The doctor blade must be positioned with great accuracy when remanufacturing color cartridges used in HP CP1515, CP1525, CP2025, Canon LBP-5050, LBP-7200c and related printers. Gapping tools are unreliable and inconsistent, which can lead to print defects. Static Control's Doctor Blade Shims for color cartridges are the new standard for accuracy. Doctor Blade Shims also are the most remanufacturing-friendly option because they are quick and easy to use.
