Phaser 840 Printhead Question (please help)

[phaseol]

I believe the 840 I recieved as junked may have a bad printhead. I just fixed the y-axis assembly it now can move on to this. I am afraid I don't know if the printhead is the problem. My question is: is the printhead the part that the wax actually buts up to and is melted by? It appears to me that the ink is not being melted. Also, I thought the actual touching piont would be extremely hot, yet I can fiscally touch it with my finger and barely feels warm. Am I on the right track. I have traced down a printhead for $475.00 is that reasonable if it is the part I need to replace?

The part you are referring to is the ink load assy. It melts the ink into the printhead. If the head is full of ink then the heaters will not fully heat up to melt ink which is why it may just feel warm. What problems are you experiencing to make you think the head is the problem?

I do not know what problems I will have after I deal with this one. I am a novice to this. Are you suggesting that I can clean out the excess ink from the "ink load assy" and that might help fix it?

The pages that print out are very light, as though they did not get enough ink, and faded.

I would check first to see if the printhead has ink in the reservoirs. You need to remove the ink load assy and physically look into the holes on top of the printhead to see if they are full of ink. If not and the ink loader is not melting ink to replace it then posibly there is a problem with the sensors in the head, which means it needs to be replaced.
