The doctor (metering) blade is critical for proper toner charging and the regulation of the amount of toner available on the magnetic developer roller (mag roller). Damage to the doctor blade coating or blade surfaces can be difficult to see. If the doctor blade is re-used print defects such as vertical streaking, toner starvation and tire tracking can result. For consistent, defect-free cartridge performance Static Control recommends replacing the doctor blade with each remanufacturing cycle.

Static Control’s replacement doctor blade for use in HP LaserJet 9000 cartridges delivers OEM-comparable print results, when used with Static Control’s replacement toners , drum and chips .
