Hi @SIMIC2,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

Thank you for reaching out. I tried checking for the model “HP LaserJet M139242e”, but unfortunately, this exact model number doesn’t match any HP LaserJet product in our database. It’s possible that:

• The model name printed on the printer might look similar, but is slightly different

Common LaserJet models in this family include:
HP LaserJet M139-M142 series, M140e, M141e, M209, M234, etc.

To help you correctly, could you please check the model name on the front of the printer or on the sticker underneath/behind the printer?

About the error code “ER01”

Since we don’t have the exact model confirmed, here are generic HP LaserJet ER01 troubleshooting steps:
 

ER01 on most HP LaserJet printers usually means:
Paper Feed Error / Paper Jam / Paper didn’t pick correctly
 

Try these steps:

1. Remove all paper from the tray
   Fan the stack, make sure the edges aren’t stuck, and reload it.
    
2. Check for any paper jams
   Open:
   • Input tray
   • Output bin
   • Toner area
   • Rear access (if your printer has one)
      
3. Remove the toner cartridge
   Look for any tiny scraps of paper around the rollers.
    
4. Clean the pickup rollers
   Use a slightly damp, lint-free cloth to wipe the gray rubber rollers.
    
5. Restart the printer
   Completely power it off, unplug it for 30 seconds, then turn it back on.
    
6. Try printing a test page

I hope this helps.

Take care and have an amazing day!
