Question about Cisco Photosmart C4780 Wireless AllInOne Printer With Linksys By Cisco WirelessN Broadband Router

I have an HP Photosmart C4780 printer. When using Photoshop on a Mac laptop, it is printing a dashed vertical line at the right edge of many (but not all) pages. Have tried rescaling, changing ink cartridge, changing paper, changing margins..

Hello,

Thanks for using FixYa.

Sounds like you have a clogged printer head. Unlike the old HP printer models that has the printer head attached to the ink cartridge, the C4780 has the printer head built within the printer itself so reduce the cost of print cartridges. This sacrifices the life span of the printer though, because once the print head gets clogged or damaged, you will be sending the printer to HP for repairs. They will replace the print head. Replacing the print head will cost almost half the price of the printer itself so if your printer is already out of warranty, I suggest that you just get yourself a new printer.

What you can do to de-clog the printer head is to do a head cleaning. Goto the printer maintenance screen then select "clean printer head"

Here are some tips to avoid print head damages or clogging:

1. Don't print more than 20 pages in one sitting. This will cause the printer head to overheat and get damaged. After printing around 20 pages. Let your printer rest for 2-3 minutes.

2. Use your printer at least once a week. This will prevent the printer head from clogging.

I hope this helps. Thanks and have a nice day.

Can't scan pictures from my HP F4280 to my Mac.


Seems like you have installed only printer driver. Download the scanner driver for device seperately and install the scanner software also. And try again.

HP Photosmart C4780 and Acer Aspire fight over web-based printing!


Try hard-wiring your laptop to the router with an ethernet cable as a test and then try printing, if you do not loose connection to the internet then the problem is probably that the printing is hogging your wireless bandwidth.
If the same thing happens with loosing connection to the internet try connecting to the internet real quick through another computer that is hardwired, you want to find out if the problem is a wireless one or that affects wired computers also. You might need a driver upgrade, you also might need to upgrade the firmware of the router

How do i get a mac address for a hp c4780 printer


Hi. Open Setup on the printer control panel (this should be under the Scan icon) and there should be a Network (config or test, I don't quite recall) section available. The MAC address will be in there. Cheers.

This evening I bought a new HP Photosmart C4780 printer. I am trying to print photos now and the photos are being printed with small vertical lines across the whole photo. How do I get rid of them?


> I bought a new printer

Take it back, and get one that does work correctly.

> VERTICAL lines ACROSS the whole photo

Hold the paper in "portrait" mode, not "landscape" mode.
Are the lines HORIZONTALLY-ACROSS the paper,
or VERTICALLY-DOWN the paper?

If those lines are WHITE and HORIZONTAL,
then some of the many ink-jets inside the print-head are *CLOGGED*.
Run a "print-head-cleaning-cycle" to try to unclog it.
Or, exercise the WARRANTY, and get it replaced.

Cannot connect my laptop to wireless


Your wireless printer might frequently lose its communication with the computer and hence might not print all the documents when you want. Such an issue arises when there is interference in the wireless signals between the printer and the computer. This could be caused by any other wireless device kept in the vicinity of your printer like a cordless phone. Keep all other wireless devices way from the printer set-up to tackle this issue. Also bear in mind that if your system is turned on for hibernation mode then it would disconnect your printer the moment it goes into hibernation. get more help http://h30434.www3.hp.com/t5/Printer-All-in-One-Install-and/HP-Photosmart-C4780-Wireless-Printing/m-p/320321#M19172

HP C4780 photosmart won't make copies. It will


this is the Correct link to download the Software by choosing the Operating system but if you say if you are not able to make copies, is it from the printer itself..

I get a line through my scan with my hp photosmart C6180, What can I do?


If it is a vertical line, you could review the HP support documentation for your Photosmart C6180 here:

HP Vertical Lines Bands Streaks

For horizontal lines, try using the HP "toolbox" to clean the print heads. You may need to repeat this process until you achieve a satisfactory result.

Printing from Elements 6 w/ HP 8250, image pushed to left.


I wish I did have a solution. Photoshop Elements 7 exhibits the same problem. They obviously broke something. I have to use an old version of Photoshop Elements 4 just to print properly. I am a tech support professional, uninstalled all HP software, re-installed latest drivers and problem persists. Sucks.
