Printer Prints Only Left Side Vertically. Tonner Is Still Full.

Check the print settings: Make sure the print settings are configured correctly in the printer driver and the application you are printing from.

Clean the printer: Sometimes, dust or debris can cause printing issues. Clean the printer, especially the paper path and the toner cartridge area.

Check the toner cartridge: Even though the toner is full, the cartridge itself may be faulty. Try replacing the toner cartridge with a new one to see if it resolves the issue.

Update printer drivers: Ensure that you have the latest printer drivers installed. You can download the drivers from the Kyocera website.

If the issue persists after trying these steps, it may be necessary to contact Kyocera support for further assistance or to have a technician look at the printer.

1. Potential Causes:

Fuser Unit Failure: The fuser unit heats the toner to fuse it to the paper. A malfunctioning unit can cause partial or faint printing.

Dirty/Damaged Transfer Roller: This roller transfers the toner image to the paper. Debris or damage can hinder complete image transfer.

Faulty Drum Unit: The drum is the core of the imaging process. Scratches or uneven wear might create printing defects.

Incorrect Driver Settings: Less likely, but driver issues might cause partial printing.

2. Troubleshooting Steps

Clean the Transfer Roller:

Turn off the printer and unplug it.

Carefully open the printer to access the transfer roller. It's often a green cylinder.

Use a soft, lint-free cloth dampened with isopropyl alcohol to gently wipe the roller surface.

Allow it to dry completely before reassembling and restarting the printer.

Examine the Drum Unit:

If cleaning the transfer roller doesn't fix it, inspect the drum unit (usually found within the toner cartridge or a separate assembly).

Look for any visible scratches, gouges, or uneven wear on the drum surface. If damaged, the drum unit likely needs replacement.

Print a Test Page:

Print a printer-generated test page (usually accessed from the printer's menu). This helps isolate the issue from the computer/software.

Update/Reinstall Drivers:

Visit Kyocera's website and download the latest drivers for your FS 2000D.

Uninstall the old drivers and install the new ones. Check your printer settings after.

Fuser Unit Inspection:

This step requires more technical knowledge. If you're not comfortable, consult a technician.

The fuser unit gets HOT. Allow the printer to cool COMPLETELY before opening.

Inspect the fuser rollers for damage, debris, or uneven wear. Cleaning or replacement might be needed.

Additional Tips:

High-Quality Paper: Using the correct paper type for your printer can prevent print quality issues.

Shake Toner: Gently shake the toner cartridge to redistribute toner if it's been sitting for a while.

If none of these steps help, you might need professional repair services to diagnose and replace the faulty component.
