All errors you can't solve, without replacing parts, will give an error call service centre. In only a few cases, it only has to do with a bad connection, but it also can be a problem with components becoming to hot and switching off. Please follow the advice the machine is giving. Too often people ask how they can put back together, some things they started "repairing" and could not work out how to. just saying.

Make the mirror image in the program on the PC first!

Hello, error 345 while faxing is related to Communication error. This error is not related to printer hardware issue. Below are the possibilities ....

1. The remote machine failed to respond to a fax command from the local machine because the connection was interrupted.
2. The remote machine failed to respond to a fax command from the local machine because the connection was interrupted.
3. The remote user pressed the Stop key while the reception was in progress. The suggested solution would be as follows....

• Retryt the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
• Disable ECM. Errors might still occur, and might result in a degraded image quality on the received page. However, the ability to send the entire document will be improved.
• Try sending at a lower transmission speed.

I've never HAD nor FIXED your model, but have fixed other HPs with different problems before. Re: your hp envy 4500 model printer: I researched a little, finding this: great product, January 12, 2014 Love the printer and it's performing great. I was thinking of giving this nice printer four 1/2 stars, because the direction should have emphasized more clearly that the paper holding tray must be pushed all the way back in to the printer not just the paper. So when you think the tray is all the way in give it another push. because one can not continue with any of the installations. It would not be fair to the product itself, to write negatively. Found the above here: Page 4: http://www.amazon.com/HP-Envy-4500-Wireless-Printer/product-reviews/B00CIDQ470?pageNumber=4 or read more here about the paper tray: http://h30434.www3.hp.com/t5/Printer-All-in-One-Install-Setup/HOW-TO-PULL-OUT-THE-PAPER-TRAY-ON-ENVY-e4500/td-p/3071717 It looks like the Paper Tray is persnickety on this model... Hope this leads you to a solution. {P.S. Recently when my almost 5 yr. old HP printer died-for good- I bought a "Brother" because I found they give you toll-free Tech Service "for the life of the printer"... and that's what I like!}

Hi David,Open the Front access door. You will find 2 Printheads. Check for an option on printer screen to Replace Printheads. Remove the Printheads, Clean the contacts with lint free cloth ( golden electrical contacts )Place the Printhead and close the Door.This should fix the issue.Regards,Sean

Hello, May i know the printer model # / name ( full ) to assist you better. ?

Hello James, Please click Vertical Bands Lines or Streaks in Copies Faxes or Scans to access the troubleshooting steps that should resolve the issue.

This is caused by an early driver version provided with the printer.

Download the latest version from the HP website, unplug your printer from your computer then uninstall your existing driver. Once that's successfully completely install the new driver version.

Unfortunately this doesn't always resolve the problem straight away so you may need to repeat this.

To check if you've resolved the problem:
- Go to START > Printers & Faxes
- Locate your L7780 printer
- right click and choose "printing preferences"
- choose the "Two-Sided (Duplex) printing" printing shortcut
- click on the "Advanced" tab
- look at the setting for "Mirror Image"... If you've succeeded this should now be set to "Off"... If it's "On" you still have a problem.


The problem itself is caused by some duff default settings which seem to stick whenever you've done anything that uses the "Two-Sided (Duplex) printing" Printing shortcut provided in the printing preferences.

In particular I've seen this crop up with PDF files...

The new driver does seem to resolve this but a further work around is to define a new duplex setting that has the correct "Advanced" settings and has "Mirror image" set to Off.


This solution also works for the K5400, L7580, L7680, etc...

Since you can send faxes, it's not the phone line or cord. It's most likely that you have the "distinctive ring" option set to something other than "all rings", check that first.
