Digital BW, The Print

Interesting Steve, would you mind to post some pictures of this setting somewhere so we can fully understand ?
Even though I do not have a 1160 it can be very useful for any printer. And by the way, you can go back to see that technician and teach him how to do !

  I have been off line while traveling but I thought that this is worth
  sharing. I have 3 1160¹s and could never figure out why some printed better
  than others. I took one if for a tune up but still had the same fine banding
  problem- even with alignment and perfect nozzle check. I took the printer
  back and the repair person told me that I was nuts for demanding such
  precision. I didn¹t want to pay for the repair and we got into it a bit.
  After we calmed down he told me that what I wanted was very hard to achieve
  because the metal rod that carries the print heads  and controls the
  alignment only pivots from the right end and cannot be completely adjusted
  without major surgery.

  If you use the paper depth lever and then do a re-alignment you are tweaking
  the bar from the right end only. The left end is stationary so you are
  pitching the bar fore and aft. And this bar can sometimes be misaligned from
  the factory and you will never get a good alignment.

  The way to solve this problem is to take the cover off and you will see on
  the left end of the bar( opposite side from where the carts rest) a geared
  plastic housing that supports the bar. Undo the screws and move the bar one
  or two teeth in one direction ( make a registration mark with a sharpie
  before you move the gears ­ so you don¹t get lost as you will need to find
  the true alignment by trial and error.)  tighten the screws and run another
  head alignment and then print a test strip of an image that has given you
  banding in the past. If it is now worse you went the wrong way.....

  I did this to a printer that I was ready to toss and it now prints better
  than any printer I have. It is a bit of a pain but I was really amazed at
  how good a properly tuned 1160 can print.

  Best 

  Steve
