Unit Defective
2007-12-17I purchased this photo conductor unit due to printer quality issues which I attributed to a worn out photo conductor unit. The replacement unit did not resolve the issues. After multiple attempts to troubleshoot the issue with the printer, I decided to buy a new printer - the exact same model. When the new printer came, I installed this photo conductor unit instead of opening the new one that came with the printer since I had paid $125 for the replacement unit and had not even used it. Once installed in the new printer, I had the same issues. I replaced it with the unit that came with the new printer and the issues were immediately resolved. So this defective unit cost me $125 + $500 for a new printer .. quite an expensive defect.
