Initial issue
IQ5 Residual Image (Ghosting) RAP
Initial Actions
• Check the end-of-life counter for the Drum Cartridge. If the unit is at or near end-of-life,
replace the Drum Cartridge (see Machine Consumables in Section 6).
NOTE: Some ghosting on transparencies is unavoidable.
• If the problem occurs only with certain types of media, ensure that the media in use is
within specification, and that the customer is aware of correct operation of print driver.
• If the distance between the intended image and the residual image has a fixed rate of rep-
etition, go to the IQ14 RAP. Return to this procedure if the problem persists.
Procedure
The problem is with a single primary color
