Hi @WalterParkerson,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
It sounds like the issue with your HP LaserJet 4000 could be related to the printer's hardware, particularly the transfer roller, fuser, or a problem with alignment or calibration after the move. Here are a few steps you can try to troubleshoot and potentially fix the issue.
Check the Printer's Transfer Roller:
- Open the printer and locate the transfer roller. It’s a long, cylindrical roller usually found under the toner cartridge.
- Check if it’s dirty or has any debris on it. Gently clean it with a lint-free cloth.
Inspect the Fuser:
- The fuser is responsible for bonding the toner to the paper.
- If the fuser is not heating evenly, it can cause print quality issues.
- Make sure the fuser is properly seated and not damaged.
Perform a Printer Calibration:
- Sometimes, moving the printer can cause it to go out of alignment.
- Look for the calibration options in the printer's menu and perform a calibration.
Check the Paper Path:
- Ensure there are no obstructions or debris in the paper path that might be affecting print quality.
- Check the condition of the rollers and guides.
Run a Printer Cleaning Cycle:
- Most printers have a cleaning function that can help clear any built-up toner or debris that might be affecting print quality.
Check for Firmware Updates:
- Ensure your printer's firmware is up to date. Sometimes updates can resolve printing issues.
Reset the Printer:
- Turn off the printer, unplug it, and wait a few minutes before plugging it back in and turning it on again.
Print a Configuration Page:
- This will help you determine if the issue is with the printer hardware or the print job.
- If the configuration page prints correctly, the issue might be with the print job or the connection between your computer and the printer.
I hope this helps.
Take care and have a good day.
