What This Error Means

TOSHIBA Error 20 typically indicates a problem with paper feeding from the cassette or a registration sensor malfunction, preventing the paper from reaching the fuser correctly.

Detailed Explanation

Error code 20 on a TOSHIBA printer generally points to an issue within the paper path, specifically concerning the initial paper pickup and registration. This error often occurs when the printer attempts to feed paper from a tray but either fails to pick it up, or the paper jams very early in the feed process, before it reaches the fuser unit. It can be triggered by misaligned paper, worn pickup rollers, or a faulty paper registration sensor that doesn't detect the paper's presence at the expected time. The underlying causes can range from simple user errors, such as an improperly loaded paper tray or incorrect paper size settings, to mechanical failures like worn-out feed rollers that can no longer grip the paper effectively. Dust or debris accumulating on sensors can also interfere with their ability to detect paper, leading the printer to believe there's a jam or no paper when there actually is. This error prevents any printing operations until the paper path is cleared and the feeding mechanism is functioning correctly.

DIY Troubleshooting Steps

Try these steps before calling a specialist

1
Turn off the printer completely and unplug it from the power outlet for at least 60 seconds to reset its internal systems.
2
Carefully open all accessible covers and trays, including the paper cassettes and bypass tray, to visually inspect for any jammed paper or obstructions.
3
Remove all paper from the affected tray (usually Tray 1 or the bypass tray). Fan the paper stack to separate sheets, then reload it neatly, ensuring it's not overfilled and the paper guides are snug against the edges.
4
Check the paper type and size settings on the printer's control panel. Make sure they precisely match the paper loaded in the tray.
5
Use a lint-free cloth lightly dampened with water or isopropyl alcohol to clean the paper pickup rollers in the tray. Rotate the rollers manually to clean the entire surface.
6
Inspect the paper registration sensor, usually located just after the pickup rollers. Gently wipe it with a clean, dry cloth to remove any dust or debris.
7
Ensure there are no foreign objects like paper clips, staples, or torn pieces of paper lodged anywhere in the paper path.
8
Close all covers and trays securely. Plug the printer back in and power it on. Attempt a test print to see if the error persists.
9
Try using paper from a different ream or a different tray if available, as sometimes paper quality or moisture content can contribute to feeding issues.
10
If the printer has multiple trays, try printing from a different tray to isolate if the issue is specific to one paper source.

When to Call a Specialist

You should call a specialist if, after performing all the DIY troubleshooting steps, the TOSHIBA Error 20 persists. This indicates a more complex mechanical or electronic failure, such as severely worn pickup rollers that require replacement, a faulty paper registration sensor, or an issue with the paper feed motor or clutch. These components typically require specialized tools and expertise to diagnose and replace correctly. Continuing to force the printer to operate with a persistent error can lead to further damage.
