I followed the instructions in the maintenance section, and found that, despite trying four different Black Cartridges, all of which, AFAIK, are OK and contain ink, the machine indicated a Black Cartridge problem. The odd thing is that no colour is printed, yet the black portion of a document I tried printed OK. Also some parts of a test document which starts with the Alphabet in various sizes of font, are missing altogether. The machine has run OK with serial (USB) connection ever since I bought it (second hand) some years ago, but I decided to change to Parallel connection to see if that would cure the problems. Now, although it powers up OK, and the cartridge carriage moves as it should when the cover is opened, it won't print at all - i.e. nothing happens, when I select print, although the printer is 'installed & ready for use' Maybe I'll have to replace the printer after all!
