Question Latex 560: How do I know when it is time to replace a printhead?

[karst41]

Over 200 nozzled dropped out is not too good.
Run this pattern. NO Color Correction.

If banding is not cleared by the 3rd printing manually clean the head with a foam qTio and 50/50 IPA water.
or just buy a new print head. $140 and get back to work

It's just usually a complete waste of time to print this or anything because it's not using the blocked nozzles....
Cleaning from the menu is the right way. Then manual cleaning.

What ever.

Run 3 coppies of this print Color Correction Off
If print head is not suitable then pull the head for a manual clean.
Will the print head dry out before you can run another cleaning cycle? No Probably Not.

If shop is busy run my print.
Is still showing streaks just replace the head and calibrate. Otherwise you are just wastin
the Maint Cart.

BTW you run this with no color correction because that weak pissyellow from HP
is firling Lm to compensate.

Watch this print as it is ripping.
You will start seen the streaks go away by the time the Lc Lm heads start firing.

Be sure that this print is in CMYK Mode. This forum will not let me upload the eps. Sorry
