Try to print for 10~15 of blank pages to dislodge the foreign material under the wiper blade. Consequently, take out the cartridge and open the shutter and see if the OPC surface is already being damaged by the foreign material (check if the dirt lodge had appeared on OPC and can be cleaned by soft cloth). Also, install new cartridge to identify if cartridge or printer problem.
