Kodak 8810 print head change with used print head

[Kws2868]

Hi,

I was cruious if anyone has changed a print head from a 8810 with a spare used Print head from another 8810 printer? I changed one printhead out of from one 8810 to another and then I changed it to match the right voltage, but now it's coming up with a TPH Setting Err issue? What is this issue and how can I resolve it?

Thanks,

Ken

I figured it out  if your changing print heads out for a used one, make sure to grab all the density settings off the previous unit that your grabbing the used part from. Then change the density settings on your new unit with the used print head installed. The 6850 and 6800 don't seem to have this issue, as long as you get the voltage right, your all set to go.

The print density is set to the value on the specification packed with the new
THERMAL HEAD AY

[1] Do:
• DC POWER SUPPLY: Voltage for the THERMAL HEAD AY 
• Print Density on 
• Print Position on 
[2] Test for the correct operation of the equipment.
