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

Occasionally bottom line of document only partially prints

Occasionally only the top half of the bottom line of a document prints, on maybe one out of six documents sent to print. I am running Vista Ultimate 64 bit and sending to the printer over a wireless private network from a HP Pavilion laptop. I haven't noticed if this problem is only on documents sent to the printer from the laptop or if it is happening on faxes and scans. I am not low on ink.

    My LAN consists of 2 new compact laptops connected via ethernet cable to Netgear router and then to the HP L7780 AIO printer. I am using windows Vista home edition. I have used the HP l7780 v 8.0.1 print drivers. In Word (office 2007 edition) the bottom half of of the last line is cut in half. Also the footer disappears when this happens. This also happens with an electronicl record program I use called Soapware which is not a MS product. It does not happen everytime; print a single page word document results in 3 bad pages out of 5, 1 bad page out of 4, etc.

    I have spents 10+ hours on the phone to HP and more hours than I can count trying to fix this. HP has had me do multiple install/uninstall of the HP software. We have done a complete fresh install. Nothing seems to fix the problem . They blame it on everything except their printer; its MS office, its Windows Vista, its the network, etc.

    Couple of things I have discovered; if you check the print preview in MS Word you will see the entire document is there. HP has had me use other print drivers (office jet d series and hp deskjet 990c drivers) and this seems to have eliminated the problem. Unfortunately this also seems to have created problems with faxing from the computer. This could be a great AIO but the problems in getting it to work consistently defy description. It is more trouble than it is worth at this point in time.

    I have the same problem witht the bottom lines of word documents being cut off periodically. I am running windows vista and office 2007 on a compac (hp) F700 notebook. I also have the same problem when printig reports from a program called soapware. I have spent way too much time on the phone with HP customer assistance. They say this is a unique problem to me. So far their fix has been to install the 990c print drivers to print and the 7700 series drivers for faxing. Problem with the 990c drivers is they cause the printer to use colored inks to produc black print which means instead of being an economical printer (1.5 cents a page they claim) this is now one of the most expensive printers per page. For the second time I have been told my problem is being elevated to engineering for a fix.

    Printing out of Corel X3 -and- Word 2007. Cuts off bottom 1/4 of documents. Using Vista on an HP machine. Doesn't always do, it but today it is persistant.

    Sometimes I have the same problem. So HP's statement that you are the only one is not correct. I have tried everything, rebooting the computer, rebooting the printer, copying the text to another document, so far no luck.

HP has newer drivers out for the Officejet L7780. If your printer is still under waranty call them and have them uninstall your current drivers via remote access and install the newer drivers. If it is not under waranty then do an install and then install the new drivers yourself. I finally took my Officejet L7780 out of service except for faxing and minor print jobs. The fax still messes up the cutting off of the last row of text seems to be fixed.

This is not really a fix it simply covers the symptom; Print a line of numbers or letters at the bottom of the page, the use less line gets cut in half not your important stuff.

The HP L7780 is a piece of junk. You only have to search google to learn many folks are having the same problem. After multiple install/uninstall of drivers over the past 2 years (HP replaced the unit twice with remanufactured L7780) they finally admited the L7780 is not reliable and replaced it with a HP 8500. It took more time and effort than it was worth but I hate getting ripped off by being sold expensive junk. The HP8500 works most of the time and is a huge improvement over the L7780. The real fix was to buy a Canon. I started with a Canon Pixma MP830 which has never had a problem (other than cost of ink) and then a Canon Image Class 4350d laser which is also proving to be bullet proof. .

Why does every other line of print have the top half of the print cut off?

The print head prints two lines of text/image at one time. If there is a partial print of alternating lines, you probably have a partially clogged print head. Print a test page to see what you get, and perform head cleaning process if needed.

Last print line of any doc printed with HP J6480 is cut off

I had been experiencing this problem intermittently for some time, so I finally got a hold of HP support and with the second support technician, I did get a solution that worked for the document I was printing at the time. When Printing, click Printing Preferences, click the Advanced tab, under the Printer Features section, set Minimize margins to On. Per the technician, 'The printable area of the product increases (bottom margin 12 mm to 3 mm), so that printing closer to the edge of the paper.'

Also, he recommended using the printer's Print Preview option under same the Printer Preferences window. When I did, I did in fact see the document's bottom paper being 'cutoff' with the old settings (i.e., Minimize margins Off), with it On, it look okay.

Hope this helps. Let me know if this works for you.

Printer will occasionally print incomplete document

Sounds like an issue with the bottom margin and/or footer if you are using a footer. Check the page setup and reduce the bottom margin.

Prints complete lines with occasional lines half height of letter

Your printer cogs may be damaged or your paper rollers could be slipping resulting in this "odd" output.

Paper rollers can be cleaned with an appropriate cleaning kit but if the cogs are damaged it's not worth repairing.

#5 black ink cartridge skips through the middle occasionally

Replacing the print head
The print head may need replacing if, after all print head and ink tank troubleshooting has been performed:

  • The nozzle test appears broken or to have horizontal white streaks.
  • One or more of the colors is missing from the Nozzle Test.
  • The colors are incorrect on the Nozzle Test.
  • A print head error is indicated on the unit.
  • The printer powers off when the print head is installed.
I hope it helps!!!
