Chapter 2: Setting Up and Using the Printer

Testing the Printer

Test the receipt station using the simple tests described in this section. To further test the
receipt station or to test the slip station, run the level 1 diagnostic tests described in "Level
1 Diagnostics" in "Chapter 4: Diagnostics." See "Chapter 3: Solving Problems" for what to
do if the printer is not functioning properly.
The tests print data about the printer's configuration which is useful to a service
representative if there is a problem. The settings for the various functions which control the
configuration are in "Level 1 Diagnostics" in "Chapter 4: Diagnostics."
The tests also print all variations of the character sets with a partial cut between each
variation. See the sample on the facing page. The tests end with a partial cut, then begin
again. Several feet of paper can be used to print one pass of the test.
