What This Error Means

The E.01 error code on OKI printers indicates a problem with paper feeding from Tray 1, often due to a jam or incorrect paper loading.

Detailed Explanation

The OKI E.01 error code specifically points to an issue with the paper pickup or feeding mechanism associated with Tray 1, which is typically the standard paper cassette. This error usually occurs when the printer attempts to pull a sheet of paper from Tray 1 but fails to detect its presence at the expected sensor point within a certain timeframe. This could be caused by a physical obstruction, such as a paper jam, or by the paper not being correctly loaded in the tray, preventing the pickup rollers from grabbing it. Beyond simple jams, the E.01 error can also signal worn-out paper pickup rollers that have lost their grip, preventing them from effectively pulling paper into the printer. Less commonly, it might indicate a faulty paper sensor that isn't registering the paper's movement, even if the paper is feeding correctly, or a mechanical issue with the tray's lifting mechanism. Understanding the exact cause often involves a systematic check of the paper path and the components involved in the initial paper feed from Tray 1.

DIY Troubleshooting Steps

Try these steps before calling a specialist

1
Turn off the printer and unplug it from the power source for 30 seconds, then plug it back in and power it on to reset any temporary glitches.
2
Open Tray 1 completely and carefully remove all paper. Fan the paper stack to separate sheets, then reload it squarely into the tray, ensuring it's not overfilled and the paper guides are snug against the edges.
3
Inspect the paper path around Tray 1 for any visible pieces of paper, dust, or foreign objects. Use a flashlight if necessary and gently remove any obstructions.
4
Clean the paper pickup rollers in Tray 1. Locate the rubber rollers (they are usually gray or black) and gently wipe them with a lint-free cloth lightly dampened with water or isopropyl alcohol. Allow them to dry completely.
5
Try using a different stack of paper or a different type of paper (e.g., plain copy paper) to rule out issues with the current paper supply.
6
If your printer has a manual feed slot or other trays, try printing from those to see if the issue is isolated to Tray 1.
7
Ensure the paper tray is fully and correctly inserted into the printer. Listen for a click or feel it seat firmly into place.

When to Call a Specialist

If you've followed all the DIY troubleshooting steps and the E.01 error persists, it's time to contact a qualified printer technician. This usually indicates a more significant hardware failure, such as severely worn or damaged paper pickup rollers that require replacement, a malfunctioning paper sensor, or an issue with the tray's lifting mechanism or a logic board component. These repairs typically require specialized tools and expertise that go beyond basic user maintenance.
