAN) and ensure the power light is steady. If using a network printer, print a configuration page to ensure the IP address hasn't changed. Restarting both the POS software and the printer is the fastest immediate fix.

How do I fix a POS printer that prints blank receipts?
Blank receipts are almost always due to the thermal paper being loaded upside down. Open the cover, flip the paper roll so it feeds from the bottom, and try again. Also, ensure you are using heat-sensitive thermal paper, not standard bond paper.

Is it a paper jam or a driver issue when POS won't print?
If your printer flashes a red error light, makes grinding noises, or the cutter is stuck halfway, it is a physical paper jam. If the printer feeds paper smoothly but prints random gibberish or strange characters, it is a driver corruption or baud rate mismatch issue.

Is It Time for a Reliable Hardware Upgrade?

If your printer requires constant resetting, frequently jams, or suffers from a failing motherboard, continuing to patch it up will cost you more in downtime and lost customer trust than a replacement.

For high-volume retail environments, reliable POS hardware is essential. We highly recommend upgrading to the TCANG 80mm Thermal Receipt Printer. Engineered with heavy-duty auto-cutters, ultra-fast 250mm/s print speeds, and seamless ESC/POS compatibility, it is built to keep your checkout line moving without interruption.
