I want to take pictours from my cellphone lg vx5500.and put them on my hp photosmart c4700

You can gain access to the service menu...refer to Cartridge Error Clear bypass procedure below (as guidance of how to get in):

For any severe cartridge error related message, on the HP C4600, C4700 or D110a printer models, I suggest you run the internal Tap 41 diagnostics test which will tell you the electrical health of the ink cartridge - in many cases the cartridge is internally electrically damaged and will need to be replaced. In addition, you can temporarily bypass an 'incompatible cartridge(s) or Missing/Not Detected error message by performing the Cartridge Error Bypass procedure...refer to two Youtube videos on how to do this:

as I know your LG cellphone can play 3gp and mp4 videos.so you need to convert the videos you have to the right format with right size.
You can have a look at this free MP4 video converter I have used for long.
that is easy one for using,

These types of severe cartridge errors (i.e. "refer to documentation" / "incompatible cartridges", etc.) typically indicate the internal micro-electronics of the HP #60-61 cartridge are electrically damaged. The cartridge's electrical wire runs at rear and lower side of the ink cartridge, are very delicate and are somewhat susceptible to ink attack over time, which can lead to premature failures. In addition, the older the cartridge the higher the chance of an internal electrical failure due to prolonged ink exposure and subsequent circuit corrosion. I suggest you always run a 'Tap 41' diagnostic test to check cartridges electrical health (this is a forced test); you may also bypass the error (temporarily) on C4600-C4700 models which use HP 60 cartridges.

Switch off the printer and switch on again,Unclip the cartridges one by one and clip back in again this sometimes cleans out the connector pins.This has happened to me.

Take off all the cartridges, power cycle the printer and re-install the cartridges

Thanks for using FixYa.

Some printers need special software (that shipped with the printer) to "tell" the printer that the ink-cartridge has been replaced, and that the ink-levels need to be fully "reset".

What is a incompatible print cartridge? The printer "Thinks" that the print cartridge, is NOT an original HP PhotoSmart one. Even print cartridge have chips.

Usually if you leave the printer off for sometime the ink get dry on the heads or some ink may leake to the sensores so take the cartrage out clean it and clean the heads with cotton swaps...see if the help and let me know
