This is the only printer I've seen that can take a 8.5x4 business check without jamming. My customer did get the error after clearing a paper jam. I replaced the cartridges. Then said there is something wrong with the black ink. Cleaned the cartridge contacts on the head and it worked. Then stopped, same error. Also if anyone knows a printer that can take a 8.5x4 check without jamming, please contact me
