Replace the rollers and pads.
The media edges are locked together. Flex the media stack before loading it into the device. Do not
fan the media.

The media is of poor quality. Check the media type and quality (see Media specifications

cartridge. If a shutter does not open, replace the print cartridge.
The registration assembly is defective. If the registration arm is dirty, clean it. If the arm is scarred or
