Hi Guys,
I'm having a problem with a HP T2300 Plotter, Image quality is out of calibration on the Cyan/Magenta Head only.

As usual it looks like a normal print head issue as it was out of date and so was the ink.
It basically looks as if it is printing several lines over to the right by a few mm.
This is what we have done so far. Luckily we have a perfectly working T1100 here in the shop to use some parts that are the same and to do some other testing.
1. New Ink & Head, Still same issue.
2. Cleaned Drop sensor, line sensor, optical sensor.
3. Tried known working head from the T1100 and the new head in the T1100, All fine in the 1100 but same issue in the 2300.
4. Tried known working Encoder strip/drop sensor/optical sensor from T1100. (All Same parts).
5. Tried all Calibrations and test in service mode. All results ok.
6. re seated all connectors relating to the carriage and heads.
When printing a larger page it looks as if one head width if perfect then the next head width had all lines across it, This repeats all down the page consistently.
Normally i would think the p/head alignment should have failed, but it doesn't it just says all ok.
If there is any thing you guys can think of it would be greatly appreciated.
