Hi All, 

After taking a look at the Large Format Printer in the lab it will need at minimum a Maintenance Cartridge. It is highly unlikely that any other parts would be required as the print cartridge - if gunged up - can probably be cleaned and made to work and we have additional ink cartridges if any of the ink is unusable

let me know your thoughts but I believe there is a high likelihood that this would be the only required part
