Phaser 360 Sawtooth Print Pattern?

[l21]

I recently picked up a Tektronix Phaser 360 and as it urns out the previous
owner had spilled magenta ink inside, probably tried moving it before waiting
till it cooled down, and he also put black ink inside the the yellow ink chamber.<br>
<br>
I cleaned it up and flushed out all the black ink by doing about 10-15 cleaning
cycles but now my problem is I get these verticle banding lines with a sawtooth
|||| pattern on the text and graphics...I do have pdf samples if anyone can help.<br>
<br>
What's strange is the both the Cleaning & CMYK Test Pages are fine showing crisp
text and no sawtooth/banding lines BUT the Start Page is all messed up.<br>
<br>
I would really appreciate if some Service Tech. could advise me as to what
might be causing this print problem...I'm stuck up here in Canada because
nobody touches these older units anymore.<br>
<br>
Again, any help in the matter would be greatly appreciated!<br>
<br>
Cheers,<br>
