What This Error Means

Lexmark Error Code 20 typically indicates a paper jam or media feeding issue originating from the input paper tray.

Detailed Explanation

Lexmark Error Code 20 is a common message signaling that the printer has detected a problem with paper feeding from one of its input trays. This usually means that a sheet of paper has either failed to pick up correctly, has become crumpled or torn during the pickup process, or has stalled before it can even enter the main paper path. Sensors within the paper tray assembly and initial paper path detect this anomaly, triggering the error code and halting print operations to prevent further damage or wasted supplies. The root causes for this error can vary, ranging from simple user-related issues to more complex mechanical failures. Often, it's due to improperly loaded paper, using media that is too thick or thin for the printer's specifications, or paper that is curled, damp, or dusty. Over time, the paper pickup rollers, which are responsible for grabbing paper from the tray, can wear out, become dirty, or lose their grip, leading to misfeeds. Less commonly, foreign objects falling into the paper tray or a malfunctioning paper sensor can also trigger this specific error code. Addressing this error promptly is crucial not only to resume printing but also to prevent potential damage to internal components if paper is forced through a jam. While often resolvable with basic troubleshooting, persistent occurrences might point to components needing replacement or professional intervention.

DIY Troubleshooting Steps

Try these steps before calling a specialist

1
Turn off the printer completely and unplug it from the power source to ensure safety before proceeding.
2
Carefully remove the paper tray(s) from the printer. Inspect the tray for any foreign objects, debris, or crumpled paper.
3
Remove all paper from the tray. Fan the stack of paper to separate sheets and then reload it neatly, ensuring it's not overfilled and the paper guides are snug against the paper stack without being too tight.
4
Inspect the paper pickup rollers visible at the front of the paper tray cavity. If they appear dirty, gently wipe them with a lint-free cloth lightly dampened with distilled water or isopropyl alcohol. Allow them to dry completely.
5
Look inside the printer's paper path entry point (where paper goes after leaving the tray) for any small pieces of torn paper or obstructions. Use a flashlight if necessary.
6
Reconnect the power cord and turn the printer back on. Allow it to complete its startup sequence.
7
Attempt to print a test page. If the error persists, try using a different stack of fresh, unused paper from a sealed ream.
8
If your printer has multiple trays, try printing from a different tray to see if the issue is isolated to one specific tray.
9
Perform a factory reset if the error continues, as sometimes a software glitch can cause persistent issues (consult your printer's manual for specific reset instructions, as this will clear custom settings).
10
Update your printer's firmware to the latest version, as manufacturers often release updates to fix known bugs and improve paper handling.

When to Call a Specialist

You should consider calling a specialist if, after performing all the DIY steps, the Lexmark Error Code 20 persists. This is particularly true if you notice visible damage to the paper pickup rollers, hear unusual grinding noises when the printer attempts to pick up paper, or if the error occurs consistently with different types of paper and trays. A professional technician can diagnose internal sensor failures, replace worn-out pickup rollers, or address more complex mechanical issues that are not user-serviceable.
