Epson Epson Stylus Color 600

Epson Color Stylus 600

I've been trying to recover the printhead of the above machine for the past several days.
Been the usual route with software cleaning cycles and printhead cleaning solution.

I'm down to one black nozzle not firing in "Normal" mode.
Printout is acceptable however, in "Best" mode.
Could this be a setting or a reprogramming of the EPROM ?

In my Service Manual a setup utility on floppy is mentioned.
I'm deducting that this would have come with the original hard-copy manual?
Am I on the right track ?
If you have a nozzle not working in any mode, then it is blocked.

OK, I've tried the cleaning solution regimen.
The nozzle check pattern is perfect.
Printing in "Best" mode is perfect.

The problem is in "Normal" mode.
I get a horizontal skip all the way across, the anomalys are about 3/8" apart. Maybe that equals one "pass" in Normal ?
It seems like a timing issue.
Is there a way to adjust that ?

Download the SSC Utility ( Google for it ).
Then RIGHR CLICK on the taskbar icon, configure it to your printer in "Show Main Window" --- in both windows, the main list and "installed printers" --- then RIGHT CLICK on the icon again and go into "head cleaning", "powerful cleaning".
This is a longer cleaning cycle than the normal one and so may well suck the offending nozzle clear.
Also try sringing a little clean water onto the capping pad to soften any thickened ink on it. This will also help to clean the pump tube so aiding suction.

Thanks David, for the response.
I use SSC and have already exposed the printer to its "powerful" cleaning cycles.

Since it prints a perfect nozzle check pattern and perfectly in Best mode, I am thinking that it's a timing issue in the Normal mode.

There has to be coordination between the printhead "passes" and the advancement of the paper.
I was wondering if there was a way to adjust this setting ?
