Midwest Laser, Inc. follows a specific check-list for our in-house testing, which includes:
Visual inspection of packaging and labeling: We look at package quality and accuracy of information as well as lot / barcode information.
Visual inspection of cartridge: We look for apparent leaks, blemishes, damages, etc.
Seal tape test: We make sure seal tapes are functioning properly and can be pulled with no problems.
Printer recognition test: Each cartridge is installed in a printer to make sure cartridge is recognized.
Print quality testing: We use a number of test patterns to inspect overall print quality, density, color, text, etc.
Testing process: We look for fusing issues, abnormal banding or streaks, backgrounding, ghosting, and other potential issues that could lead to defectives.
Full yield test: We will also run a full yield test on cartridges to ensure the cartridge can print up to the stated yields.
