Correct The Ink Drop Position For Bidirectional Printing - Ricoh L4160 Operation Manual

Correct the ink drop position for bidirectional printing

When the condition for printing (media thickness/head height/etc.) has been changed, perform the following
operation to correct the ink drop position for bidirectional (Bi) printing and obtain the proper printing result.
Example of a Drop Position correct Printed Pattern
• The correction pattern for aligning the ink drop position cannot be printed on a media whose width is
less than 450 mm. Print quality cannot be guaranteed in such a case. Use unidirectional printing.

• Corrected feeding rate: -40.0 to 40.0
• Open the front cover and check the test patterns. The position where an outward feeding line and a
return feeding line become one straight line is the correction value.
