I can see the wave in some of my prints. PF Adjust, Page Feed Adjust

If you have a good media and a good profile the problem is usually PF adjustment.
You will probably need to perform the PF (page feed) calibration.

 OPTIMIZING YOUR VALUEJET PRINTS

1. Insure good nozzle check!  Nozzle check procedure is in the manual.

You can download a zipped version of the menus on our ftp site.
ftp://ftp.mutoh.com/Printer%20Information_Manuals/
Choose the folder with your printer model and find the "Manuals' folder.

2. Insure good uni and bi directional adjustment!  This procedure assumes that your machines has been properly calibrated in Maintenance Mode.

3.  Calibrate “Page Feed” You will need a fairly accurate millimeter measurement device for optimal PF adjust, a suitable steel rule is available from: McMaster-Carr, http://www.mcmaster.com/, the part number is 6823A62.

You basically need a pf adjust for each different type of media that you are using, you can save these in the user settings - there are 30 of them.

The first thing you need is an accurate mm ruler, 600mm will be the most accurate.

PF Adjust
Initial Print - pick 500 mm - this will print out sets of tick marks on each edge of the media.

Cut this piece off, lay it on a flat surface and measure - estimate between tick marks on your ruler. I.e. 498.2

Got back through the menu to PF
Initial Change - enter your measured value there.

Using this method I have rarely had to do the micro adjust.
If I use the micro adjust, I do so while the printer is printing, it is easier to see the difference while printing a

IF you use the micro adjust you can save in the current user setting - it is something like 'update' after the micro adjust menu. So that you wont have to do it every time.

The micro patterns are similar to your home printer, you should pick the 'best' pattern.
It is tougher to use if you are not very close already.

4. Media, a high quality media is preferred for best results. Typical heater settings are 40 Preheat, 42 Platen and 50 Dry.5. Profile - choose a profile suitable for your media.

Ideally, you will still want a profile created for your specific media.
