After getting some banding on a print, and then printing a diagnostic image, I saw some banding on the green patch. It only got worse after doing a head cleaning so I replaced the Blue/Green printhead (it was out of warranty). After that I got a message that the printhead replacement was incomplete and I needed to restart the procedure. That didn't work. I cleaned the contacts and printheads and continued to get the Restart Printhead Replacement message so I entered the Service Tests (Diagnostics) menu from the front panel and ran the Carriage Assembly test. Several results didn't jibe with what the service manual said. The manual said that the Carriage Voltage (+Vs) should be between 43.6 - 46.3. My results from the test showed the voltage to be 32.135. In another test, the manual states that The Carriage Assembly PCA Rev. "must" be between 0.23 - 1.005, my results are 2.313. The test failed with an error 58.11 DeltaE out of limits 92.000 > 8. The ESP color sensor checked out ok in the Carriage Assembly Test, as did all of the sensors when I ran the Sensors test. The Electronic Modules Test passed, and so did the Ink Delivery Test. That leads me to think that the Carriage Assembly PCA board is bad or the Carriage Assembly itself is bad. The service manual states "

  • If the problem persists check the internal code error (Press UP and CANCEL while the error is displayed). If the internal error code is 0x0606002 replace the Service Station. If the internal error code is 0x06060003 change the Carriage PCA"

I can't check the internal code error because I never got an error while printing, which seems to be necessary to check the internal code error, and I can't press the appropriate buttons from the service menu because that cancels the test and shuts off the printer.

 

The problems seems to be one of the Color Sensor ESP, the Carriage PCA, or the Service Station. Can anyone here help me narrow it down or help me solve the problem?

Thank you!
