Question about HP Officejet Pro L7780 All-In-One InkJet Printer

3 Answers

L7780 is not receiving FAXE'S. Only Some of it ??

Hi Expert,

I use the L7780 quite a while. So far It worked perfectly. A
few weeks ago I noticed that some faxes where not received
anymore. I customer did tell me, my fax is not receiving anymore. This is very strange and I can produce the following:

- Send a FAX from Faxmachine A works fine. The fax is
receiving.

- Send a FAX from my home Faxmachine, my L7780 in the
office refuces the reception.

This scenario is reproducable. I'am asking what has changed, since it work from both fax machines at the beginning ...

Any help would be appreciated.

Best Regards
Markus Meng

Just look for probably the remants of a paperjam (really little piece of paper) stuck in the sensor... have you removed and re-seated the toner cartridge? (sometimes HP machines will give that error if the catridge isn't quite seated right)

This is strange. Sounds like noise is in the line. Try searching the line for bad spots or replace the line. The ends could have corrosion on them also. The wires are most likely copper and the corrosion will be green. Check the box on the side of your house also. I would have the phone company check for noise in the line for you. Good luck.

Printers randomly stop working


Hi Will,

This machine doesn't have on and off switch. After changing label roll you need to unplug power for a few secs and plug it back in. This will stop windows from showing the "print error" message.

Missing characters, missing print barcode lines


Hi, It's been a while since I worked on these, so I'll go out on a limb (as far as my rating goes) and say that the few times I've seen that happen usually results from a bad network card. Now you may not be using a network card, so if your not then I'm not really sure what would cause that to happen on the printer side. The environments that I've seen that happen in are with an AS400 and the network card just gave out. You most likely tried this, but you might want to make sure that the computer isn't using one driver for both printers. Good luck.

Cyan cartridge


My IP4200 started doing this about a week ago it tells me I have two Cyan cartridges. I don't, cartridges are canon cartridges and were changed four months ago worked fine until now. Pressing the middle button the resume button is working eventually, so far, but I don't know for how long. Seems like a hardware problem as I deleted and reinstalled the software no difference and everything worked fine for the first four months.
