Hi @Cathy321 

Welcome to the HP Support Community!

Thanks for posting your query! We're here to help you get back up and running.

That black line on the left side of your prints is a common issue with the HP Color LaserJet Pro MFP M283cdw. Here are some HP-based troubleshooting steps to fix it:

Step 1: Clean the Scanner Glass & ADF Strip

• If the issue appears only when scanning or copying, the ADF glass (the small strip next to the main scanner glass) might be dirty.
• Use a lint-free cloth with glass cleaner to wipe both the flatbed glass and the ADF strip.
• More details on cleaning can be found here.

Step 2: Run a Cleaning Cycle

• On the printer’s control panel, go to Setup > Device Maintenance > Cleaning Page.
• This helps remove toner buildup inside the printer.

Step 3: Check the Toner CartridgeRemove the black toner cartridge and inspect it for leaks or damage.

• If you see excess toner inside the printer, gently clean it with a dry, lint-free cloth.

Step 4: Inspect the Fuser & Transfer Belt

• If the black line appears on all prints, the fuser unit or transfer belt might need cleaning or replacement.

Step 5: Update Firmware

• Go to HP’s support site and check for the latest firmware update.
• Some users have reported that a firmware update resolved print quality issues.
