Hi, this is Michelle and i will be assisting you
please try the below steps first
please take out the print cartridgewait for the insert cartridge message to appearunplug the power cord...Clean the golden contacts of the cartridge with a cotton swab dipped in little alcoholwait for 2-3 minutesplug the power cord back inturn the unit on and reinsert the cartridges check for functionality
let me know the status once done
I have tried what was suggested I.E taken out all the six Ink cartridges and cleaned all the contacts but the message still appears -that the ink supply is not working and repeating the error message Oxc05d2281
does it say something like ink system failure on the display
please let me know if in addition to the error code you get any error messages as well
Yes the error message does say that there is an 'ink system failure
well in that case it seems to be an issue withe the printhead
usually this requires a replacement of the printhead
however you may try one step
turn off unit...remove cartridges...remove the printhead..clean printhead contact point with cotton and alcohol
reinsert and check
if you still recieve the error then its a printhead failure and would require replacement
if unit is within warranty cover then get it serviced through HP else need to take it to a local repair shop
let me know if you have any queries
Reset the system by holding down the OK, Cancel, Black, and Color buttons down at the same time and turn the printer off.
Keep holding the buttons down until the printer shuts off and the turn it back on.
You will have to turn the printer off twice and then it will recalibrate.
