From the FUNCTION menu, select PRINT TEST PATTERN.
In this test, the printer unit will be used to print various patterns. For service work, be sure to use the BLACK pattern and the SQUARE pattern.
Use the BLACK print pattern to meke sure that the printout is free of white lines and unevenness; on the other hand, use the SQUARE printout to make sure that
the printout is free of image contraction, elongation, and soiling.
MEMO
After completion of the print test, if the printing was normal, copy a document. If there is any defect in the copied image, there is a defect in the scan
section.
