Checking Carriage Movement
The random printing test exercises the carriage, carriage belt, and
carriage motor. During the test, the printer moves the carriage erratically
and prints a pattern of characters using various fonts, qualities, and
character cell sizes. The width of the test pattern is determined by the
WIDTH parameter setting on the Setup menu. By looking at the test
pattern, you can determine if the carriage is slipping due to a loose
carriage belt or pulley, or a malfunctioning carriage motor.
Before you run the test, make sure that paper is loaded in the printer.
Then, display the TEST parameter on the
Setup menu and select Random.
When you release the Alt button, the printer will begin printing the test
pattern. After printing several pages, press the Ready button to terminate
the test. The Setup menu will reappear.
If there is a problem with carriage movement, you will see characters in
the test pattern that overprint other characters. You may also notice that
the left margin shifted left or right as the test progressed. If you see
these problems in the test pattern, you should contact your Service
Representative for assistance.
