Test Print

The test print program is designed to ensure that the 168 printing mechanisms functions properly.
This printer will do a electrical test on all of it's printing mechanisms continously during printing.
However, this electrical test will not tell if something is wrong mechanically, and therefore it is
recommended to print a few pages of test print before beginning the day's production.
By doing so, it's quite easy to see if all printing mechanisms are functioning mecanically.
This printer has both single-sided and double-sided (interpoint) test print patterns.
See also TEST PRINT in chapter 3.2 "Operating panel functions".
The test print consists of four different patterns. A X-pattern, some full cell lines, empty cell lines,
the complete ASCII-table and a pattern consisting of a character with dot 1,3,5 combined with a
character with dot 2,4,6.
How to use the test print:
The test print button on the operating panel is used to start and to switch between the different test
patterns. To switch to the next test pattern, you must release the button, wait for the paper to stop
moving, and then press the button again. When you have reached test pattern number four, it will
start on number one again.
If you do not release the test print button, the printer will continue to run the test pattern without
stopping. This can be useful for troubleshooting.
If you do release the test print button, the printer will continue printing until the paper is positioned
correctly for the next print job.
- 1st test pattern:
Prints an "X"-pattern on both sides of the sheet which shows each pin from each magnet rack printing
on a separate line. Useful when searching for missing dots.
- 2nd test pattern:
Prints full cells and empty lines, together with the ASCII-table on both sides of the sheet. Useful for
testing the printing pressure adjustments, and to see how the paper can take heavy printing.
- 3rd test pattern:
Prints full cells and empty lines, together with the ASCII-table single-sided. Useful for testing the
printing pressure adjustments. To get the single-sided test print to alternate between the sides of the
sheet, LAYOUT 2 must be set to Z-fold.
- 4th test pattern:
Prints a test pattern made of dot 1,3,5 and 2,4,6, single-sided. Useful when searching for extra dots.
To get the single-sided test print to alternate between the sides of the sheet, LAYOUT 2 must be
set to Z-fold.
The chapter 4.1 "Printing principle" illustrates how the printing mechanisms are placed.
Instruction for troubleshooting will be illustrated by examples in chapter 4.2 "Troubleshooting".
