When the image quality trouble of print occurs, get a print to judge, understand and treat the trouble
substance precisely and appropriately, and then troubleshoot efficiently, using the image quality FIP
table according to each phenomenon.
When trouble restoration with image quality FIP is not possible, check again with the image quality FIP,
and then replace [ESS and possible causative parts] in order and check, and operate Troubleshooting,
using [Chapter 2 Diagnostic].
Image quality FIP states regarding the typical image quality trouble, as follows.
- FIP-1.P1 Faint print (Low contrast)
- FIP-1.P2 Blank print (No print)
- FIP-1.P3 Solid black
- FIP-1.P4 Vertical blank lines (White stripes in paper transport direction)
- FIP-1.P5 Horizontal band cross out
- FIP-1.P6 Vertical stripes

When horizontal lines and/or spot occur periodically, it is possibly caused by the
trouble of a particular roll. In this case, measure the trouble interval on the test
print, and check the relation to the roll in the table below. The interval does not
necessarily match circumference of the roll. The trouble may be solved easily by
the check.
