Troubleshooting


Steps Actions
1 In most cases, a defective Photoconductor Unit (PCU) causes horizontal lines. This is especially true if the streaks are of only one color. Print some sample pages and verify whether the printout has improved.
2 Since the PCU is a Customer Replaceable Unit (CRU), the services of a technician are not required. Try replacing the PCU if you have an extra one in stock.
3 If you do not have an extra PCU in stock, or should the issue continue after you have replaced the PCU, please contact Lexmark Technical Support for additional information and assistance.


Note: If the source of the problem appears to be the PCU, it may be eligible for a warranty replacement; this is dependent, however, on the age and usage of the photoconductor.
