Hello! I have a HP Deskjet D1560 printer, and i have a problem with it. The power light blinks constantly, and the ink cartiges don't move when i open the case. Also, when i connect it to the PC it says "USB device not recognised". Please help me!

First of all understand what is cartridge the you can solve your problem your self in future if related same: The cartridge contains two parts 1. ink tank, 2. Pen(electronic nozzles controlled by mother board).. Ink tank contains ink & main source to pen to write,.. if ink is over you wont get any image.Ink is there but pen is not writing then no use..both conbination has work to gether to create image..As you said ink is there, but pen is not working due to ecetronic nozzles are faulty & this information with mother board, that's why its indicating that replace the cartrdige..And we can't repair it because of micro technology.
See fig: 1. Container, 2.Nozzles. 3. Electronic contacts to control nozzles..



Just replace the cartridge....

It is ink cartridge problem. Change it with genune one. problem will be solved.

Your printer must be out of ink,which is why its not printing.

Hello
I believe the ink cartridge should have ink but not sufficient for printing, if the cartridge is expensive why dont you re-fill it, re-filling is very low cost option.
Also clean the contacts of cartridge from both ends.
Hope this helps, if so do rate the solution Good Luck

your one cartriage is short replace and then check

HI there.
The first thing you can is to open the cover and remove the ink head.Then clean their contacts and the ink head carrier of any ink on them.Then turn on/off and try again.

After your printer has completed its initial startup you should have a solid green light. If the light indicator is blinking or orange often this is an indication of a printer error. For example, this could indicate a paper jam, issue with the ink or toner cartridge, or other serious error.
Because there is no standard to what a blinking light or orange light means if you're getting either of these we suggest referring to the printer documentation for troubleshooting steps or methods of determining what the status indicator is reporting.
