Testing Process

EP 4000 cartridges are tested using two methods to ensure maximum reliability. Preliminary testing with the LT-777 Universal Cartridge Analyzer verifies proper operation of the magnetic roller, OPC drum, cartridge charging system, wiper and recovery blades. Final testing is accomplished by visual inspection of the cartridge and of the printed pages produced from the finished cartridge. By testing the cartridge in the appropriate printer, proper operation is verified. Final test pages include grey scale and black level tests and character formation tests.

Each toner cartridge is packaged in either our OEM generic box, to satisfy the needs of our retail store clients, or our own Envirolaser packaging. Both types of packaging are 100% recyclable, being composed of corrugated paper and pressed paper molded materials. The anti-static, mylar film bag is the only component of our package which is not recyclable.

Open the clamshell cover of printer and remove spent toner cartridge. While holding replacement toner cartridge in a horizontal orientation, gently rock cartridge side to side and front to back to ensure proper toner distribution. Remove seal. Insert toner into proper location on printer. Close cover and print 5 to 10 pages to ensure proper cartridge operation.

Any defective cartridge is replaced at no additional charge, or a credit or refund is provided to the client. Additionally, if a defective cartridge is shown to have damaged the printer, the required repair or replacement of the printer will be at no additional charge.
