Phaser 350 printing problems / test print questions

[oscarthegrouch]

Hello,

one more question on the Tektronix (Phaser 350): the very first test print after turning on the printer _always_ has a wide vertical white bar, seems that there is nothing printed. After doing a small cleaning cycle the printer prints a nice test print, except for some spots.

Unfortunately the Xerox site gives no answer to this problem :-(

Does this behaviour indicate a defect cap/whipe/purge unit, for example a broken gasket?
Or might there be an error in creating a vaccum?

When the printer is turned off it takes about a quarter of an hour until it can actually be turned off. I assume that
the printhead, i.e. the nozzles, will be heated up and then purged completely. Does the cap/whipe/purge unit then cover the printhead or is it "left open"?

Are these assumptions correct?

Furthermore the test prints have random black spots in the upper right area of the test print. Such spots occur when printing from a computer but are not as large.

Does this indicate a defect cap/whipe/purge unit?

Would be nice to hear from the experts,

oscar

First for the spots at random i would try to do an cleaning for inksmears.
Second, your assumptions are correct.
This can indicate a problem whit the cwp and or the vacuum thad is to low. The cwp covers the printhead while cleaning/purging whit vacuum. Try and changing the CWP and go from there.

The extensive cool down period is to ensure that the Molten Ink solidifies before being moved - consider the damage that molten ink at 120 to 150 degreesC will cause to PCB's as well as blocking sensor windows etc.
