3.6 Test print
The test print program is designed to ensure that the 180 printing mechanisms functions properly.
This Printer will do an electronic test on all of it’s printing mechanisms continuously during printing.
However, this electrical test will not tell if something is wrong mechanically, and therefore it is recom-
mended 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 mechanically.
This Printer has both single-sided and double-sided (inter point) test print patterns.
The test print consists of four different patterns. See the description below:
How to use the test print:
Print Test Pattern:
Main Menu - Warning - Service/Diagnostic - Warning - Print Test Pattern
When entering this menu choice, a warning window will appear.
This is to make the user aware that print jobs from the computer will
not be printed as long as you are in this sub-menu.
- X pattern
Will print dots in a x pattern across the sheet,
useful when searching for missing dots.
- Full cell, single sided
Prints all six dots on all characters on one side of the sheet,
useful for dot quality tests.
- Full cell, both sides
Prints all six dots on all characters on both sides of the sheet,
useful for testing how the paper quality can take heavy printing.
- O/Ø pattern
Prints a test pattern made of dot 1,3,5 and 2,4,6, single-sided, useful when searching for extra dots.
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, incor-
rect Braille”.
