Want to know if there is a virus called 'Postcard"

Are you using Canon 4x6" PCP-CP400 Postcard Size Paper Cassette for SELPHY CP900/CP910 Dye Sub Printers??? Is the paper Matte or Glossy

Is the paper upside down?

Did you fan the paper at least 3 times?

It looks likes the unit comes with a Paper Cassette PCP-CP400 which is for Postcard Size paper. You should be able to reuse the Cassette for any postcard size paper. If you want to use L Size or Card Size paper you will likely need to purchase an additional cassette for that size.

Access "Windows Update" -- one of the updates is a virus-scanner (that Microsoft updates, once-per-month) to detect "common" computer-viruses.

Download the virus-scanner from http://www.prevx.com and run it.

Set the image size to 'postcard'. Press the Function key, scroll down to the bottom icon and select postcard (L, M1, M2, S, postcard). Press Function key again.

To turn the date imprint on, go to the Record menu and set the option for Date Stamp to Date or Date & Time.

The Yahoo Software comes with Spyware & Adware; never seen AT&T Yahoo Antivirus detect any virus in my experience. Unfortunately you have to install the software to setup your DSL for the first time; after that it's worthless. I would scan your computer with Microsoft Windows Defender or Ad-Aware by Lavasoft; both are free tools and find many of the common infections. Moreover, it wouldn't hurt to pay for a McAfee or a Nortin Subscription for virus protection; I use McAfee because it doesn't lag my system. There is a free virus protection program called AVG Free which I'm told works good for the price.

I had the same problem and took it into the dealer who firmly taped the battery door shut to get battery contact and told me that a new door would cost more than a new camera. It worked!

In order to embed the date in the photo, the camera has to be in the "Postcard" mode. That's on the same menu as the picture size -- L, M1, M2, M3, S, Postcard. Once set for Postcard mode, the date/time can be turned on.

Sometimes the BIOS calls this protection some sort of "virus protection" as past viruses, like the CIH virus would tend to overwrite motherboard BIOS' with jargon, bricking the motherboard. Try disabling any onboard "virus" protection and try flashing your BIOS again.
