IQ24 Ghosting

This RAP addresses image quality problems associated with the Print Engine. Ghosting typi-
cally results from stacked prints, faulty or expended Drum Maintenance Kit, or Drum thermal
regulation. Ghosting is indicated by images from a previous print appearing on subsequent
prints as follows:
Figure 1 Example of Ghosting on Output
Initial Actions
1. Check that supported media is being used.
2. Check the Drum Maintenance Kit.
Procedure
Step Questions and Actions
1 This problem can occur when prints are
stacked in the Output Tray. The resulting
pressure, and system heat causes "blocking"
which has the appearance of ghosting.
Print the Weak/Missing Jet test print.
If there are discolored jets, print the Solid Fill
test print for the affected color.
Does the problem persist?
2 Run multiple, 2-sided prints. Some amount of
Transfix Roller ghosting is inherent to the sys-
tem. This type of ghosting is most pro-
nounced on the first 2-sided print. Ghosting
should fade on subsequent prints.
Does the problem persist?
