Hi, I am from Serbia Europe. I have old printers Novajet pro 60e, and Novajet 850. On first main board is dead and on second cartridge board iz dead too. In serbia there is there is no more parts for this printers. Is there any option on NJ850 to turn off set of cartridges, as it recognizes 4 and 4 is not, and does not allow printing. In options there is an option to choose which set of cartridges will print, but also it does not allow printing until it detects a second set of cartridges, and that is impossible because the board is dead. I would like to print only with 4 cartridges.
If You have some service manuals, codes for service mode.
Please help me.
